Turning Bacteria into Fuel: Cyanobacteria Designed for Solar-Powered Highly Efficient Production of Biofuels  

SciTech Connect

Broad Funding Opportunity Announcement Project: ASU is engineering a type of photosynthetic bacteria that efficiently produce fatty acidsa fuel precursor for biofuels. This type of bacteria, called Synechocystis, is already good at converting solar energy and carbon dioxide (CO2) into a type of fatty acid called lauric acid. ASU has modified the organism so it continuously converts sunlight and CO2 into fatty acidsoverriding its natural tendency to use solar energy solely for cell growth and maximizing the solar-to-fuel conversion process. ASUs approach is different because most biofuels research focuses on increasing cellular biomass and not on excreting fatty acids. The project has also identified a unique way to convert the harvested lauric acid into a fuel that can be easily blended with existing transportation fuels.

Turning Bacteria into Biofuel: Development of an Integrated Microbial Electrocatalytic (MEC) System for Liquid Biofuel Production from CO2  

Science Conference Proceedings (OSTI)

Electrofuels Project: LBNL is improving the natural ability of a common soil bacteria called Ralstonia eutropha to use hydrogen and carbon dioxide for biofuel production. First, LBNL is genetically modifying the bacteria to produce biofuel at higher concentrations. Then, LBNL is using renewable electricity obtained from solar, wind, or wave power to produce high amounts of hydrogen in the presence of the bacteriaincreasing the organisms access to its energy source and improving the efficiency of the biofuel-creation process. Finally, LBNL is tethering electrocatalysts to the bacterias surface which will further accelerate the rate at which the organism creates biofuel. LBNL is also developing a chemical method to transform the biofuel that the bacteria produce into ready-to-use jet fuel.

Basic Bacteria Basic Bacteria Name: Valerie Location: N/A Country: N/A Date: N/A Question: I'm doing a science project on bacteria. WHat I'm doing is washing forks with different dishwashing liquids, then wiping any remaining bacteria on to Agar petri dishes. Then incubating it and seeing which soap removed the most. My question is what kind of bacteria would be growing? and also do I just count the colonies to compare? and how long and at what temperature should I incubate this bacteria? Thank you very much for your time. I'll be looking forward to your response. Replies: The temperature is easy: 37 degrees C is optimal for many bacteria. The medium will determine which bacteria grow best. So if you don't see growth on one medium, but you see growth on another, it tells you that there is a difference in nutrients present in those media that is required for that bacteria. Look at your plates after 24 hr, then put them back in the incubator (keep them sterile) and look at them after 48 hrs--do you see the difference? any slow-growing bacteria visible or did the fast-growing take over the complete plate?

Replies: I hope I understand your question. The time it takes to get your food done is sufficient to kill all bacteria--but not the spores of certain bacteria--both by microwave cooking and in a conventional oven. The spores are not a problem when the food is consumed directly but can be a health hazard when food is bottled and stored.

Magnet Coil Shorted Turn Detector  

Science Conference Proceedings (OSTI)

The Magnet Coil Shorted Turn Detector has been developed to facilitate the location of shorted turns in magnet coils. Finding these shorted turns is necessary to determine failure modes that are a necessary step in developing future production techniques. Up to this point, coils with shorted turns had the insulation burned off without the fault having been located. This disassembly process destroyed any chance of being able to find the fault. In order to maintain a flux balance in a coupled system such as a magnet coil, the current in a shorted turn must be opposed to the incident current. If the direction of the current in each conductor can be measured relative to the incident current, then the exact location of the short can be determined. In this device, an AC voltage is applied to the magnet under test. A small hand held B-dot pickup coil monitors the magnetic field produced by current in the individual magnet conductors. The relative phase of this pickup coil voltage is compared to a reference signal derived from the input current to detect a current reversal as the B-dot pickup coil is swept over the conductors of the coil under test. This technique however, is limited to only those conductors that are accessible to the hand held probe.

Counting Bacteria  

NLE Websites -- All DOE Office Websites (Extended Search)

Counting Bacteria Counting Bacteria Name: Tammy Location: N/A Country: N/A Date: N/A Question: I am working with my daughter on her Science Fair Project. We are testing daily items that we come in contact with to see how many germs and bacteria it has. How can we differentiate between the types of bacteria? How can we decide which one has the most? We are using the growth medium Agar in petri dishes. Where can I find more scientific info as to why this happens so we can write up the project? Replies: These are complex questions. First, the agar medium is used as a solid phase so that one can see colonies formed. These are round mounds of growth because bacteria multiply in all directions, but they cannot normally move in or on a solid phase so they remain at the site of multiplication. Every bacterial cell can multiply into a colony. Thus, the number of colonies is a measure for the number of cells present, if you have taken quantitative samples. If you want to quantitate, you should try to standardize your samples (for example, use 1 ml liquid to wash surfaces, food particles, 1 ml of liquids, etc. and add of this one drop (with a micropipette would be more accurate) per agar plate and let the drop form a tear on the plate. The number of colonies that grow in this tear are a measure for the original number of bacteria present in the drop, because each colony is derived from a single bacterial cell.

Bacteria Odors Bacteria Odors Name: Jason Location: N/A Country: N/A Date: N/A Question: I am doing a science project on food decomposition. I would like to know why food -- especially meat--smells bad when it goes bad. Also Why does bread grow mold and why is it green and blue? Thank you. Replies: Jason, When food is being eaten by bacteria, they produce byproducts just like we do. The compounds they produce cause the smell of rotten meat. There is a reason we don't like that smell: it warns us that that food is probably unsafe to eat. So biology has built in a safety rule: you would not normally eat something that you don't like the smell of. The molds on bread are a special kind that like bread. Their spores are everywhere but only when we leave our bread long enough can they grow to sufficient numbers so that we can see them. Again, you can smell the bread is off, you can see it, and if you hadn't noticed you will taste it. However you should not eat bread with molds on: they produce toxic substances. I don't think there is a reason for them to be green and blue, at least I don't know it.

Martian bacteria? Martian bacteria? Name: clement Status: N/A Age: N/A Location: N/A Country: N/A Date: Around 1993 Question: Is it possible for there to be life of anaerobic bacteria in the ice caps of the planet Mars? Replies: As far as I know, there is no evidence against such life on Mars, so the short answer is: yes. Jade Sure -- except that it would be pretty limited in its lifestyle - - no cable TV for this bug. Because the temperatures on Mars can reach to below -100 C at the poles, life would be extremely difficult, and the lack of nutrients anywhere except from inorganic chemical constituents in the soil or in the ice around the bacterial colonies would keep the menu fairly short. Oh, and do not rule out aerobes -- Mars has an atmosphere, though admittedly not much of one, and there are such organisms as microaerophiles and also microorganisms known as facultative anaerobes, which can grow in the presence of oxygen but which do not need it to survive

Which of these are gram-positive and gram-negative, and where can these be found? Also, what problems can they cause? When we culture these bacteria, we used four methods: plates, broth, slants, and pour plates. The media was made of TSB, TSA, NAP, and NAD. What is significant about these culturing methods? Replies: I could give you the answer to that question but it is more informative, and fun, to find out yourself. Start with the NCBI library online (http://www.ncbi.nlm.nih.gov/) and do a query with the species name, and 'virulence' if you want to know what they're doing to us. Have a look at the taxonomy devision to see how they are related. To find out if they're gram-pos or neg you should do a gram stain if you can. Otherwise you'll find that information in any bacteriology determination guide. Your question about the media is not specific enough so I can't answer it.

Bacteria: Good or Bad?  

NLE Websites -- All DOE Office Websites (Extended Search)

Bacteria: Good or Bad? Bacteria: Good or Bad? Name: Talei Location: N/A Country: N/A Date: N/A Question: Is bacteria good for you? Replies: both good and bad. Without bacteria we would die, but some bacteria could easily kill us: it all depends which ones they are. The good ones, those we need to survive, are there to digest our food (in our intestines) and to live on our skin and in our mouth. By doing so they provide a protection against bad bacteria, that make you sick, and these are called 'pathogenic bacteria'. Those bugs take their chance if your immune system is weakened, or if they manage to get into your body in large amounts, by contaminated food for instance. Anyway, the simple question has a complicated answer. If you're interested, read more about bacteria, both good and bad, at www.bacteriamuseum.org

Ampicillin and Bacteria Ampicillin and Bacteria Name: sara Location: N/A Country: N/A Date: N/A Question: could you please explain fully how ampicillian destroys E.coli cells? Replies: Ampicillin is an antibiotic belonging to the group of beta-lactam antibiotics. These will kill Gram-negative bacteria to which E.coli and Salmonella belong. The antibiotic prevents the formation of peptidoglycan, an essential building block of the cell membrane. So the antibiotic prevents growth of cells. You can read more about antibiotics and how bacteria can become resistant against them at the Virtual Bacteria of Bacteria: http://www.bacteriamuseum.org Dr. Trudy wasenaar Unfortunately, I don't have my micro books with me, but I'll try. Bacteria have a unique compound in their cell walls called peptidoglycan. It is made of 2 types of sugar residues that are cross-linked (like a chain link fence) by tetrapeptides. Penicillin prevents the crosslinking of the sugars by breaking the tetrapeptides. These antibiotics are more effective against gram positive organisms (such as Staph.) than gram negative organisms (such as E coli) because gram pos. have more peptidoglycan in their cell walls. Some bacteria have adapted to this situation by having an enzyme called beta-lactamase that breaks the structure of the antibiotic open rendering it ineffective. I'm pretty sure ampicillin is a penicillin derivative and therefore has the same mode of action, but I would check to make sure if I were you.

I am wondering this because i have a science fair project and i am searching for a project dealing with bacteria. Replies: As far as I'm aware it is the heat that kill bacteria in a microwave, and they need quite some time to be dead. The spores that some kind of bacteria make to survive harsh conditions do not contain much water and they might survive microwaves. I'm not sure what bacteria do that can survive high dosis of radiation, like Deinococcus radiodurans. They can do this by a very efficient repair system for their DNA. My guess is that they would also be killed by the heat generated in a microwave but I haven't found any data on this.

NLE Websites -- All DOE Office Websites (Extended Search)

Anammox Bacteria? Anammox Bacteria? Micrograph courtesy Mike S. Jetten, Radboud Univ. The deep sediments and oxygen minimum zones of the world's oceans are assumed to be responsible for the majority of nitrogen loss on earth. The microbes responsible for the nitrogen loss were long unknown, but compelling evidence is now accumulating that marine anaerobic ammonium oxidizing (anammox) bacteria are responsible, making them very important players in the global nitrogen cycle. In marine ecosystems, the carbon and nitrogen cycles are closely connected. More knowledge of the regulation and mechanism of CO2 sequestration by anammox bacteria in the ocean will contribute to our understanding of the global biogeochemical cycles and their impact on climate change. Anammox bacteria are also able to synthesize the rocket fuel hydrazine from

Dish Bacteria Determination Dish Bacteria Determination Name: Ashlyn Status: student Grade: 6-8 Location: FL Country: USA Date: Summer 2011 Question: Is there a simple way to measure bacteria in cat's water dishes without doing something with Agar? To measure bacteria in a water bowl, do I need to use a microscope? I am thinking of using different materials (metal, plastic, and glass) to see which of those has the grows the most bacteria. Replies: Hello Ashlyn, That is a very good idea for a science project. Usually the best way to do a quantitative analysis of bacteria content is to take a measured amount of a liquid, plate it out on some type of agar and do a colony count. This will give a basic indication of bacterial load, but not differentiate the types of bacteria. The most common type of bacteria that causes a pink film to form on water bowls and showers, etc. is Serratia marcescens. It is a fairly harmless organism that reacts with standing water. It may only adhere to the walls of the container and not be 'free floating' in the water. A microscope would not likely help unless you were able to do special stains to help see the bacteria. You might also want to add stoneware or ceramic to your list. Just so you know stoneware or ceramic make the best containers for cats to drink out of. It keeps the water fresher: Maybe less bacteria? You might just have to rely on a visual inspection of the containers to see which has more pink per surface area.

Evaluation of machining dispersions for turning process  

E-Print Network (OSTI)

In this article we propose to extend the model of simulation of dispersions in turning based on the geometrical specifications. Our study is articulated around two trends of development: the first trend relates to the geometrical model. The geometrical model suggested must allow a follow-up of the geometry of the part during the simulation of machining. It is thus a question of carrying out a systematic treatment of the whole dimensioning and tolerancing process while being based on the principles of the \\DeltaL method. We also planned to integrate this type of specification in the model of simulation of machining suggested. It is more generally a question of extending the traditional model for better taking into account the multi axis specification of coaxiality and perpendicularity on the turned workpieces. The second trend of our study relates to the widening of the field of application of the model. We propose to extend the field of application of the model by taking into account the modifications of several parameters of the manufacturing process plans, likely to involve variations of dispersions.

Insulin and Bacteria Insulin and Bacteria Name: sid Location: N/A Country: N/A Date: N/A Question: Can you explain Insulin production in bacteria and its regulation by IPTG. Replies: Information on expression of eukaryotic genes in bacteria can be found in any molecular biology textbook. See for instance 'Recombinant DNA by Watson, Gilman, Witkowski and Zoller, 2nd Ed., chapter 23 where the cloning of insulin is described. The use of an IPTG inducable promoter (the promoter of LacZ is only active when the inductor IPTG is present) is also explained in text books, and even in catalogs of the companies selling the plasmids that are used for such experiments. With a bit of reading you'll become an expert! Dr. Wassenaar I'm not sure what IPTG is. But are you referring to recombinant DNA technology? First a human gene for insulin was isolated and cut out of the human chromosome with restriction enzymes. These are enzymes that cut DNA at very specific spots in the DNA. They are like DNA scissors. Then a small piece of DNA called a plasmid is isolated from a bacteria. The same restriction enzyme is used to cut the plasmid. The insulin gene from the human is inserted into the bacterial DNA and they are sealed together with an enzyme called ligase. The plasmid is reinserted into the bacteria and the bacteria will treat the human insulin gene as its own. When it comes time to make protein it will make the insulin as well. Bacteria reproduce very rapidly and are easily maintained. We can get vats of human insulin by this method.

Here's my problem, I cannot find what kind of bacteria (mainly) flourishes in the axilla (armpit) region. I have been on many different search engines- medical pages- and microbiology pages, and unfortuantely cannot come up with any answers. My school's science fair is March 3rd- so I am in desperate need of an answer!!! I need to be able to order the type of bacteria soon. Thank you. Replies: Try Staphylococcus epidermidis-it is a common organism that grows on the skin. It is not pathogenic (disease-causing) and can be used by students. You could try culturing your own armpit-use a sterile q-tip. Spread the q-tip on the agar plate and then take some of your antiperspirant or deodorant and make a dot in the middle of the plate. Incubate the plate and see if the bacteria are repelled or are resistant. I would measure the size of the zone so you can compare each type of deodorant, etc. You could also check if different people's bacteria are more or less resistant, ie if the same deodorant works for everyone. Each person's bacterial population are a little different. This would require volunteers who would be willing to stick a q-tip in their armpit! If you decide to do this, I would sample the armpit when it is moist, before a shower (dry, clean skin won't have as much bacteria). Good luck.

Lactose intolerant bacteria Lactose intolerant bacteria Name: Carolyn McPherson Age: N/A Location: N/A Country: N/A Date: N/A Question: A student scientist is looking for a method to induce lactose intolerance in E. coli bacteria. Is there a suggestion for a method? Thanks Replies: The prevailing wisdom among geneticists is that we cannot really "induce" lactose intolerance so much a we can "select" or "screen" for mutant bacteria that have become lactose intolerant. The idea is that mutations in particular genes do not occur as a response to some evolutionary or selective pressure; rather, mutations just happen randomly, and those that confer a growth advantage (in a particular situation) will help the bacterium grow faster than its siblings. In a previous session, I suggested one way to identify those bacteria; to induce mutations, any of several mutation-causing agents might be tried, including chemicals and UV light. In fact, one worthwhile experiment might be to see how various exposure to UV light might yield increasing numbers of lactose-intolerant mutants. For more details or discussion, you might write me directly (S. Triezenberg).

Fungus or bacteria?

Fungus or bacteria? Fungus or bacteria? Name: Gordon T Davis Location: N/A Country: N/A Date: N/A Question: My biology class is growing bacteria cultures taken from different areas on the school campus. How can we accurately classify bacteria from fungus in the petri dish? Replies: How advanced is your class? In general, fungi look like they are made of tiny threads, or they appear to have tiny dots on top of the colony. But this isn't fool-proof. There are lots of books out with good pictures of various bacteria and fungi; you need to be careful, though, since you could end up growing some things that you'd rather not have everyone exposed to - be sure to sterilize the culture dishes with bleach or in a pressure cooker (depending on the type of plate you are using!) before throwing them away. Also be sure that everyone uses sterile techniques, washes their hands thoroughly, doesn't get too close to the dishes with their faces, etc.

Testing for Bacteria Testing for Bacteria Name: Danielle Location: N/A Country: N/A Date: N/A Question: I have to do a science fair project. What I need to compare the relative bacterial levels in milk samples with different expiration dates. What can I use to test the bacteria? Please help! Replies: You want to see if there are bacteria present in milk of different expiration dates, and if so, what they do to the milk. So buy milk of different dates. You could test what effect storage temperature has on bacterial growth in milk. Use those different milk samples in their original package (don't open it!) and keep them at 37 degrees C, at room temperature, and in the fridge (measure how cold that is) for say 48 hrs.Then open the bottle or pack and see what happened to the milk. Do you see differences? Can you explain them? If you open the milk before the experiment you may get bacteria into the milk that otherwise would not have been there. The experiment with the closed bottles will tell you what is better, storage of milk at room temperature, warm, or cold.

purple sulfur bacteria? purple sulfur bacteria? The process by which plants and some bacteria can convert light energy to sugar, or photosynthesis, is crucial to global food webs, and complicated. Very little is known about the photosynthetic bacteria in the purple sulfur bacteria group, which may represent one of the most primitive photosynthetic organisms and are capable of carbon fixation and sequestration in both light and dark conditions with the help of sulfur compounds. Purple sulfur bacteria are autotrophic and can synthesize organic compounds from inorganic sources. Researchers hope to learn more by sequencing nine type strains of purple sulfur bacteria that are found in freshwater, brackish and marine systems. The information would lead to a better understanding of the process of photosynthesis as well as the global

Bacteria eats radioactive waste

Bacteria eats radioactive waste Bacteria eats radioactive waste Name: deenaharper Status: N/A Age: N/A Location: N/A Country: N/A Date: Around 1993 Question: In my studies, I have found that everything in this world is balanced. When something dies it is converted into life. Is there anything out there that could convert radioactive material into a harmless substance? Some sort of bacteria that consumes radiation? Replies: The reason why radiation is so harmful is that is produces free radicals in living tissue, that is, it de-stabilizes molecules by tearing off electrons due to intense energies. These free radicals start a chain reaction of destruction, de-stabilizing neighboring molecules. If this continues unchecked, cells die, genetic material are mutated, and tissue aging accelerates. It is somewhat like being burned. Fire oxidizes by a similar free radical reaction. (Hence the term "sun burn.") The natural defenses against free radical reactions in biological systems are antioxidants, which are enzymes, nutrients, and other chemicals, which quench free radical reactions. Without them, life would very quickly cease. To my knowledge, no microorganism has an antioxidant capacity great enough to withstand even minimal exposure to any type of radiation. Microorganisms are actually very susceptible to radiation, which is why heat and gamma irradiation are used to sterilize food, instruments, etc. However, you raise an interesting possibility in that perhaps one can be genetically engineered to have super- antioxidant capacity, but that may be beyond current technology. Plus, if any got loose, given the exponential rate of reproduction, they may become an uncontrollable health hazard, as it would be very difficult to destroy them!

An application for tunes and coupling evaluation from turn-by-turn data at the Fermilab Booster  

Science Conference Proceedings (OSTI)

A console application using the phasing of Turn-by-Turn signals from the different BPMs has been tested at the Fermilab Booster. This technique allows the on-line detection of the beam tunes during the fast Booster ramp in conditions where other algorithms were unsuccessful. The application has been recently expanded to include the computation of the linear coupling coefficients. Algorithm and measurement results are presented. Although improved by the phased sum technique the automatic identification of the tunes is not always successful. This makes the use of the on-line application difficult. Ideas for further improvements are under investigation. Measurements have indicated that the effect of the skew quadrupoles is by a factor 3 weaker than expected from the nominal optics. A calibration of the skew quadrupole circuits using the TBT data is planned.

Cellulose Degrading Bacteria? Cellulose Degrading Bacteria? One of the major DOE missions is the production of renewable fuels to reduce our dependence on foreign oil, and also to take the place of petroleum-based fuels as these resources dwindle. Biologically produced ethanol is one possible replacement for fossil fuels. Currently, ethanol is produced from corn starch, but there is much research into using lignocellulosic materials (those containing cellulose, hemicellulose, and lignin) as the raw material for ethanol production. Ethanol production from cellulose requires several steps: pretreatment with steam, acid, or ammonia; digestion of cellulose to sugars; and fermentation of sugars to ethanol. The slowest and most expensive step is the breakdown of cellulose, chemically accomplished by cellulases. The second and third

Why Sequence Bacteria from Stromatolites?  

NLE Websites -- All DOE Office Websites (Extended Search)

Bacteria from Stromatolites? Bacteria from Stromatolites? Marine stromatolites are formed by the interactions of several key bacterial groups, which precipitate repeating layers (laminae) of calcium carbonate (CaCO3). During 70% of the time life has occupied earth, stromatolites were a dominant biological community. Their associated microbial communities have played a significant role in carbon sequestration, preservation, and cycling during the evolution of life. Present-day marine stromatolite communities consist of cyanobacteria (both free-living filamentous cyanobacteria and coccoid endoliths), sulfate reducers (SRB), sulfur-oxidizers (SOB), and aerobic heterotrophs (including fermenters). The interactions of these key groups drive the organized precipitation of CaCO3. The marine stromatolite system, therefore, provides

Electrofuels Project: MIT is using solar-derived hydrogen and common soil bacteria called Ralstonia eutropha to turn carbon dioxide (CO2) directly into biofuel. This bacteria already has the natural ability to use hydrogen and CO2 for growth. MIT is engineering the bacteria to use hydrogen to convert CO2 directly into liquid transportation fuels. Hydrogen is a flammable gas, so the MIT team is building an innovative reactor system that will safely house the bacteria and gas mixture during the fuel-creation process. The system will pump in precise mixtures of hydrogen, oxygen, and CO2, and the online fuel-recovery system will continuously capture and remove the biofuel product.

Pylorii the only bacteria able to survive the acidic condition of the stomach, or are there others? Replies: Hi Lianne, Thanks for the question. Yes, other bacteria are able to survive the acidic conditions in the stomach. For instance, the bacteria that are present in acidopholus yougurt (and milk) are able to survive the stomach's acid and to repopulate the large intestine. These acidopholus bacteria are "good" bacteria and are useful in restoring bacterial colonies in the large intestine after a treatment of antibiotics. I hope this helps. Please let me know if you have more questions. Thanks Jeff I don't know, but I would be very surprised given the number of bacterial species, that H. Pylori is uniquely adapted to low pH environments.

Spectroscopic diagnostics for bacteria in biologic sample  

DOE Patents (OSTI)

A method to analyze and diagnose specific bacteria in a biologic sample using spectroscopy is disclosed. The method includes obtaining the spectra of a biologic sample of a non-infected patient for use as a reference, subtracting the reference from the spectra of an infected sample, and comparing the fingerprint regions of the resulting differential spectrum with reference spectra of bacteria in saline. Using this diagnostic technique, specific bacteria can be identified sooner and without culturing, bacteria-specific antibiotics can be prescribed sooner, resulting in decreased likelihood of antibiotic resistance and an overall reduction of medical costs.

Chemotactic selection of pollutant degrading soil bacteria  

DOE Patents (OSTI)

A method is described for identifying soil microbial strains which may be bacterial degraders of pollutants. This method includes: Placing a concentration of a pollutant in a substantially closed container; placing the container in a sample of soil for a period of time ranging from one minute to several hours; retrieving the container and collecting its contents; microscopically determining the identity of the bacteria present. Different concentrations of the pollutant can be used to determine which bacteria respond to each concentration. The method can be used for characterizing a polluted site or for looking for naturally occurring biological degraders of the pollutant. Then bacteria identified as degraders of the pollutant and as chemotactically attracted to the pollutant are used to innoculate contaminated soil. To enhance the effect of the bacteria on the pollutant, nutrients are cyclicly provided to the bacteria then withheld to alternately build up the size of the bacterial colony or community and then allow it to degrade the pollutant.

Biofuels from Solar Energy and Bacteria: Electrofuels Via Direct Electron Transfer from Electrodes to Microbes  

Science Conference Proceedings (OSTI)

Electrofuels Project: UMass is feeding renewable electricity to bacteria to provide the microorganisms with the energy they need to turn carbon dioxide (CO2) directly into liquid fuels. UMass energy-to-fuels conversion process is anticipated to be more efficient than current biofuels approaches in part because this process will leverage the high efficiency of photovoltaics to convert solar energy into electricity. UMass is using bacteria already known to produce biofuel from electric current and CO2 and working to increase the amount of electric current those microorganisms will accept and use for biofuels production. In collaboration with scientists at University of California, San Diego, the UMass team is also investigating the use of hydrogen sulfide as a source of energy to power biofuel production.

Previous collaborations between the University of Washington team and the DOE JGI involving both single genome and metagenomic sequencing have greatly enhanced the community's ability to explore the diversity of bacteria functionally active in metabolism of single carbon compounds, known as methylotrophs, isolated from Lake Washington (Seattle, Washington) sediment. Sequencing genomes of 50 methylotroph isolates from the Lake Washington will further enhance the methylotroph community knowledge database providing a much higher level of resolution of global (meta)transcriptomic and (meta)proteomic analyses, as well as species interaction studies, informing a better understanding of biogeochemical cycling of carbon and nitrogen.

Motility fractionation of bacteria by centrifugation  

E-Print Network (OSTI)

Centrifugation is a widespread laboratory technique used to separate mixtures into fractions characterized by a specific size, weight or density. We demonstrate that centrifugation can be also used to separate swimming cells having different motility. To do this we study self-propelled bacteria under the influence of an external centrifugal field. Using dynamic image correlation spectroscopy we measure the spatially resolved motility of bacteria after centrifugation. A significant gradient in swimming-speeds is observed for increasing centrifugal speeds. Our results can be reproduced by a model that treats bacteria as "hot" colloidal particles having a diffusion coefficient that depends on the swimming speed.

Why Sequence Sulfur-Oxidizing Bacteria?  

NLE Websites -- All DOE Office Websites (Extended Search)

Sulfur-Oxidizing Bacteria? Sulfur-Oxidizing Bacteria? Several environmental problems, such as acid rain, biocorrosion, etc., are caused by sulfur compounds, such as sulfur dioxide (SO2) and hydrogen sulfide (H2S). A sustainable process to remove these sulfur compounds is the production of elemental sulfur from H2S-containing gas streams by the use of sulfide-oxidizing bacteria. In this process, H2S is absorbed into the alkaline solution in the scrubber unit, followed by the biological oxidation of H2S to elemental sulfur and the recycling of water. With this two-step process, a variety of gas streams (i.e., natural gas, synthesis gas, biogas, and refinery gas) can be treated. For the treatment of sulfate-containing waste streams, an extra step has to be introduced: the transformation of sulfate into H2S by sulfate-reducing bacteria. In

Fuel from Bacteria: Bioconversion of Carbon Dioxide to Biofuels by Facultatively Autotrophic Hydrogen Bacteria  

Science Conference Proceedings (OSTI)

Electrofuels Project: Ohio State is genetically modifying bacteria to efficiently convert carbon dioxide directly into butanol, an alcohol that can be used directly as a fuel blend or converted to a hydrocarbon, which closely resembles a gasoline. Bacteria are typically capable of producing a certain amount of butanol before it becomes too toxic for the bacteria to survive. Ohio State is engineering a new strain of the bacteria that could produce up to 50% more butanol before it becomes too toxic for the bacteria to survive. Finding a way to produce more butanol more efficiently would significantly cut down on biofuel production costs and help make butanol cost competitive with gasoline. Ohio State is also engineering large tanks, or bioreactors, to grow the biofuel-producing bacteria in, and they are developing ways to efficiently recover biofuel from the tanks.

Method and apparatus for reducing sample dispersion in turns and junctions of microchannel systems  

DOE Patents (OSTI)

The performance of microchannel devices is improved by providing turns, wyes, tees, and other junctions that produce little dispersions of a sample as it traverses the turn or junction. The reduced dispersion results from contraction and expansion regions that reduce the cross-sectional area over some portion of the turn or junction. By carefully designing the geometries of these regions, sample dispersion in turns and junctions is reduced to levels comparable to the effects of ordinary diffusion. A numerical algorithm was employed to evolve low-dispersion geometries by computing the electric or pressure field within candidate configurations, sample transport through the turn or junction, and the overall effective dispersion. These devices should greatly increase flexibility in the design of microchannel devices by permitting the use of turns and junctions that do not induce large sample dispersion. In particular, the ability to fold electrophoretic and electrochrornatographic separation columns will allow dramatic improvements in the miniaturization of these devices. The low-lispersion devices are particularly suited to electrochromatographic and electrophoretic separations, as well as pressure-driven chromatographic separation. They are further applicable to microfluidic systems employing either electroosrnotic or pressure-driven flows for sample transport, reaction, mixing, dilution or synthesis.

New method studies living bacteria cells New method studies living bacteria cells Researchers at the U.S. Department of Energy's Argonne National Laboratory have found a new way to study individual living bacteria cells and analyze their chemistry. In research published today in Science, the scientists used high-energy X-ray fluorescence measurements for mapping and chemical analyses of single free-floating, or planktonic, and surface-adhered, or biofilm, cells of Pseudomonas fluorescens. The results showed differences between the planktonic and adhered cells in morphology, elemental composition and sensitivity to hexavalent chromium, a heavy-metal contaminant and a known carcinogen. The biofilm cells were more tolerant of the contaminant, while it damaged or killed the planktonic cells. Experimental data from sector 1

Dynamics of stainless steel turning: Analysis by flicker-noise spectroscopy  

E-Print Network (OSTI)

We use flicker-noise spectroscopy (FNS), a phenomenological method for the analysis of time and spatial series operating on structure functions and power spectrum estimates, to identify and study harmful chatter vibrations in a regenerative turning process. The 3D cutting force components experimentally measured during stainless steel turning are analyzed, and the parameters of their stochastic dynamics are estimated. Our analysis shows that the system initially exhibiting regular vibrations associated with spindle rotation becomes unstable to high-frequency noisy oscillations (chatter) at larger cutting depths. We suggest that the chatter may be attributed to frictional stick-and-slip interactions between the contact surfaces of cutting tool and workpiece. We compare our findings with previously reported results obtained by statistical, recurrence, multifractal, and wavelet methods. We discuss the potential of FNS in monitoring the turning process in manufacturing practice.

Diamond-turning HP-21 beryllium to achieve an optical surface  

SciTech Connect

Investigation of diamond turning on beryllium was made in anticipation of obtaining an optical finish. Although results of past experiences were poor, it was decided to continue diamond turning on beryllium beyond initial failures. By changing speed and using coolant, partial success was achieved. Tool wear was the major problem. Tests were made to establish and plot wear as a function of cutting speed and time. Slower speeds did cause lower wear rates, but at no time did wear reach an acceptable level. The machine, tools, and procedure used were chosen based on the results of preliminary attempts and on previous experience. It was unnecessary to use an air-bearing spindle because tool failure governed the best finish that could be expected. All tools of diamond composition, whether single crystal or polycrystalline, wore at unacceptable rates. Based on present technology, it must be concluded that beryllium cannot be feasibly diamond turned to achieve an optical finish. (22 fig.) (auth)

PROTON RADIOGRAPHY EXAMINATION OF UNBURNED REGIONS IN PBX 9502 CORNER TURNING EXPERIMENTS  

SciTech Connect

PBX 9502 Corner Turning Experiments have been used with various diagnostics techniques to study detonation wave propagation and the boosting of the insensitive explosive. In this work, the uninitiated region of the corner turning experiment is examined using Proton Radiography. Seven transmission radiographs obtained on the same experiment are used to map out the undetonated regions on each of three different experiments. The results show regions of high-density material, a few percent larger than initial explosive density. These regions persist at nearly this density while surrounding material, which has reacted, is released as expected. Calculations using Detonation Shock Dynamics are used to examine the situations that lead to the undetonated regions.

Study on the relationship between left-turn traffic operations and safety at signalized intersections  

E-Print Network (OSTI)

Intersections are the most complex locations in a traffic system and are likely to have a higher crash count than any other location in the system. Intersection safety is related to traffic operations, such as traffic signal and approaching volume. The objective of this study is to determine the contributing factor for left-turn crashes at signalized intersections by a statistical modeling process and to develop crash prediction models. Potential contributing factors representing the characteristic of a left-turn operation were identified and considered for inclusion in crash prediction models. HCS (Highway Capacity Software) 2000 was utilized for computing some traffic indicators such as volume to capacity ratio for potential inclusion in the models. Three years of crash data were collected in the College Station area. The Signal timing and Volume data were obtained from public works in College Station. The volume data was sorted into three time periods and signal timing data were obtained for three different time periods: AM, noon, and PM. The division of time periods results from timing plans being changed for different periods. Relationship between crash count and each factor was explored to identify whether the factor has the potential to influence the crash count. Afterwards, the prediction models were developed using the negative binomial structure because of many zero samples. Akaike Information Criteria was used for selecting the model having the best fit. Wald tables provided that variables have significance in affecting the left-turn crash count. Left-turn type, sequence, volume, control delay, and post speed limit were identified as significant factors impacting left-turn crash count at a signalized intersection.

An interim report on the materials and selection criteria analysis for the Compact Ignition Tokamak Toroidal Field Coil Turn-to-Turn Insulation System  

Science Conference Proceedings (OSTI)

Design criteria for the Compact Ignition Tokamak, Toroidal-Field (TF) Coil, Turn-to-Turn Insulation System require an insulation sheet and bonding system that will survive cryogenic cycling in a radiation environment and maintain structural integrity during exposure to the significant compressive and shear loads associated with each operating cycle. For thermosetting resin systems, a complex interactive dependency exists between optimum peak value, in-service property performance capabilities of candidate generic materials; key handling and processing parameters required to achieve their optimum in-service property performance as an insulation system; and suitability of their handling and processing parameters as a function of design configuration and assembly methodology. This dependency is assessed in a weighted study matrix in which two principal programmatic approaches for the development of the TF Coil Subassembly Insulation System have been identified. From this matrix study, two viable approaches to the fabrication of the insulation sheet were identified: use of a press-formed sheet bonded in place with epoxy for mechanical bonding and tolerance take-up and formation of the insulation sheet by placement of dry cloth and subsequent vacuum pressure impregnation. Laboratory testing was conducted to screen a number of combinations of resins and hardeners on a generic basis. These combinations were chosen for their performance in similar applications. Specimens were tested to screen viscosity, thermal-shock tolerance, and cryogenic tolerance. Cryogenic shock and cryogenic temperature proved to be extremely lethal to many combinations of resin, hardener, and cure. Two combinations survived: a heavily flexibilized bisphenol A resin with a flexibilized amine hardener and a bisphenol A resin with cycloaliphatic amine hardener. 7 refs., 12 figs., 6 tabs.

The structures, called amyloid fibrils, are also implicated in neurodegenerative conditions such as Alzheimer's and Parkinson's, and in prion diseases like Creutzfeldt-Jacob and mad cow disease. The results pinpoint a critical intermediate step in the chemical pathway that leads to amyloid fibril formation. With the new culprit in view, future work could target a possible treatment, such as designing an inhibitor to interfere with the harmful pathway. The results also helped

Theoretical tool movement required to diamond turn an off-axis paraboloid on axis  

SciTech Connect

High-quality, off-axis parabolic reflectors, required by the CTR and laser-fusion programs at Lawrence Livermore Laboratory (LLL) and other ERDA laboratories, are currently manufactured by hand. There are several drawbacks to this method, including lead times of up to a year, costs in excess of $75,000 for a small reflector, and unsatisfactory limits to the tolerances obtainable. This situation has led to a search for cheaper and more accurate methods of manufacturing off-axis paraboloids. An alternative method, turning the workpiece about its axis on a diamond-turning machine, is presented, and the equations describing the necessary tool movement are derived. A discussion of a particular case suggests that the proposed technique is feasible. (auth)

Flow and heat transfer due to a buoyant ceiling jet turning downward at a corner  

Science Conference Proceedings (OSTI)

An experimental investigation has been carried out on the flow and heat transfer characteristics of a horizontal buoyant ceiling jet that turns downward at a corner to yield a vertical negatively buoyant wall flow. In this study, a two-dimensional jet of heated air is discharged adjacent to the lower surface of an isothermal horizontal plate. An isothermal vertical plate is attached at the other end of the horizontal surface, making a right angle corner. The vertical penetration distance of the resulting downward flow is measured and is related to the inflow conditions, particularly to the temperature and velocity at the jet discharge. This penetration distance is found to increase as the distance between the discharge location and the corner is reduced and also as the relative buoyancy level in the inlet flow is decreased. Velocity and temperature measurements are also carried out over the flow region. These indicate that the ceiling flow separates from the horizontal surface just before reaching the corner and then reattaches itself to the vertical wall at a finite distance vertically below the corner. The local surface heat flux measurements show a minimum in the heat transfer rate before the turn, along with a recovery in the heat transfer rate after the turn and the existence of a small recirculation zone near the corner. The net entrainment into the flow and heat transfer rate to the solid boundaries are also measured and correlated with the jet discharge conditions. 22 refs., 12 figs., 1 tab.

Phylogenetic Distribution of Potential Cellulases in Bacteria  

E-Print Network (OSTI)

Project Goals: The main goal of this project is to connect diverse microbial groups with the extracellular enzyme systems that catalyze the decay of organic material. We will also determine whether different groups of microbes and their enzymes respond to environmental changes, and whether they can recover from such changes. Finally, we will develop mathematical models to predict the responses of microbial communities and their associated functions under new environmental conditions. In most terrestrial ecosystems, the depolymerization of plant cell wall is the rate limiting step in the turnover of organic material. The composition of plant detritus is known to depend mainly on enzymes produced by microorganisms. This raises the question: which phylogenetic lineages of microorganisms can degrade plant cell wall material, including cellulose? To address this question, we compared the distribution of Glycoside Hydrolases (GH) potentially related to the cellulose degradation among 3744 bacteria. Some phylogenetic groups are especially rich in GHs whereas some are very poor. For example, in bacteria from the Bacteroidetes phylum ~40 GHs (from the families 1,

Detection of phenols using engineered bacteria  

DOE Patents (OSTI)

Detection of phenols using engineered bacteria. A biosensor can be created by placing a reporter gene under control of an inducible promoter. The reporter gene produces a signal when a cognate transcriptional activator senses the inducing chemical. Creation of bacterial biosensors is currently restricted by limited knowledge of the genetic systems of bacteria that catabolize xenobiotics. By using mutagenic PCR to change the chemical specificity of the Pseudomonas species CF600 DmpR protein, the potential for engineering novel biosensors for detection of phenols has been demonstrated. DmpR, a well-characterized transcriptional activator of the P. CF600's dmp operon mediates growth on simple phenols. Transcription from Po, the promoter heading the dmp operon, is activated when the sensor domain of DmpR interacts with phenol and mono-substituted phenols. By altering the sensor domain of the DmpR, a group of DmpR derivatives that activate transcription of a Po-lacZ fusion in response to eight of the EPA's eleven priority pollutant phenols has been created. The assays and the sensor domain mutations that alter the chemical specificity of DmpR is described.

This project is concerned with the structure and function of the unique antenna system found in the green photosynthetic bacteria. The antenna system in these organisms is contained within a vesicle known as a chlorosome, which is attached to the cytoplasmic side of the cell membrane. Additional antenna pigments and reaction centers are contained in integral membrane proteins. Energy absorbed by the bacteriochlorophyll c (BChl c) pigments in the chlorosome is transferred via a baseplate'' array of BChl a antenna pigments into the membrane and to the reaction center. A schematic model of chlorosome structure is shown. This project is aimed at increasing our understanding of the organization of the pigments in the chlorosome and how the antenna system functions.

Discrete magic angle turning system, apparatus, and process for in situ magnetic resonance spectroscopy and imaging  

DOE Patents (OSTI)

Described are a "Discrete Magic Angle Turning" (DMAT) system, devices, and processes that combine advantages of both magic angle turning (MAT) and magic angle hopping (MAH) suitable, e.g., for in situ magnetic resonance spectroscopy and/or imaging. In an exemplary system, device, and process, samples are rotated in a clockwise direction followed by an anticlockwise direction of exactly the same amount. Rotation proceeds through an angle that is typically greater than about 240 degrees but less than or equal to about 360 degrees at constant speed for a time applicable to the evolution dimension. Back and forth rotation can be synchronized and repeated with a special radio frequency (RF) pulse sequence to produce an isotropic-anisotropic shift 2D correlation spectrum. The design permits tubes to be inserted into the sample container without introducing plumbing interferences, further allowing control over such conditions as temperature, pressure, flow conditions, and feed compositions, thus permitting true in-situ investigations to be carried out.

Treatment and Stabilization of Potentially Pyrophoric Radioactive Metal Chips and Turnings  

SciTech Connect

As part of the continuing mission to decontaminate, decommission, and restore environmental quality at multiple sites throughout the U.S. Department of Energy (US DOE) nuclear complex, approximately 2,000 containers of potentially pyrophoric radioactive metal chips and turnings, weighing over 192,000 kilograms have been identified. These wastes, mostly depleted uranium (DU) and thorium metals, must be treated to remove or immobilize a wide range of hazardous and toxic regulated waste constituents without igniting the radioactive metal. Also, the treated metal wastes must be placed in an inert condition to prevent any future pyrophoric problems during storage, transportation, and disposal. All secondary wastes resulting from treatment activities must have a pathway to final disposal or destruction, in accordance with all applicable US federal and state laws, and regulations. To further this mission and to begin reducing the pyrophoric radioactive metal inventories throughout the US DOE system, a contract was awarded to Perma-Fix Environmental Services, Inc. to develop appropriate treatment methods, prove those methods in a First Article Test (FAT), and treat US DOE's existing inventory of pyrophoric radioactive metal wastes. The FAT was performed successfully between October 2002 and December 2002 using four containers of waste from the Rocky Flats Environmental Technology Site. The treated chips and turnings from this FAT were shipped for disposal at a private land disposal facility in the State of Utah. Since the FAT, two full-scale treatment projects have been performed under the contract. Between November 6, 2003 and March 4, 2004, 478 containers of Hanford DU chip wastes in mineral oil and soil matrices were treated. The treated chip waste was returned for disposal at the permitted mixed waste landfill at the Hanford Site. Between February 5, 2004, and February 25, 2005, another 222 containers of Rocky Flats DU chip waste, comprised of three distinct physical waste forms, were treated and disposed at the same land disposal facility in Utah. Complicating this task was the wide variety of hazardous and toxic contaminants, and great variability in the physical waste form. The chemical contaminants included mineral oil, polychlorinated biphenyls (PCBs), numerous volatile and semi-volatile organic contaminants, and toxic metals. Three main physical waste forms were included in the US DOE pyrophoric radioactive metal waste inventory: (1) chips and turnings in oil, (2) chips and turnings in soil, and (3) chips and turnings in sludge. The successful treatment method had to be capable of removing oil, PCBs, and volatile organics without resulting in ignition of the pyrophoric metals. After successful removal of hazardous and toxic organic contaminants, the toxic metals remaining in the waste required further stabilization to limit their potential for long-term leaching in land disposal facilities. The final waste form and its packaging also had to comply with the waste acceptance criteria of the land disposal facilities at the US DOE Hanford Site, in Richland, Washington, and the private disposal facility in Utah. This paper will describe the treatment process, the challenges encountered and overcome, the lessons learned, and final quality of the treated chip waste. Disposal and/or destruction of secondary wastes from the treatment process will also be discussed. (authors)

Large scale dynamics of the Persistent Turning Walker model of fish behavior  

E-Print Network (OSTI)

This paper considers a new model of individual displacement, based on fish motion, the so-called Persistent Turning Walker (PTW) model, which involves an Ornstein-Uhlenbeck process on the curvature of the particle trajectory. The goal is to show that its large time and space scale dynamics is of diffusive type, and to provide an analytic expression of the diffusion coefficient. Two methods are investigated. In the first one, we compute the large time asymptotics of the variance of the individual stochastic trajectories. The second method is based on a diffusion approximation of the kinetic formulation of these stochastic trajectories. The kinetic model is a Fokker-Planck type equation posed in an extended phase-space involving the curvature among the kinetic variables. We show that both methods lead to the same value of the diffusion constant. We present some numerical simulations to illustrate the theoretical results.

PC and monitor night status: Power management enabling and manual turn-off  

SciTech Connect

While office equipment accounts for about 7 percent of commercial building energy use, this reflects considerable energy savings from the use of automatic power management. Most of these savings were gained through the use of low-power modes that meet the criteria of the U.S. EPA's Energy Star program. Despite this success, there are large amounts of additional savings that could be gained if all equipment capable of power management use were enabled and functioning. A considerable portion of equipment is not enabled for power management at all, enabled only partially, or is enabled but prevented from functioning. Additional savings could be gained if more equipment were turned off at night manually. We compiled results from 17 studies from the office equipment literature addressing PCs and monitors. Some factors important for annual energy use, such as power levels, have been documented elsewhere and are not covered. We review methods for estimating office equipment use patterns and energy use, and present findings on night status--power management and manual turn-off rates. In early studies, PC power management was often found to function in 25 percent or less of the Energy Star compliant units (10 percent of all PCs). However, recent assessments have found higher rates, and we estimate that for Energy Star models, 35 percent of PC CPUs and 65 percent of PC monitors are enabled for power management. While the data lack statistical rigor, they can be used to estimate the magnitude of current and potential power management savings, which we did for major types of office equipment. The data also make clear that the topic of enabling rates, and the factors which influence them, deserve greater scrutiny.

REDUCTIONS WITHOUT REGRET: AVOIDING WRONG TURNS, ROACH MOTELS, AND BOX CANYONS  

SciTech Connect

This is the third of three papers (in addition to an introductory summary) aimed at providing a framework for evaluating future reductions or modifications of the U.S. nuclear force, first by considering previous instances in which nuclear-force capabilities were eliminated; second by looking forward into at least the foreseeable future at the features of global and regional deterrence (recognizing that new weapon systems currently projected will have expected lifetimes stretching beyond our ability to predict the future); and third by providing examples of past or possible undesirable outcomes in the shaping of the future nuclear force, as well as some closing thoughts for the future. In this paper, we provide one example each of our judgments on what constitutes a box canyon, a roach motel, and a wrong turn: ? Wrong Turn: The Reliable Replacement Warhead ? Roach Motel: SRAM T vs the B61 ? A Possible Box Canyon: A Low-Yield Version of the W76 SLBM Warhead Recognizing that new nuclear missions or weapons are not demanded by current circumstances ? a development path that yields future capabilities similar to those of today, which are adequate if not always ideal, and a broader national-security strategy that supports nonproliferation and arms control by reducing the role for, and numbers, of nuclear weapons ? we briefly consider alternate, less desirable futures, and their possible effect on the complex problem of regional deterrence. In this regard, we discuss the issues posed by, and possible responses to, three example regional deterrence challenges: in-country defensive use of nuclear weapons by an adversary; reassurance of U.S. allies with limited strategic depth threatened by an emergent nuclear power; and extraterritorial, non-strategic offensive use of nuclear weapons by an adversary in support of limited military objectives against a U.S. ally.

Solar powered automatic turn-on control (spa-toc) unit and method  

SciTech Connect

Orderly control of power applied by a photovoltaic solar panel d.c. source to a load is attained despite varying long and short term solar conditions by coupling power from the panel to an inverter in response to the panel voltage exceeding a predetermined level and preventing coupling of power from the panel to the inverter in response to the panel voltage being less than a predetermined level. The switching frequency of the inverter is controlled in response to the panel voltage so that approximately maximum power which the panel is capable of generating is supplied to the inverter for the incident solar energy on the panel at a given temperature. Power is supplied to the inverter by a series switch between the panel and inverter. The switch is activated into a conducting state in response to the panel voltage exceeding a predetermined value. The panel voltage controls the turn-on and turn-off levels of the series switch by a hysteresis effect, provided by connecting a dummy power dissipating load in shunt with the panel while the series switch is cut off. The dummy load has a value causing the panel output voltage to be less than the voltage for maximum panel output power. A similar series switch and hysteresis control is provided for control circuitry for the inverter. The series switch for supplying power to the control circuitry can be activated in response to the same voltage which activates the series switch for the inverter, or in response to a different voltage level.

Expanding beta-turn analogs for mimicking protein-protein hot spots  

E-Print Network (OSTI)

Solid-phase syntheses of two 14-membered ring peptidomimetics were done to determine whether or not a beta-turn structure can facilitate macrocyclization. NMR methods, together with CD and QMD calculations, do not fully support this assumption. However, cyclizations of more ordered structures like those of compounds 2 were more efficient than those for highly strained ring systems like 1. A small library of 18-membered ring peptidomimetics that accommodate an extra amino acid residue was synthesized on resin. Their syntheses were not complicated by head-to-tail dimer impurity, unlike those for previously synthesized 14-membered systems. These larger macrocycles exhibit beta-turn structures as verified by NMR, CD and QMD techniques. Moreover, two compounds in this series (3a and 3g) were shown to have agonistic properties for TrkC in cell survival assays. Dimerization of monovalent mimics was achieved first by modifying the organic template so that monovalent mimics with requisite functional groups can be synthesized. Second, the monovalent units were dimerized using sequential nucleophilic substitutions on fluorescently labeled dichlorotriazine. Our rationale to make bivalent compounds out of monovalent ones was justified when compound 4 was shown to bind TrkA with a 20 nM affinity. Reactions of amino acids with NH4SCN under acylating conditions produced 2-thiohydantoins in which the nitrogen of the amino acid (N1) was acylated. This was proven by 2-D NMR which showed no cross-peak between the NH signal observed and the C?-H of the amino acid. When the compound was deacylated, a new NH signal appeared and the corresponding cross-peak with the C?-H was observed. Solution-phase syntheses of non-peptidic mimics were achieved by doing a double substitution on a dihalogenated nitrobenzene scaffold. Sonogashira and SNAr reactions were done to install the required side-chains to give the desired compounds. These non-peptidic compounds can be easily adapted to our DTAF-Inp dimerization protocol since the nitro groups can be easily reduced. Attempts to make a spirotetracyclic peptidomimetic with three side chain mimics were done by synthesizing the spirocyclic diketopiperazine precursor. The synthesis of the DKP was achieved by making the cyclic quaternary amino acid that was coupled to another amino acid via the HOAt-EDC method. This protocol gave dipeptides in high yields. These dipeptides were deprotected and cyclized to the DKP under mildly acidic conditions in toluene.

Why sequence Alkaliphilic sulfur oxidizing bacteria for sulfur pollution

Alkaliphilic sulfur oxidizing Alkaliphilic sulfur oxidizing bacteria for sulfur pollution remediation? Burning sulfur-containing fuels, such as coal, oil, and natural gas, contributes significantly to global environmental problems, such as air pollution and acid rain, besides contributing to the loss of the ozone layer. One method of managing sulfur compounds released as byproducts from industrial processes is to scrub them out using chemical treatments and activated charcoal beds. A lower-cost solution relies on incorporating alkaliphic sulfur-oxidizing bacteria into biofilters to convert the volatile and toxic compounds into insoluble sulfur for easier removal. Discovered in the last decade, these bacteria have been found to thrive in habitats that span the full pH range. The bacteria could have applications

Gate-turn-off thyristors provide new level of power-flow control  

SciTech Connect

The availability of high-power, gate-turn-off (GTO) thyristors has made possible the development of a new class of solid-state devices that promise an unprecedented degree of control over the flow of power in the nation`s network. The first of these, a static compensator known as Statcom, which offers dynamic control over the flow of VArs into, or out of, the network, was unveiled last month at the Tennessee Valley Authority`s (TVA) Sullivan substation in eastern Tennessee. The principal element of the Statcom is a voltage-sourced inverter that converts dc voltage at its input terminals into a 3-phase alternating output voltage. To eliminate the quasi square wave that a single inverter would generate - along with unacceptable harmonics - the Statcom uses many such inverters, appropriately phase-shifted, and combines their outputs through electromagnetic linkages to produce a nearly sinusoidal output waveform. By numerous voltage additions and subtractions, eight inverters used in the Statcom generate a 48-pulse, nearly sinusoidal output waveform. The GTO-based inverters and electronic feedback control give the Statcom a dynamic performance far exceeding that of other reactive power compensators. In fact, the device can transition from full rated capacitive to full-rated VArs in approximately one-quarter cycle. Nominal rating of each inverter is 12.5 MVA. 12 figs.

The Turning Point: Perceptions and Policies Concerning Communist China during the Kennedy Years  

E-Print Network (OSTI)

When analyzing the policies of the John F. Kennedy administration towards the Peoples Republic of China, previous historians have focused on the lack of substantive change, emphasizing the continuity of action with the prior polices of the Dwight D. Eisenhower administration. At the same time, a number of historians have noted that it was during the years Kennedy was in office that a majority of the American people began viewing communist China as a greater threat to world peace than the Soviet Union. However, none have sought to explain this sizeable shift in public opinion, or analyze its potential impact on policy. This thesis incorporates archival materials with contemporary print and visual media to make a connection between the sources of public opinion shifts and a change in the assumptions upon which U.S. China policy was based. Almost from the moment the new president assumed office, Robert Komer at the National Security Council and Chester Bowles at the State Department began pushing for changes in China policy based on the assumptions that the communist regime was not a passing phase, would only become more powerful and over time constitute an inexorable greater threat to U.S. interests in Asia, and that rapprochement, rather than isolation, was the best means of ameliorating this threat. Together with James Thomson, Roger Hilsman, and eventually Walt Rostow, they pushed for the adoption of what A. Doak Barnett would later term Containment Without Isolation. While the Sino-Soviet split accentuated charges of Chinese anti-white racism and the Great Leap Forward reinforced the sense of Maos irrationality, the Sino-Indian War confirmed both rising Chinese power and their leaderships capacity for rational calculation. Meanwhile, in the popular culture, particularly motion pictures, the Yellow Peril enjoyed a revival as Chinese villains stepped to the fore, beginning to free themselves of their Soviet masters. However, while foreign Chinese were feared as never before, Chinese in America gained new acceptance. Laying the groundwork for the next five decades of China policy and enemy images, Kennedys Thousand Days constituted a turning point.

The catabolism of phenanthrene and naphthalene by bacteria  

E-Print Network (OSTI)

Thirteen strains of bacteria able to grow on phenanthrene were isolated from soil; they included fluorescent and non-fluorescent pseudomonads, vibrios and unidentified bacteria. Two of the pseudomonads, like Aeromonas sp. ~45~1, also grew on naphthalene. In all strains, growth on phenanthrene induced the enzyme responsible for the conversion of 1-hydroxy-2-naphthoate to 2-carboxybenzaldehyde, NAD-dependent 2-carboxybenzaldehyde dehydrogenase and protocatechuate oxygenase, but not salicylate hydroxylase, catechol oxygenase or NAD(P)H-dependent 1-hydroxy-2-naphthoate hydroxylase. Growth on naphthalene induced salicylate hydroxylase and catechol oxygenase. It is suggested that the catabolism of phenanthrene occurs via protocatechuate in all these bacteria, and that the pathways for degradation of phenanthrene and naphthalene are separate.

Unexpected photoreactivation of Vibrio harveyi bacteria living in ionization environment  

SciTech Connect

Bacteria undergoing environmental effects is extremely interesting for structural, mechanistic, and evolutionary implications. Luminescent bacteria that have evolved in a specific ambient have developed particular responses and their behavior can give us new suggestions on the task and production of luciferina proteins. To analyze the UV interaction under controlled laboratory conditions, we used photoluminescent bacterial strains belonging to a new species evolutionarily close to Vibrio harveyi sampled from a coastal cave with a high radon content that generates ionizing radiation. The survival of the bacterial strains was analyzed, in the light and in the dark, following a variety of genotoxic treatments including UV radiation exposure. The strains were irradiated by a germicide lamp. The results demonstrated that most of the strains exhibited a low rate of survival after the UV exposure. After irradiation by visible light following the UV exposure, all strains showed a high capability of photoreactivation when grown. This capability was quite unexpected because these bacteria were sampled from a dark ambient without UV radiation. This leads us to hypothesize that the photoreactivation in these bacteria might have been evolved to repair DNA lesions also induced by different radiation sources other than UV (e.g., x-ray) and that the luminescent bacteria might use their own light emission to carry out the photoreactivation. The high capability of photoreactivation of these bacteria was also justified by the results of deconvolution. The deconvolution was applied to the emission spectra and it was able to show evidence of different light peaks. The presence of the visible peak could control the photolysis enzyme.

Methods for Engineering Sulfate Reducing Bacteria of the Genus Desulfovibrio  

SciTech Connect

Sulfate reducing bacteria are physiologically important given their nearly ubiquitous presence and have important applications in the areas of bioremediation and bioenergy. This chapter provides details on the steps used for homologous-recombination mediated chromosomal manipulation of Desulfovibrio vulgaris Hildenborough, a well-studied sulfate reducer. More specifically, we focus on the implementation of a 'parts' based approach for suicide vector assembly, important aspects of anaerobic culturing, choices for antibiotic selection, electroporation-based DNA transformation, as well as tools for screening and verifying genetically modified constructs. These methods, which in principle may be extended to other sulfate-reducing bacteria, are applicable for functional genomics investigations, as well as metabolic engineering manipulations.

Engineering aspects of hydrogen production from photosynthetic bacteria  

DOE Green Energy (OSTI)

Certain photosynthetic bacteria (PSB), for example, Rhodopseudomonas capsulata, evolve hydrogen when placed in an anaerobic environment with light and a suitable organic substrate. An engineering effort to use such bacteria for large-scale hydrogen production from sunlight is described. A system to produce 28,000 m/sup 3//day (1 x 10/sup 6/ ft/sup 3//day) of hydrogen has been designed on a conceptual level and includes hydrogen cleanup, substrate storage, and waste disposal. The most critical component in the design is the solar bacterial reactor. Several designs were developed and analyzed. A large covered pond concept appears most attractive. Cost estimates for the designs show favorable economics.

Oxidation and methylation of dissolved elemental mercury by anaerobic bacteria  

Science Conference Proceedings (OSTI)

Methylmercury is a neurotoxin that poses significant health risks to humans. Some anaerobic sulphate- and iron-reducing bacteria can methylate oxidized forms of mercury, generating methylmercury1-4. One strain of sulphate-reducing bacteria (Desulfovibrio desulfuricans ND132) can also methylate elemental mercury5. The prevalence of this trait among different bacterial strains and species remains unclear, however. Here, we compare the ability of two strains of the sulphate-reducing bacterium Desulfovibrio and one strain of the iron-reducing bacterium Geobacter to oxidise and methylate elemental mercury in a series of laboratory incubations. Experiments were carried out under dark, anaerobic conditions, in the presence of environmentally-relevant concentrations of elemental mercury. We report differences in the ability of these organisms to oxidise and methylate elemental mercury. In line with recent findings5, we show that Desulfovibrio desulfuricans ND132 can both oxidise and methylate elemental mercury. However, the rate of methylation of elemental mercury is only about one third the rate of methylation of oxidized mercury. We also show that Desulfovibrio alaskensis G20 can oxidise, but not methylate, elemental mercury. Geobacter sulfurreducens PCA is able to oxidise and methylate elemental mercury in the presence of cysteine. We suggest that the activity of methylating and non-methylating bacteria may together enhance the formation of methylmercury in anaerobic environments.

Apparatus and method for the desulfurization of petroleum by bacteria  

SciTech Connect

A method for treating petroleum with anaerobic microorganisms acting as biocatalysts that can remove sulfur atoms from hydrocarbon molecules, under anaerobic conditions, and then convert the sulfur atoms to hydrogen sulfide. The microorganisms utilized are from the family known as the "Sulfate Reducing Bacteria." These bacteria generate metabolic energy from the oxidation of organic compounds, but use oxidized forms of sulfur as an electron acceptor. Because the biocatalyst is present in the form of bacteria in an aqueous suspension, whereas the reacting substrate consists of hydrocarbon molecules in an organic phase, the actual desulfurization reaction takes place at the aqueous-organic interphase. To ensure adequate interfacial contacting and mass transfer, a biphasic electrostatic bioreactor system is utilized. The bioreactor is utilized to disperse and recoalesce a biocatalyst contained in the aqueous liquid phase into the organic liquid phase containing the sulfur. High-intensity electrical fields rupture the aqueous drops into a plurality of microdroplets and induce continuous coalescence and redispersion as the microdroplets travel through the organic phase, thus increasing surface area. As the aqueous microdroplets progress through the organic phase, the biocatalyst then reacts with the sulfur to produce hydrogen sulfide which is then removed from the bioreactor. The organic liquid, now free of the sulfur, is ready for immediate use or further processing.

Expansion of the Genomic Encyclopedia of Bacteria and Archaea  

SciTech Connect

To date the vast majority of bacterial and archaeal genomes sequenced are of rather limited phylogenetic diversity as they were chosen based on their physiology and/ or medical importance. The Genomic Encyclopedia of Bacteria and Archaea (GEBA) project (Wu et al. 2009) is aimed at systematically filling the gaps of the tree of life with phylogenetically diverse reference genomes. However more than 99 percent of microorganisms elude current culturing attempts, severely limiting the ability to recover complete or even partial genomes of these largely mysterious species. These limitations gave rise to the GEBA uncultured project. Here we propose to use single cell genomics to massively expand the Genomic Encyclopedia of Bacteria and Archaea by targeting 80 single cell representatives of uncultured candidate phyla which have no or very few cultured representatives.

Apparatus and method for the desulfurization of petroleum by bacteria  

DOE Patents (OSTI)

A method is described for treating petroleum with anaerobic microorganisms acting as biocatalysts that can remove sulfur atoms from hydrocarbon molecules, under anaerobic conditions, and then convert the sulfur atoms to hydrogen sulfide. The microorganisms utilized are from the family known as the ``Sulfate Reducing Bacteria``. These bacteria generate metabolic energy from the oxidation of organic compounds, but use oxidized forms of sulfur as an electron acceptor. Because the biocatalyst is present in the form of bacteria in an aqueous suspension, whereas the reacting substrate consists of hydrocarbon molecules in an organic phase, the actual desulfurization reaction takes place at the aqueous-organic interphase. To ensure adequate interfacial contacting and mass transfer, a biphasic electrostatic bioreactor system is utilized. The bioreactor is utilized to disperse and recoalesce a biocatalyst contained in the aqueous liquid phase into the organic liquid phase containing the sulfur. High-intensity electrical fields rupture the aqueous drops into a plurality of microdroplets and induce continuous coalescence and redispersion as the microdroplets travel through the organic phase, thus increasing surface area. As the aqueous microdroplets progress through the organic phase, the biocatalyst then reacts with the sulfur to produce hydrogen sulfide which is then removed from the bioreactor. The organic liquid, now free of the sulfur, is ready for immediate use or further processing. 5 figs.

Expansion of the Genomic Encyclopedia of Bacteria and Archaea  

Science Conference Proceedings (OSTI)

To date the vast majority of bacterial and archaeal genomes sequenced are of rather limited phylogenetic diversity as they were chosen based on their physiology and/ or medical importance. The Genomic Encyclopedia of Bacteria and Archaea (GEBA) project (Wu et al. 2009) is aimed to systematically filling the gaps of the tree of life with phylogenetically diverse reference genomes. However more than 99percent of microorganisms elude current culturing attempts, severely limiting the ability to recover complete or even partial genomes of these largely mysterious species. These limitations gave rise to the GEBA uncultured project. Here we propose to use single cell genomics to massively expand the Genomic Encyclopedia of Bacteria and Archaea by targeting 80 single cell representatives of uncultured candidate phyla which have no or very few cultured representatives. Generating these reference genomes of uncultured microbes will dramatically increase the discovery rate of novel protein families and biological functions, shed light on the numerous underrepresented phyla that likely play important roles in the environment, and will assist in improving the reconstruction of the evolutionary history of Bacteria and Archaea. Moreover, these data will improve our ability to interpret metagenomics sequence data from diverse environments, which will be of tremendous value for microbial ecology and evolutionary studies to come.

Fuel from Bacteria, CO2, Water, and Solar Energy: Engineering a Bacterial Reverse Fuel Cell  

Science Conference Proceedings (OSTI)

Electrofuels Project: Harvard is engineering a self-contained, scalable Electrofuels production system that can directly generate liquid fuels from bacteria, carbon dioxide (CO2), water, and sunlight. Harvard is genetically engineering bacteria called Shewanella, so the bacteria can sit directly on electrical conductors and absorb electrical current. This current, which is powered by solar panels, gives the bacteria the energy they need to process CO2 into liquid fuels. The Harvard team pumps this CO2 into the system, in addition to water and other nutrients needed to grow the bacteria. Harvard is also engineering the bacteria to produce fuel molecules that have properties similar to gasoline or diesel fuelmaking them easier to incorporate into the existing fuel infrastructure. These molecules are designed to spontaneously separate from the water-based culture that the bacteria live in and to be used directly as fuel without further chemical processing once theyre pumped out of the tank.

The Columbia University team is feeding the ammonia and CO2 into an engineered tank where the bacteria live. The bacteria capture the energy from ammonia and then use that energy to convert CO2 into a liquid fuel. When the bacteria use up all the ammonia, renewable electricity can regenerate it and pump it back into the systemcreating a continuous fuel-creation cycle. In addition, Columbia University is also working with the bacteria A. ferrooxidans to capture and use energy from ferrous iron to produce liquid fuels from CO2.

Issues involved with non-characterized control of methanotrophic bacteria  

SciTech Connect

Methane-utilizing bacteria, methanotrophs, have application as biocatalysts in the commodity chemical production, waste treatment and environmental remediation industries. Methanotrophs have the ability to oxidize many chemical compounds into more desired products, such as the production of propylene oxide. Methanotrophs can also degrade toxic compounds such as trichloroethylene. However, there are many physical, chemical and biological problems associated with the continuous oxidation of chemicals. These include, low mass transfer of methane, oxygen and propylene; toxicity of substrates and degradation products, and competition between the growth substrate, i.e., methane and chemical feed stock, e.g., propylene for the biocatalyst. To supervise methanotrophic bioprocesses, an intelligent control system must accommodate any biological limitations, e.g., toxicity, and mitigate the impact of the physical and chemical limitations, e.g., mass transfer of methane and the solubility of propylene. The intelligent control system must have the capability to assess the current conditions and metabolic state of the bacteria; recognize and diagnose instrument faults; and select and maintain sets of parameters that will result in high production and growth.

Lubricating bacteria model for branching growth of bacterial colonies, Phys  

E-Print Network (OSTI)

Various bacterial strains (e.g. strains belonging to the genera Bacillus, Paenibacillus, Serratia and Salmonella) exhibit colonial branching patterns during growth on poor semi-solid substrates. These patterns reflect the bacterial cooperative self-organization. Central part of the cooperation is the collective formation of lubricant on top of the agar which enables the bacteria to swim. Hence it provides the colony means to advance towards the food. One method of modeling the colonial development is via coupled reaction-diffusion equations which describe the time evolution of the bacterial density and the concentrations of the relevant chemical fields. This idea has been pursued by a number of groups. Here we present an additional model which specifically includes an evolution equation for the lubricant excreted by the bacteria. We show that when the diffusion of the fluid is governed by nonlinear diffusion coefficient branching patterns evolves. We study the effect of the rates of emission and decomposition of the lubricant fluid on the observed patterns. The results are compared with experimental observations. We also include fields of chemotactic agents and food chemotaxis and conclude that these features are needed in order to explain the observations. 1 I.

Bioaugmentation with engineered endophytic bacteria improves contaminant fate in phytoremediation  

SciTech Connect

Phytoremediation of volatile organic contaminants often proves not ideal because plants and their rhizosphere microbes only partially degrade these compounds. Consequently, plants undergo evapotranspiration that contaminates the ambient air and, thus, undermines the merits of phytoremediation. Under laboratory conditions, endophytic bacteria equipped with the appropriate degradation pathways can improve in plant degradation of volatile organic contaminants. However, several obstacles must be overcome before engineered endophytes will be successful in field-scale phytoremediation projects. Here we report the first in situ inoculation of poplar trees, growing on a TCE-contaminated site, with the TCE-degrading strain Pseudomonas putida W619-TCE. In situ bioaugmentation with strain W619-TCE reduced TCE evapotranspiration by 90% under field conditions. This encouraging result was achieved after the establishment and enrichment of P. putida W619-TCE as a poplar root endophyte and by further horizontal gene transfer of TCE metabolic activity to members of the poplar's endogenous endophytic population. Since P. putida W619-TCE was engineered via horizontal gene transfer, its deliberate release is not restricted under European genetically modified organisms (GMO) regulations.

Improved hydrogen photoproduction from photosynthetic bacteria and green algae  

DOE Green Energy (OSTI)

Photosynthetic bacteria evolve hydrogen at much higher rates than do other classes of photosynthetic microorganisms. In addition, they tolerate harsh environments, grow rapidly, and utilize both visible and near infrared light in photosynthesis. They do not split water, but this does not necessarily eliminate their potential use in future applied systems. They are easily manipulated genetically, and thus might be modified to metabolize common biomass waste materials in place of expensive defined organic substrates. Furthermore, the potential for increasing hydrogen photoproduction via genetic techniques is promising. Strains that partially degrade cellulose, have high photoproduction rates, or contain very large amounts of the enzymes associated with hydrogen metabolism have been isolated. Green algae also produce hydrogen but are capable of using water as a substrate. For example, C. reinhardi can evolve hydrogen and oxygen at a molar ratio approaching 2:1. Based upon effect of dichlorophenyl dimethylurea (a specific inhibitor of photosystem II, PSII) on hydrogen photoproduction in the wild type strain and upon results obtained with PSII mutants, one can demonstrate that water is the major source of electrons for hydrogen production. The potential efficiency of in vivo coupling between hydrogenase and the photosynthetic electron transport system is high. Up to 76% of the reductants generated by the electron transport system can be channeled directly to the enzyme for in vivo hydrogen production. Rates exceeding 170 ..mu..moles of H/sub 2/ mg Chl/sup -1/ hr/sup -1/ have been observed.

Plant Growth-Promoting Bacteria for Phytostabilization of Mine Tailings  

Science Conference Proceedings (OSTI)

Eolian dispersion of mine tailings in arid and semiarid environments is an emerging global issue for which economical remediation alternatives are needed. Phytostabilization, the revegetation of these sites with native plants, is one such alternative. Revegetation often requires the addition of bulky amendments such as compost which greatly increases cost. We report the use of plant growth-promoting bacteria (PGPB) to enhance the revegetation of mine tailings and minimize the need for compost amendment. Twenty promising PGPB isolates were used as seed inoculants in a series of greenhouse studies to examine revegetation of an extremely acidic, high metal content tailings sample previously shown to require 15% compost amendment for normal plant growth. Several isolates significantly enhanced growth of two native species, quailbush and buffalo grass, in tailings. In this study, PGPB/compost outcomes were plant specific; for quailbush, PGPB were most effective in combination with 10% compost addition while for buffalo grass, PGPB enhanced growth in the complete absence of compost. Results indicate that selected PGPB can improve plant establishment and reduce the need for compost amendment. Further, PGPB activities necessary for aiding plant growth in mine tailings likely include tolerance to acidic pH and metals.

Green sulfur bacteria are considered to be amongst the most efficient light-harvesting organisms. Despite multiple experimental and theoretical studies of these bacteria the physical origin of the efficient and robust energy transfer in their light-harvesting complexes is not well understood.

Moreover, the same mechanism describes the coexistence of multiple timescales of excitation dynamics frequently observed in ultrafast optical experiments. While our findings support the hypothesis of supertransfer, the model reveals energy transport through multiple channels on different length scales.

Plutonium(V/VI) Reduction by the Metal-Reducing Bacteria  

E-Print Network (OSTI)

We examined the ability of the metal-reducing bacteria Geobacter metallireducens GS-15 and Shewanella oneidensis MR-1 to reduce Pu(VI) and Pu(V). Cell suspensions of both bacteria reduced oxidized Pu [a mixture of Pu(VI) and Pu(V)] to Pu(IV). The rate of plutonium reduction was similar to the rate of U(VI) reduction obtained under similar conditions for each bacteria. The rates of Pu(VI) and U(VI) reduction by cell suspensions of S. oneidensis were slightly higher than the rates observed with G. metallireducens. The reduced form of Pu was characterized as aggregates of nanoparticulates of Pu(IV). Transmission electron microscopy images of the solids obtained from the cultures after the reduction of Pu(VI) and Pu(V) by S. oneidensis show that the Pu precipitates have a crystalline structure. The nanoparticulates of Pu(IV) were precipitated on the surface of or within the cell walls of the bacteria. The production of Pu(III) was not observed, which indicates that Pu(IV) was the stable form of reduced Pu under these experimental conditions. Experiments examining the ability of these bacteria to use Pu(VI) as a terminal electron acceptor for growth were inconclusive. A slight increase in cell density was observed for both G. metallireducens and S. oneidensis when Pu(VI) was provided as the sole electron acceptor; however, Pu(VI) concentrations decreased similarly in both the experimental and control cultures.

Physiological diversity and distributions of heterotrophic bacteria in deep cretaceous sediments of the Atlantic coastal plain  

SciTech Connect

A series of 23 intact core segments was obtained from two distinct deep subsurface geological formations, the Middendorf and the Cape Fear formations, underlying the southeastern coastal plain of South Carolina. Aerobic chemoheterotrophic bacteria were enumerated on a dilute medium, and populations ranged from 3.1 to 6.4 log CFU g of sediment[sup [minus]1] in the Middendorf cores and from below detection to 4.3 log CFU g[sup [minus]1] in the Cape Fear cores. A total of 198 morphologically distinct colony types were isolated, purified, and subjected to 108 different physiological measurements. The isolates from the two formations were distinct as were those in different core samples from the same formation. Cluster analysis revealed 21 different biotypes based on similarities of 75% or higher in response patterns to 21 physiological assays. One biotype contained 57 of the subsurface isolates, 10 biotypes contained 5 or more isolates, and the remainder had 4 or fewer. The organic compounds that were most commonly metabolized by the subsurface bacteria included Tween 40 and [beta]-hydroxybutyric acid. Organic acids, in general, were also commonly metabolized by the subsurface bacteria. Isolates from the Cape Fear core segments were capable of metabolizing a higher percentage of the substrates than were bacteria isolated from the Middendorf formation. Although the heterogeneous distributions of bacteria in deep subsurface sediments may make it difficult to use aquifer microcosms to predict in situ biotransformation rates, the diversity of the physiological properties of these organisms offers promise for in situ remediation of contaminants.

Technique development for uiper critical field studies of SmFeAs(O,F) in the 300T single turn system  

SciTech Connect

In high temperature superconductors, such as the most recent class of iron pnictides, extremely high upper critical fields H{sub c2} are common. The determination of H{sub c2}(T) is crucial to understand the detailed nature of the superconductor, in particular H{sub c2}(T = 0K) is of great interest. It is not only related to fundamental properties of the system, it is furthermore of great importance for materials science, as it is the ultimate limit of applicability of this superconductor in high field applications. However, this important quantity can only be estimated by extrapolation, as H{sub c2}(T = 0K) well exceeds hundreds of Tesla in optimally doped SillFeAs(O,F). We are developing methods to measure Ha(T) in direct transport in the extreme magnetic fields generated by the LANL single turn magnet.

What Employees Need (and Want) to Hear When Justifying the Suspension of a Regulated Metals Plan for the Processing of Drums Containing Metal Turnings  

SciTech Connect

A Regulated Metals Plan (RMP) was implemented for outdoor work activities involving the removal and disposition of approximately 4,000 deteriorated waste drums containing 236 metric tonnes (260 tons) of lead turnings from various, unspecified machine shop facilities at the Paducah Gaseous Diffusion Plant. Until exposure monitoring could prove otherwise, the work area established for processing the drums was conservatively defined as a Lead Regulated Area (LRA) subject to the Occupational Safety and Health Administration's Lead Standard found in Title 29 of the Code of Federal Regulations, Part 1910.1025. The vast majority of the analytical results for the industrial hygiene breathing zone samples collected and tested for arsenic, beryllium, cadmium, chromium, lead, nickel, selenium, silver, and thallium using the National Institute for Occupational Safety and Health's analytical method 7300 were equivalent to the laboratory detection limits for each analyte. All results were less than 6% of their respective Permissible Exposure Limits (PEL), except for one nickel result that was approximately 17% of its PEL. The results provided justification to eventually down-post the LRA to existing employee protection requirements. In addition to removing the deteriorated drums and accompanying debris, the success of this project was quantified in terms of zero recordable injuries. The primary contributor in achieving this success was the sharing and communication of information between management, safety, and the field teams. Specifically, this was what the employees needed (and wanted) to hear when justifying the suspension of the RMP for the processing of drums containing metal turnings. Daily briefings on the status of the project and field monitoring results were just as important as maintaining budget and schedule milestones. Also, the Environmental, Safety and Health organization maintained its presence by continuing to monitor evolving field conditions to ensure the effectiveness of its plans and procedures. (authors)

Dysfunction of Organic Anion Transporting Polypeptide 1a1 Alters Intestinal Bacteria and Bile Acid Metabolism in Mice  

E-Print Network (OSTI)

Organic anion transporting polypeptide 1a1 (Oatp1a1) is predominantly expressed in liver and is able to transport bile acids (BAs) in vitro. Male Oatp1a1-null mice have increased concentrations of taurodeoxycholic acid (TDCA), a secondary BA generated by intestinal bacteria, in both serum and livers. Therefore, in the present study, BA concentrations and intestinal bacteria in wild-type (WT) and Oatp1a1-null mice were quantified to investigate whether the increase of secondary BAs in Oatp1a1-null mice is due to alterations in intestinal bacteria. The data demonstrate that Oatp1a1-null mice: (1) have similar bile flow and BA concentrations in bile as WT mice; (2) have a markedly different BA composition in the intestinal contents, with a decrease in conjugated BAs and an increase in unconjugated BAs; (3) have BAs in the feces that are more deconjugated, desulfated, 7-dehydroxylated, 3-epimerized, and oxidized, but less 7-epimerized; (4) have 10-fold more bacteria in the small intestine, and 2-fold more bacteria in the large intestine which is majorly due to a 200 % increase in Bacteroides and a 30 % reduction in Firmicutes; and (5) have a different urinary excretion of bacteria-related metabolites than WT mice. In conclusion, the present study for the first time established that lack of a liver transporter (Oatp1a1) markedly alters the intestinal environment in mice, namely the bacteria composition.

Biofuel from Bacteria and Sunlight: Shewanella as an Ideal Platform for Producing Hydrocarbons  

SciTech Connect

Broad Funding Opportunity Announcement Project: The University of Minnesota is developing clean-burning, liquid hydrocarbon fuels from bacteria. The University is finding ways to continuously harvest hydrocarbons from a type of bacteria called Shewanella by using a photosynthetic organism to constantly feed Shewanella the sugar it needs for energy and hydrocarbon production. The two organisms live and work together as a system. Using Shewanella to produce hydrocarbon fuels offers several advantages over traditional biofuel production methods. First, it eliminates many of the time-consuming and costly steps involved in growing plants and harvesting biomass. Second, hydrocarbon biofuels resemble current petroleum-based fuels and would therefore require few changes to the existing fuel refining and distribution infrastructure in the U.S.

Printed in Great Britain 107 The Decomposition of Toluene by Soil Bacteria  

E-Print Network (OSTI)

Strains of two bacteria, a Pseudomonas and an Achromobacter, which grow with toluene, benzene or certain other related aromatic compounds as sole carbon source were isolated from soil. The use of aromatic compounds by these bacteria was an induced phenomenon. Toluene-grown organisms oxidized without lag toluene, benzene, catechol, &methylcatechol, benzyl alcohol and, more slowly, o- and m-cresol, but not benzaldehyde or benzoic acid. 3-Methylcatechol, acetic acid, pyruvic acid, and a yellow ether-soluble acidic substance which was colourless in acid solution, were detected in toluene-oxidizing cultures. Acetic and pyruvic acids were also formed during the bacterial oxidation of 8-methylcatechol. 3-Methylcatechol is probably an early stage in the bacterial metabolism of toluene; benzaldehyde and benzoic acid seem not to be intermediates in this metabolism.

Diffusive transport without detailed balance in motile bacteria: Does microbiology need statistical physics?  

E-Print Network (OSTI)

Microbiology is the science of microbes, particularly bacteria. Many bacteria are motile: they are capable of self-propulsion. Among these, a significant class execute so-called run-and-tumble motion: they follow a fairly straight path for a certain distance, then abruptly change direction before repeating the process. This dynamics has something in common with Brownian motion (it is diffusive at large scales), and also something in contrast. Specifically, motility parameters such as the run speed and tumble rate depend on the local environment and hence can vary in space. When they do so, even if a steady state is reached, this is not generally invariant under time-reversal: the principle of detailed balance, which restores the microscopic time-reversal symmetry of systems in thermal equilibrium, is mesoscopically absent in motile bacteria. This lack of detailed balance (allowed by the flux of chemical energy that drives motility) creates pitfalls for the unwary modeller. Here I review some statistical mechanical models for bacterial motility, presenting them as a paradigm for exploring diffusion without detailed balance. I also discuss the extent to which statistical physics is useful in understanding real or potential microbiological experiments.

Design, testing and optimization of a microfluidic device for capture and concentration of bacteria  

E-Print Network (OSTI)

Effective detection of bacterial pathogens in large sample volumes is a challenging problem. Pre-concentration routines currently in practice before the actual detection process are cumbersome and hard to automate. An effort is made to address the problem of volume discrepancy between day-to-day samples and the concentrated samples needed for analysis. Principles of conceptual design are used in formulating the â??Need Statementâ??, â??Function Structureâ?? and in identifying the â??Critical Design Parametersâ?? and â??Design Constraintsâ??. Electrokinetic phenomena are used to exploit the surface charges on bacteria. Electrophoresis is used to transport the bacteria to electrode surface and â??Electrostatic trappingâ? is then used to capture these microbes on the electrode surface. The captured microbes can then be concentrated in a concentrator unit. A prototype microfluidic device is fabricated for showing the proof of concept. Optimization is done to minimize hydraulic power consumption and wetted volume. Observations from the initial prototype device along with the optimization results are used in building a new prototype device. Operation of this device is demonstrated by capture of bacteria from flow. Qualitative studies are conducted and preliminary quantification is also done.

The C-Terminal RpoN Domain of sigma54 Forms an unpredictedHelix-Turn-Helix Motif Similar to domains of sigma70  

SciTech Connect

The ''{delta}'' subunit of prokaryotic RNA-polymerase allows gene-specific transcription initiation. Two {sigma} families have been identified, {sigma}{sup 70} and {sigma}{sup 54}, which use distinct mechanisms to initiate transcription and share no detectable sequence homology. Although the {sigma}{sup 70}-type factors have been well characterized structurally by x-ray crystallography, no high-resolution structural information is available for the {sigma}{sup 54}-type factors. Here we present the NMR derived structure of the C-terminal domain of {sigma}{sup 54} from Aquifex aeolicus. This domain (Thr323 to Gly389), which contains the highly conserved RpoN box sequence, consists of a poorly structured N-terminal tail followed by a three-helix bundle, which is surprisingly similar to domains of the {sigma}{sup 70}-type proteins. Residues of the RpoN box, which have previously been shown to be critical for DNA binding, form the second helix of an unpredicted helix-turn-helix motif. This structure's homology with other DNA binding proteins, combined with previous biochemical data, suggest how the C-terminal domain of {sigma}{sup 54} binds to DNA.

Nano scale devices for plasmonic nanolithography and rapid sensing of bacteria  

E-Print Network (OSTI)

This dissertation contains two different research topics. One is a Nano Scale Device for Plasmonic Nanolithography Optical Antenna and the other is a Nano Scale Device for Rapid Sensing of Bacteria SEPTIC. Since these two different research topics have little analogy to each other, they were divided into different chapters throughout the whole dissertation. The Optical Antenna and Nanowell / Microwell / ISFET Sensor represent the device names of each topic Plasmonic Nanolithography and Rapid Sensing of Bacteria, respectively. For plasmonic nanolithography, we demonstrated a novel photonic device - Optical Antenna (OA) - that works as a nano scale object lens. It consists of a number of sub-wavelength features in a metal film coated on a quartz substrate. The device focuses the incident light to form a narrow beam in the near-field and even far-field region. The narrow beam lasts for up to several wavelengths before it diverges. We demonstrated that the OA was able to focus a subwavelength spot with a working distance (also the focal length) of several m, theoretically and experimentally. The highest imaging resolution (90-nm spots) is more than a 100% improvement of the diffraction limit (FWHM = 210 nm) in conventional optics. A model and 3D electromagnetic simulation results were also studied. Given its small footprint and subwavelength resolution, the PL holds great promise in direct-writing and scanning microscopy. Collaborative work demonstrated a Nanowell (or Microwell) device which enables a rapid and specific detection of bacteria using nano (or micro) scale probe to monitor the electric field fluctuations caused by ion leakage from the bacteria. When a bacteriophage infects a bacterium and injects its DNA into the host cell, a massive and transitory ion efflux from the host cell occurs. SEPTIC (SEnsing of Phage-Triggered Ion Cascade) technology developed by collaboration uses a nanowell device to detect the nano-scale electric field fluctuations caused by this ion efflux. The SEPTIC provides fast (within several minutes), effective (living cell only), phage specific (simple and less malfunction), cheap, compact and robust method for bacteria sensing. We fabricated a number of devices, including Nanowell, Microwell, and ISFET (Ion Selective Field Effect Transistor), which detect bacteria-phage reactions in frequency domain and time domain. In the frequency domain, detected noise spectrum is characterized by ? f / 1 . The positive reaction showed much higher 1 ? ? than that of background noise or negative reaction ( 0 ? ? ). For the time domain, we observed abnormal pulses (> ? 8 ) lasting 0.1 ~ 0.3 s which match the duration of ion flux reported by prior literatures. And the ISFET showed the phage-infection-triggered pulse in the form of the deviated drain current. Given the size of nanowell (or microwell, ISFET) and the simplified detection electronics, the cost of bacteria sensing is significantly reduced and the robustness is well improved, indicating very promising applications in clinical diagnosis and bio-defense.

MOLECULAR APPROACHES FOR IN SITU IDENTIFCIATION OF NITRATE UTILIZATION BY MARINE BACTERIA AND PHYTOPLANKTON  

SciTech Connect

Traditionally, the importance of inorganic nitrogen (N) for the nutrition and growth of marine phytoplankton has been recognized, while inorganic N utilization by bacteria has received less attention. Likewise, organic N has been thought to be important for heterotrophic organisms but not for phytoplankton. However, accumulating evidence suggests that bacteria compete with phytoplankton for nitrate (NO3-) and other N species. The consequences of this competition may have a profound effect on the flux of N, and therefore carbon (C), in ocean margins. Because it has been difficult to differentiate between N uptake by heterotrophic bacterioplankton versus autotrophic phytoplankton, the processes that control N utilization, and the consequences of these competitive interactions, have traditionally been difficult to study. Significant bacterial utilization of DIN may have a profound effect on the flux of N and C in the water column because sinks for dissolved N that do not incorporate inorganic C represent mechanisms that reduce the atmospheric CO2 drawdown via the ?biological pump? and limit the flux of POC from the euphotic zone. This project was active over the period of 1998-2007 with support from the DOE Biotechnology Investigations ? Ocean Margins Program (BI-OMP). Over this period we developed a tool kit of molecular methods (PCR, RT-PCR, Q-PCR, QRT-PCR, and TRFLP) and combined isotope mass spectrometry and flow-cytometric approaches that allow selective isolation, characterization, and study of the diversity and genetic expression (mRNA) of the structural gene responsible for the assimilation of NO3- by heterotrophic bacteria (nasA). As a result of these studies we discovered that bacteria capable of assimilating NO3- are ubiquitous in marine waters, that the nasA gene is expressed in these environments, that heterotrophic bacteria can account for a significant fraction of total DIN uptake in different ocean margin systems, that the expression of nasA is differentially regulated in genetically distinct NO3- assimilating bacteria, and that the best predictors of nasA gene expression are either NO3- concentration or NO3- uptake rates. These studies provide convincing evidence of the importance of bacterial utilization of NO3-, insight into controlling processes, and provide a rich dataset that are being used to develop linked C and N modeling components necessary to evaluate the significance of bacterial DIN utilization to global C cycling. Furthermore, as a result of BI-OMP funding we made exciting strides towards institutionalizing a research and education based collaboration between the Skidaway Institute of Oceanography (SkIO) and Savannah State University (SSU), an historically black university within the University System of Georgia with undergraduate and now graduate programs in marine science. The BI-OMP program, in addition to supporting undergraduate (24) graduate (10) and postdoctoral (2) students, contributed to the development of a new graduate program in Marine Sciences at SSU that remains an important legacy of this project. The long-term goals of these collaborations are to increase the capacity for marine biotechnology research and to increase representation of minorities in marine, environmental and biotechnological sciences.

Laser Ablation of Organic Materials for discrimination of bacteria in an Laser Ablation of Organic Materials for discrimination of bacteria in an organic background Title Laser Ablation of Organic Materials for discrimination of bacteria in an organic background Publication Type Conference Proceedings Year of Publication 2009 Authors Baudelet, Matthieu, Myriam Boueri, Jin Yu, Xianglei Mao, Samuel S. Mao, and Richard E. Russo Conference Name Ultrafast Phenomena in Semiconductors and Nanostructure Materials XIII Series Title Proceedings SPIE Volume 7214 Pagination 72140J Date Published 02/2009 Abstract We demonstrate in this paper that laser ablation allows efficient analysis of organic and biological materials. Such analysis is based on laser-induced breakdown spectroscopy (LIBS) which consists in the detection of the optical emission from the plasma induced by a high intensity laser pulse focused on the sample surface. The optimization of the ablation regime in terms of laser parameters (pulse duration, wavelength, fluence) is important to generate a plasma suitable for the analysis. We first present the results of a study of laser ablation of organic samples with different laser parameters using time-resolved shadowgraph. We correlate the early stage expansion of the plasma to its optical emission properties, which allows us to choose suitable laser parameters for an efficient analysis of organic or biological samples by LIBS. As an illustration of the analytical ability of LIBS for biological materials, we show that the emission from CN molecules can be used to distinguish between biological and inorganic samples. Native CN molecular fragment directly ablated from a biological sample are identified using time-resolved LIBS. Those due to recombination with nitrogen contained in atmospheric air can be distinguished with their specific time evolution behavior.

Exploration of Simple Analytical Approaches for Rapid Detection of Pathogenic Bacteria  

Science Conference Proceedings (OSTI)

Many of the current methods for pathogenic bacterial detection require long sample-preparation and analysis time, as well as complex instrumentation. This dissertation explores simple analytical approaches (e.g., flow cytometry and diffuse reflectance spectroscopy) that may be applied towards ideal requirements of a microbial detection system, through method and instrumentation development, and by the creation and characterization of immunosensing platforms. This dissertation is organized into six sections. In the general Introduction section a literature review on several of the key aspects of this work is presented. First, different approaches for detection of pathogenic bacteria will be reviewed, with a comparison of the relative strengths and weaknesses of each approach, A general overview regarding diffuse reflectance spectroscopy is then presented. Next, the structure and function of self-assembled monolayers (SAMs) formed from organosulfur molecules at gold and micrometer and sub-micrometer patterning of biomolecules using SAMs will be discussed. This section is followed by four research chapters, presented as separate manuscripts. Chapter 1 describes the efforts and challenges towards the creation of imunosensing platforms that exploit the flexibility and structural stability of SAMs of thiols at gold. 1H, 1H, 2H, 2H-perfluorodecyl-1-thiol SAM (PFDT) and dithio-bis(succinimidyl propionate)-(DSP)-derived SAMs were used to construct the platform. Chapter 2 describes the characterization of the PFDT- and DSP-derived SAMs, and the architectures formed when it is coupled to antibodies as well as target bacteria. These studies used infrared reflection spectroscopy (IRS), X-ray photoelectron spectroscopy (XPS), and electrochemical quartz crystal microbalance (EQCM), Chapter 3 presents a new sensitive, and portable diffuse reflection based technique for the rapid identification and quantification of pathogenic bacteria. Chapter 4 reports research efforts in the construction and evaluation of a prototype flow cytometry based cell detector and enumerator. This final research chapter is followed by a general summation and future prospectus section that concludes this dissertation.

Light-harvesting in bacteria exploits a critical interplay between transport and trapping dynamics  

E-Print Network (OSTI)

Light-harvesting bacteria Rhodospirillum Photometricum were recently found to adopt strikingly different architectures depending on illumination conditions. We present analytic and numerical calculations which explain this observation by quantifying a dynamical interplay between excitation transfer kinetics and reaction center cycling. High light-intensity membranes (HLIM) exploit dissipation as a photo-protective mechanism, thereby safeguarding a steady supply of chemical energy, while low light-intensity membranes (LLIM) efficiently process unused illumination intensity by channelling it to open reaction centers. More generally, our analysis elucidates and quantifies the trade-offs in natural network design for solar energy conversion.

Structural similarities between biogenic uraninites produced by phylogenetically and metabolically diverse bacteria.  

SciTech Connect

While the product of microbial uranium reduction is often reported to beUO2, a comprehensive characterization including stoichiometry and unit cell determination is available for only one Shewanella species. Here, we compare the products of batch uranyl reduction by a collection of dissimilatory metal- and sulfate-reducing bacteria of the genera Shewanella, Geobacter, Anaeromyxobacter, and Desulfovibrio under similar laboratory conditions. Our results demonstrate that U(VI) bioreduction by this assortment of commonly studied, environmentally relevant bacteria leads to the precipitation of uraninite with a composition between UO2.00 and UO2.075, regardless of phylogenetic or metabolic diversity. Coupled analyses, including electron microscopy, X-ray absorption spectroscopy, and powder diffraction, confirm that structurally and chemically analogous uraninite solids are produced. These biogenic uraninites have particle diameters of about 2-3 nm and lattice constants consistent with UO2.0 and exhibit a high degree of intermediate-range order. Results indicate that phylogenetic and metabolic variability within delta- and gamma-proteobacteria has little effect on nascent biouraninite structure or crystal size under the investigated conditions.

Influence of gamma irradiation on the metabolic activity of sulfate-reducing bacteria  

SciTech Connect

When water is pumped into oil-bearing seams to increase oil production, the microorganisms in the injected water fall into favorable ecological conditions and, quickly adapting, form a biocenosis and begin to actively develop. Among the anaerobic microorganisms, the most hazardous from the corrosion viewpoint are the sulfate-reducing bacteria (SRB), which are the main producers of hydrogen sulfide as the product of anaerobic respiration. This paper reports on the effect of gamma rays on the metabolic study of SRB Desulfovibrio desulfuricans in the nutrient medium Postgate B. The radioactive source used is a /sup 60/CoK-125 unit with a power of 700 rad/sec. The required dose of gamma rays was calculated from the exposure times of samples with the test medium in the radiation zone o the isotope /sup 60/Co. The criterion characterizing the effectiveness of suppression of development of the bacteria is the concentration of biogenic hydrogen sulfide produced, as determined by iodometric titration.

Structure, Function and Reconstitution of Antenna Complexes of Green Photosynthetic Bacteria  

DOE Green Energy (OSTI)

Most chlorophyll-type pigments in a photosynthetic organism function as an antenna, absorbing light and transferring excitations to a photochemical reaction center where energy storage takes place by a series of chemical reactions. The green photosynthetic bacteria are characterized by large antenna complexes known as chlorosomes, in which pigment-pigment interactions are of dominant importance. The overall objective of this project is to determine the mechanisms of excitation transfer and regulation of this unique antenna system, including how it is integrated into the rest of the photosynthetic energy transduction apparatus. Techniques that are being used in this research include biochemical analysis, spectroscopy, microscopy, X-ray structural studies, and reconstitution from purified components. Our recent results indicate that the chlorosome baseplate structure, which is the membrane attachment site for the chlorosome to the membrane, is a unique pigment-protein that contains large amounts of carotenoids and small amounts of bacteriochlorophyll a. Reconstitution of directed energy transfer in chlorosomes will be carried out using purified baseplates and oligomeric pigments. The integral membrane B808-866 antenna complex from Chloroflexus aurantiacus and the Fenna-Matthews-Olson protein-reaction center complex from green sulfur bacteria will be characterized by spectroscopic and structural techniques.

Roles of Naturally Occurring Bacteria in Controlling Iodine-129 Mobility in Subsurface Soils  

E-Print Network (OSTI)

129I is of major concern because of its biophilic nature, excessive inventory, long half-life (~16 million yrs), and high mobility in the natural environment that depends on its chemical speciation. Iodide (I-) has the highest mobility than iodate (IO3-) and is the predominant species in the terrestrial environment due to prevailing pH and Eh conditions. In order to transform I- to less mobile organo-iodine (OI), strong oxidants are necessary to activate the first electron transfer step from I- to reactive intermediates. The aim of this study was to determine the influence of naturally occurring aerobic bacteria isolated from an 129I contaminated aquifer (F-area of the Savannah River Site, SC) on I- oxidation and OI formation. It was demonstrated that 3 of 136 strains accumulated I- (0.2~2%) in the presence of H2O2, when incubated in the presence of an environmentally relevant concentration of I- (0.1 microM). The accumulation was likely through electrophilic substitution resulting in the iodination of cellular constituents. The results indicated that culturable I--accumulating bacteria are not directly responsible for the high fraction of oxidized iodine species (IO3- and OI, >50% of total I) present in the SRS F-area. Several bacterial strains were found to be capable of stimulating I- oxidation through excretion of oxidants and enzymes. Organic acids in spent liquid medium from 27 of 84 aerobic bacterial cultures enhanced H2O2-dependent I- oxidation 2-10 fold. Organic acids enhanced I- oxidation by (1) lowering the pH of the spent medium and (2) reacting with H2O2 to form peroxy carboxylic acids, which are strong oxidizing agents. In the absence of H2O2, spent medium from 44 of 84 bacteria cultures showed I- oxidizing capacities. One I- oxidizing bacterium was studied to characterize its extracellular I- oxidizing component(s). The I- oxidizing capability from the spent medium was inactive by treatments with heat and H2O2 and absent under anaerobic conditions. Conversely, NADH, NADPH and FMN additions stimulated I- oxidation in the spend medium. These results indicate an oxidase(s) catalyzed I- oxidation. Understanding the bacterial activities involved with I- oxidation and OI formation is expected to help reduce 129I mobility in water-soil systems.

Antenna organization in green photosynthetic bacteria. Progress report, July 1, 1985--June 30, 1987  

DOE Green Energy (OSTI)

This project is concerned with the structure and function of the unique antenna system found in the green photosynthetic bacteria. The antenna system in these organisms is contained within a vesicle known as a chlorosome, which is attached to the cytoplasmic side of the cell membrane. Additional antenna pigments and reaction centers are contained in integral membrane proteins. Energy absorbed by the bacteriochlorophyll c (BChl c) pigments in the chlorosome is transferred via a ``baseplate`` array of BChl a antenna pigments into the membrane and to the reaction center. A schematic model of chlorosome structure is shown. This project is aimed at increasing our understanding of the organization of the pigments in the chlorosome and how the antenna system functions.

3rd ASM Conference on Cell-Cell Communication in Bacteria  

Science Conference Proceedings (OSTI)

This report summarizes the final program and provides the abstracts presented at the fourth American Society of Microbiology-sponsored conference on Cell-cell Communication in Bacteria, held November 6-9, 2011 in Miami, Florida. Bacteria are the paradigm for unicellular life, yet they also exhibit elaborate coordinated behaviors that often defy unicellularity. Research over the past two decades has revealed that a wide range of microbes communicate by diverse mechanisms. In most cases these microbial conversations occur through the exchange of diffusible signals, although there are also clear examples of contact-dependent communication. Many microbes use these signaling mechanisms to monitor and respond to population density, a process often described as quorum sensing. Interbacterial communication is not, however restricted to quorum sensing mechanisms, and there is mounting evidence that signaling can function in a range of different capacities. Communication between microorganisms has profound impacts on host interactions, as pathogens and commensals often regulate factors critical for interaction with their hosts via signal production and perception. The CCCB-4 conference provided a unique forum for the discussion, dissemination and exchange of new information and ideas among researchers working within this rapidly developing, yet mature field. Sessions were arranged around topics such as: the diversity of signal generation and identity; mechanisms of signal transduction and interference; cell-cell communication in bacterial development and antibiotic synthesis; host-microbe signaling and pathogenesis; symbiosis, mutualism, and microbe-microbe communication; ecology and evolution; advancements in the technological tool-kit for studying cell-cell communication. The conference served as a conduit for the exchange and synthesis of new ideas among leading US and international scientists working on bacterial communication.

Excitonic energy transfer in light-harvesting complexes in purple bacteria  

Science Conference Proceedings (OSTI)

Two distinct approaches, the Frenkel-Dirac time-dependent variation and the Haken-Strobl model, are adopted to study energy transfer dynamics in single-ring and double-ring light-harvesting (LH) systems in purple bacteria. It is found that the inclusion of long-range dipolar interactions in the two methods results in significant increase in intra- or inter-ring exciton transfer efficiency. The dependence of exciton transfer efficiency on trapping positions on single rings of LH2 (B850) and LH1 is similar to that in toy models with nearest-neighbor coupling only. However, owing to the symmetry breaking caused by the dimerization of BChls and dipolar couplings, such dependence has been largely suppressed. In the studies of coupled-ring systems, both methods reveal an interesting role of dipolar interactions in increasing energy transfer efficiency by introducing multiple intra/inter-ring transfer paths. Importantly, the time scale (4 ps) of inter-ring exciton transfer obtained from polaron dynamics is in good agreement with previous studies. In a double-ring LH2 system, non-nearest neighbor interactions can induce symmetry breaking, which leads to global and local minima of the average trapping time in the presence of a non-zero dephasing rate, suggesting that environment dephasing helps preserve quantum coherent energy transfer when the perfect circular symmetry in the hypothetic system is broken. This study reveals that dipolar coupling between chromophores may play an important role in the high energy transfer efficiency in the LH systems of purple bacteria and many other natural photosynthetic systems.

Determination of kinetic coefficients for the simultaneous reduction of sulfate and uranium by Desulfovibrio desulfuricans bacteria  

Science Conference Proceedings (OSTI)

Uranium contamination of groundwaters and surface waters near abandoned mill tailings piles is a serious concern in many areas of the western United States. Uranium usually exists in either the U(IV) or the U(VI) oxidation state. U(VI) is soluble in water and, as a result, is very mobile in the environment. U(IV), however, is generally insoluble in water and, therefore, is not subject to aqueous transport. In recent years, researchers have discovered that certain anaerobic microorganisms, such as the sulfate-reducing bacteria Desulfovibrio desulfuricans, can mediate the reduction of U(VI) to U(IV). Although the ability of this microorganism to reduce U(VI) has been studied in some detail by previous researchers, the kinetics of the reactions have not been characterized. The purpose of this research was to perform kinetic studies on Desulfovibrio desulficans bacteria during simultaneous reduction of sulfate and uranium and to determine the phase in which uranium exists after it has been reduced and precipitated from solution. The studies were conducted in a laboratory-scale chemostat under substrate-limited growth conditions with pyruvate as the substrate. Kinetic coefficients for substrate utilization and cell growth were calculated using the Monod equation. The maximum rate of substrate utilization (k) was determined to be 4.70 days{sup {minus}1} while the half-velocity constant (K{sub s}) was 140 mg/l COD. The yield coefficient (Y) was determined to be 0.17 mg cells/mg COD while the endogenous decay coefficient (k{sub d}) was calculated as 0.072 days{sup {minus}1}. After reduction, U(IV) Precipitated from solution in the uraninite (UO{sub 2}) phase. Uranium removal efficiency as high as 90% was achieved in the chemostat.

Mtr Extracellular Electron Transfer Pathways in Fe(III)-reducing or Fe(II)-oxidizing Bacteria: A Genomic Perspective  

Science Conference Proceedings (OSTI)

Originally discovered in the dissimilatory metal-reducing bacterium Shewanella oneidensis MR-1 (MR-1), the Mtr (i.e., metal-reducing) pathway exists in all characterized strains of metal-reducing Shewanella. The protein components identified to date for the Mtr pathway of MR-1 include four multi-heme c-type cytochromes (c-Cyts), CymA, MtrA, MtrC and OmcA, and a porin-like, outer membrane protein MtrB. They are strategically positioned along the width of the MR-1 cell envelope to mediate electron transfer from the quinone/quinol pool in the inner-membrane to the Fe(III)-containing minerals external to the bacterial cells. A survey of microbial genomes revealed homologues of the Mtr pathway in other dissimilatory Fe(III)-reducing bacteria, including Aeromonas hydrophila, Ferrimonas balearica and Rhodoferax ferrireducens, and in the Fe(II)-oxidizing bacteria Dechloromonas aromatica RCB, Gallionella capsiferriformans ES-2 and Sideroxydans lithotrophicus ES-1. The widespread distribution of Mtr pathways in Fe(III)-reducing or Fe(II)-oxidizing bacteria emphasizes the importance of this type of extracellular electron transfer pathway in microbial redox transformation of Fe. Their distribution in these two different functional groups of bacteria also emphasizes the bi-directional nature of electron transfer reactions carried out by the Mtr pathways. The characteristics of the Mtr pathways may be shared by other pathways used by microorganisms for exchanging electrons with their extracellular environments.

Quantification of syntrophic fatty acid-{beta}-oxidizing bacteria in a mesophilic biogas reactor by oligonucleotide probe hybridization  

Science Conference Proceedings (OSTI)

Small-subunit rRNA sequences were obtained for two saturated fatty acid-{beta}-oxidizing syntrophic bacteria, Syntrophomonas sapovorans and Syntrophomonas wolfei LYB, and sequence analysis confirmed their classification as members of the family Syntrophomonadaceae. S.wolfei LYB was closely related to S.wolfei subsp. solfei, but S. sapovorans did not cluster with the other members of the genus Syntrophomonas. Five oligonucleotide probes targeting the small-subunit rRNA of different groups within the family Syntrophomonadaceae, which contains all currently known saturated fatty acid-{beta}-oxidizing syntrophic bacteria, were developed and characterized. The probes were designed to be specific at the family, genus, and species levels and were characterized by temperature-of-dissociation and specificity studies. To demonstrate the usefulness of the probes for the detection and quantification of saturated fatty acid-{beta}-oxidizing syntrophic bacteria in methanogenic environments, the microbial community structure of a sample from a full-scale biogas plant was determined. Hybridization results with probes for syntrophic bacteria and methanogens were compared to specific methanogenic activities and microbial numbers determined with most-probable-number estimates. Most of the methanogenic rRNA was comprised of Methanomicrobiales rRNA, suggesting that members of this order served as the main hydrogen-utilizing microorganisms. Between 0.2 and 1% of the rRNA was attributed to the Syntrophomonadaceae, or which the majority was accounted for by the genus Syntrophomonas.

Novel Thermo-Acidophilic Bacteria Isolated from Geothermal Sites in Yellowstone National Park: Physiological and Phylogenetic Characteristics  

Science Conference Proceedings (OSTI)

Moderately thermophilic acidophilic bacteria were isolated from geothermal (3083 C) acidic (pH 2.7 3.7) sites in Yellowstone National Park. The temperature maxima and pH minima of the isolates ranged from 50 to 65 C, and pH 1.01.9. Eight of the bacteria were able to catalyze the dissimilatory oxidation of ferrous iron, and eleven could reduce ferric iron to ferrous iron in anaerobic cultures. Several of the isolates could also oxidize tetrathionate. Six of the iron-oxidizing isolates, and one obligate heterotroph, were low G+C gram-positive bacteria (Firmicutes). The former included three Sulfobacillus-like isolates (two closely related to a previously isolated Yellowstone strain, and the third to a mesophilic bacterium isolated from Montserrat), while the other three appeared to belong to a different genus. The other two iron-oxidizers were an Actinobacterium (related to Acidimicrobium ferrooxidans) and a Methylobacterium-like isolate (a genus within the a-Proteobacteria that has not previously been found to contain either iron-oxidizers or acidophiles). The other three (heterotrophic) isolates were also a-Proteobacteria and appeared be a novel thermophilic Acidisphaera sp. An ARDREA protocol was developed to discriminate between the iron-oxidizing isolates. Digestion of amplified rRNA genes with two restriction enzymes (SnaBI and BsaAI) separated these bacteria into five distinct groups; this result was confirmed by analysis of sequenced rRNA genes.

Occurrence, Prevalence, and Disinfection Potential of Tetracycline Resistance Genes and Tetracycline Resistant Bacteria in a Subtropical Watershed  

E-Print Network (OSTI)

Antibiotics are an important method for protecting human health. Unfortunately, the development of antibiotic resistance has decreased the effectiveness of antibiotics in treating disease and preventing deaths associated with bacterial infection. The objective of this dissertation research was to gain a better understanding of anthropogenic influences on occurrence of tetracycline resistance and use of traditional disinfection methods for the reduction of tetracycline resistant bacteria and genes. Culture based and molecular methods were used to evaluate the occurrence of tetracycline resistance in a rapidly urbanizing watershed, identify the dominant resistant organisms and resistance genes in the watershed, and evaluate the use of UV and chlorine to reduce the concentration of resistant bacteria and resistance genes. Results from this research showed that tetracycline resistance was prevalent and is maintained in this study area. Several bacterial species (Aeromonas, Acinetobacter, Chryseobacterium, E. coli, Pseudomonas, and Serratia) made up the resistant population. The results also indicated that tet(W) was the major resistance gene in this watershed and that a majority of the resistant bacteria were capable of transferring their resistance. Landuse did not cause a difference in occurrence of resistant bacteria or resistance genes which suggests that a rapidly urbanizing watershed could experience resistance. It was also identified that environmental media (sediment and water) influence the occurrence and prevalence of resistant bacteria and resistance genes. The results indicate that streambed sediment may act as a reservoir for resistance and resistance might be transported in the water. Finally, the results showed that neither UV nor chlorine disinfection were effective in reducing tet(W) concentrations though the results varied greatly among species. Results from this research indicate that preventing the occurrence and distribution of resistance gene in the environment is difficult, and resistance will most likely be maintained. Therefore, in order to prevent the spread of antibiotic resistance, it will be important to prevent antibiotic resistance from becoming established in the environment. This can be done by educating the public about the importance of misusing and mismanaging antibiotics. Additionally, classifying antibiotics for either human or veterinary use may help slow the development of resistance. This should prevent clinically important antibiotics from being used in sub-therapeutic doses, which could decrease the selective pressure in the environment. Also clinically relevant bacteria can be prevented from interacting with resistant bacteria in the environment by disinfecting human waste.

Structure, Function and Reconstitution of Antenna Complexes from Green Photosynthetic Bacteria  

DOE Green Energy (OSTI)

This project is concerned with the structure and function of the chlorosome antennas found in green photosynthetic bacteria. Chlorosomes are ellipsoidal structures attached to the cytoplasmic side of the inner cell membrane. These antenna complexes provide a very large absorption cross section for light capture. Evidence is overwhelming that the chlorosome represents a very different type of antenna from that found in any other photosynthetic system yet studied. It is now clear that chlorosomes do not contain traditional pigment-proteins, in which the pigments bind to specific sites on proteins. Instead, the chlorosome pigments are organized in vivo into pigment oligomers in which direct pigment-pigment interactions are of dominant importance. Our group has used a multidisciplinary approach to investigate this unique system, as well as the complexes that they directly interact with. Our work has included using model systems, numerous types of both steady-state and ultrafast spectroscopy, molecular biology, protein chemistry and X-ray crystallography. Details of our recent results using these approaches are given below and in the references. Numbers cited in the sections refer to DOE-sponsored publications that are listed below. Only publications dated 2001-2004 or later are included in this report. In addition to the primary literature reports, a comprehensive review of this area of research has been written as well as a commentary.

Reduction and Immobilization of Radionuclides and Toxic Metal Ions Using Combined Zero Valent Iron and Anaerobic Bacteria  

Science Conference Proceedings (OSTI)

The use of zero valent iron, permeable reactive barriers (PRBs) for groundwater remediation continues to increase. AN exciting variation of this technology involves introducing anaerobic bacteria into these barriers so that both biological and abiotic pollutant removal processes are functional. This work evaluated the hypothesis that a system combining a mixed culture of sulfate reducing bacteria (SRB) with zero valent iron would have a greater cr(VI) removal efficiency and a greater total Cr(VI) removal capacity than a zero valent iron system without the microorganisms. Hence, the overall goal of this research was to compare the performance of these types of systems with regard to their Cr(VI) removal efficiency and total Cr(VI) removal capacity. Both batch and continuous flow reactor systems were evaluated.

Pitting corrosion behavior of 316L stainless steel in the media of sulphate-reducing and iron-oxidizing bacteria  

SciTech Connect

Pitting corrosion behavior of 316L SS was investigated in the presence of aerobic and anaerobic bacteria isolated from cooling water system in oil refinery using polarization measurement, electrochemical impedance spectroscopy, scanning electron microscopy examinations and energy dispersive spectrum analysis. The results show the corrosion potential (E{sub corr}), pitting potential (E{sub pit}) and polarization resistance (R{sub P}) of 316L SS had a distinct decrease in the presence of bacteria, in comparison with those observed in the sterile medium for the same exposure time interval. Micrometer-scale pitting was observed on the 316L SS surface in the presence of bacteria. The combination of SRB and IOB demonstrated higher corrosion rates than SRB or IOB alone. The synergy of 0.01 M NaCl + SRB + IOB yielded the highest corrosion rate. The synergies between the metal surface, abiotic corrosion products, chloride anion, and bacterial cells and their metabolic products increased the corrosion damage degree of the passive film and accelerated pitting propagation.

Relevance of the photosynthetic reaction center from purple bacteria to the structure of photosystem II  

SciTech Connect

Photosynthetic organisms are able to oxidize organic or inorganic compounds upon the absorption of light, and they use the extracted electron for the fixation of carbon dioxide. The most important oxidation product is oxygen due to the splitting of water. In eukaryotes these processes occur in photosystem II of chloroplasts. Among prokaryotes photosynthetic oxygen evolution is restricted to cyanobacteria and prochloron-type organisms. How water is split in the oxygen-evolving complex of photosystem II belongs to the most important question to be answered. The primary charge separation occurs in the reaction center of photosystem II. This reaction center is a complex consisting of peripheral and integral membrane proteins, several chlorophyll A molecules, two pheophytin A molecules, two and three plastoquinone molecules, and one non-heme iron atom. The location of the photosystem II reaction center is still a matter of debate. Nakatani et al. (l984) concluded from fluorescence measurements that a protein of apparent molecular weight 47,000 (CP47) is the apoprotein of the photosystem II reaction center. A different view emerged from work with the photosynthetic reaction centers from the purple bacteria. The amino acid sequence of the M subunit of the reaction center from Phodopseudomonas (Rps.) sphaeroides has sequence homologies with the D1 protein from spinach. A substantial amount of structural information can be obtained with the reaction center from Rhodopseudomonas viridis, which can be crystallized. Here the authors discuss the structure of the photosynthetic reaction center from the purple bacterium Rps. viridis and describe the role of those amino acids that are conserved between the bacterial and photosystem II reaction center.

Electron spin polarization of the oxidized primary electron donor in reaction centers of photosynthetic purple bacteria  

SciTech Connect

Fast time-resolved EPR spectroscopy is used to study electron spin polarization (ESP) in perdeuterated native, Fe{sup 2+}-containing reaction centers (RCs) of photosynthetic purple bacteria. The spin-correlated radical pair-(SCRP) model previously used to simulate ESP observed in Fe-depleted RCs is extended to include the large anisotropy arising from the magnetic interactions between Fe{sup 2+} and the reduced primary electron-acceptor quinone (Q{sub A}{sup .-}), which results in different quantization axes from the P{sup .+} and the (Q{sub A}{sup .-}Fe{sup 2+}) spins. Using spectral simulations, it is shown that the ESP spectrum is solely due to the P{sup .+} part of the spin-correlated radical pair [P{sup .+}(Q{sub A}{sup .-}Fe{sup 2+})], whereas the rapid decay of the spin-polarized signal is due to spin-lattice relaxation of the (Q{sub A}{sup .-}Fe{sup 2+}) complex. The simulations are very sensitive to the relative orientation of the g matrices of P{sup .+} and (Q{sub A}{sup .-}Fe{sup 2+}). Using orientation II of the g matrix of the oxidized primary donor P{sup .+}, the orientation of the g matrix of (Q{sub A}{sup .-}Fe{sup 2+}) is assessed. Finally, it is shown that the ESP spectrum of perdeuterated native, Fe{sup 2+}-containing RCs of Rhodopseudomonas (Rps) viridis is virtually identical to the spectrum obtained for perdeuterated native Rhodobacter (Rb.) sphaeroides. 55 refs., 5 figs., 4 tabs.

Estimating Bacteria Emissions from Inversion of Atmospheric Transport: Sensitivity to Modelled Particle Characteristics  

SciTech Connect

Model-simulated transport of atmospheric trace components can be combined with observed concentrations to obtain estimates of ground-based sources using various inversion techniques. These approaches have been applied in the past primarily to obtain source estimates for long-lived trace gases such as CO2. We consider the application of similar techniques to source estimation for atmospheric aerosols, by using as a case study the estimation of bacteria emissions from different ecosystem regions in the global atmospheric chemistry and climate model ECHAM5/MESSy-Atmospheric Chemistry (EMAC). Simulated particle concentrations in the tropopause region and at high latitudes, as well as transport of particles to tundra and land ice regions are shown to be highly sensitive to scavenging in mixed-phase clouds, which is poorly characterized in most global climate models. This may be a critical uncertainty in correctly simulating the transport of aerosol particles to the Arctic. Source estimation via Monte Carlo Markov Chain is applied to a suite of sensitivity simulations and the global mean emissions are estimated. We present an analysis of the partitioning of uncertainties in the global mean emissions that are attributable to particle size, CCN activity, the ice nucleation scavenging ratios for mixed-phase and cold clouds, and measurement error. Uncertainty due to CCN activity or to a 1 um error in particle size is typically between 10% and 40% of the uncertainty due to data uncertainty, as measured by the 5%-ile to 95%-ile range of the Monte Carlo ensemble. Uncertainty attributable to the ice nucleation scavenging ratio in mized-phase clouds is as high as 10% to 20% of the data uncertainty. Taken together, the four model 20 parameters examined contribute about half as much to the uncertainty in the estimated emissions as do the measurements. This was a surprisingly large contribution from model uncertainty in light of the substantial data uncertainty, which ranges from 81% to 870% for each of ten ecosystems for this case study. The effects of these and other model parameters in contributing to the uncertainties in the transport of atmospheric aerosol particles should be treated explicitly and systematically in both forward and inverse modelling studies.

The Silicon Solar Cell Turns 50  

NLE Websites -- All DOE Office Websites (Extended Search)

Daryl Chapin, Calvin Fuller, and Gerald Daryl Chapin, Calvin Fuller, and Gerald Pearson likely never imagined inventing a solar cell that would revolutionize the photovoltaics industry. There wasn't even a photovoltaics industry to revolu- tionize in 1952. The three scientists were simply trying to solve problems within the Bell tele- phone system. Traditional dry cell batteries, which worked fine in mild climates, degraded too rapidly in the tropics and ceased to work when needed. The company therefore asked its famous research arm-Bell Laboratories-to explore alternative sources of freestand- ing power. Daryl Chapin got the assign- ment. At that time, his job was to test wind machines, thermoelectric gensets, and steam engines. Being a solar energy enthusiast, he suggested that the investi- gation include solar cells. His supervisor

Nuclear energy at the turning point  

DOE Green Energy (OSTI)

In deciding the future course of nuclear energy, it is necessary to re-examine man's long-term energy options, in particular solar energy and the breeder reactor. Both systems pose difficultiies: energy from the sun is likely to be expensive as well as limited, whereas a massive world-wide deployment of nuclear breeders will create problems of safety and of proliferation. Nuclear energy's long-term success depends on resolving both of these problems. Collocation of nuclear facilities with a system of resident inspectors are measures that ought to help increase the proliferation-resistance as well as the safety of a large-scale, long-term nuclear system based on breeders. In such a long-term system a strengthened International Atomic Energy Agency (IAEA) is viewed as playing a central role.

Solar energy for heating and cooling (SHAC) doesn't work in every situation, but in some applications it can work very well. The right SHAC system, applied in the right place at the right time, has the potential to lower utility costs and customer electricity bills. Researchers are identifying preferred systems and their optimum applications. Because of their potential for load leveling, SHAC systems are of interest to the utility industry, even though these systems generally belong to individual homeowners. SHAC research programs involving the Electric Power Research Institute cover both active and passive systems. 3 references.

This simple technology can significantly decrease the amount of fuel used to cook food in rural areas of developing countries. The basis for the solar water pre-heater is the fact that the use of pre-heated water of 60C to cook food, particularly rice, dal and maize, lowers cooking times considerably and leads to substantial fuel savings.

Turning research into results, final report  

SciTech Connect

In September 1989, the ACEC Research and Management Foundation (ACEC/RMF) submitted a proposal to the US Department of Energy (DOE) in response to the Existing Buildings Efficiency Program`s Solicitation Number DE-PS01-89CE21034. On May 15, 1990, DOE informed ACEC/RMF that it had been selected for a grant award; the final agreement was signed on July 23, 1990. The purpose of the effort was to develop an information package showing engineering firms that energy services can be sold to owners and developers successfully and profitably, that not every design that goes beyond code results in a lawsuit, that owners can be shown the value of paying for the additional design analysis that energy efficiency design requires. The package was envisioned to include examples of buildings that succeed in terms of energy, cost, and design team benefits. It was further conceptualized as both a technical and marketing resource to provide helpful facts, references to relevant documents, graphic materials to be used during client presentations, and guidance on the latest in useful research results.

Use of bromodeoxyuridine immunocapture to identify psychrotolerant phenanthrene-degrading bacteria in phenanthrene-enriched polluted Baltic Sea sediments  

SciTech Connect

The aim of this study was to enrich and identify psychrotolerant phenanthrenedegrading bacteria from polluted Baltic Sea sediments. Polyaromatic hydrocarbon (PAH)-contaminated sediments were spiked with phenanthrene and incubated for 2 months in the presence of bromodeoxyuridine that is incorporated into the DNA of replicating cells. The bromodeoxyuridine-incorporated DNA was extracted by immunocapture and analyzed by terminal-restriction fragment length polymorphism and 16S rRNA gene cloning and sequencing to identify bacterial populations that were growing. In addition, degradation genes were quantified in the bromodeoxyuridine-incorporated DNA by real-time PCR. Phenanthrene concentrations decreased after 2 months of incubation in the phenanthrene-enriched sediments and this reduction correlated to increases in copy numbers of xylE and phnAc dioxygenase genes. Representatives of Exiguobacterium, Schewanella,Methylomonas, Pseudomonas, Bacteroides and an uncultured Deltaproteobacterium and a Gammaproteobacterium dominated the growing community in the phenanthrene spiked sediments. Isolates that were closely related to three of these bacteria (two pseudomonads and an Exiguobacterium sp.) could reduce phenanthrene concentrations in pure cultures and they all harbored phnAc dioxygenase genes. These results confirm that this combination of culture-based and molecular approaches was useful for identification of actively growing bacterial species with a high potential for phenanthrene degradation.

Fission neutron/gamma irradiation of Bacillus thuringiensis bacteria at the Texas A&M University Nuclear Science Center Reactor  

E-Print Network (OSTI)

The objective of this research is to fully characterize the effectiveness of the Texas A&M University Nuclear Science Center Reactor (TAMU NSCR) neutrons for bacterial sterilization, and to assess the secondary gamma flux produced when neutrons collide with nuclei in biological materials. Sterilization of bacteria by exposure to gamma rays and charged particles is fairly well understood. Exposure to neutrons and gamma rays from fission as a means of sterilization has not to date been adequately characterized. The lack of data on the relationship between biological detriment resulting from thermal or fast neutron exposures and absorbed doses as applied in countermeasures to weapons of mass destruction (WMD) is the primary motivation for this investigation of neutron doses to endospores. Bacillus thuringiensis (Bt) spores were irradiated after producing and sampling them using standard microbiological procedures. Irradiation was accomplished using neutrons and gamma rays from the 1-MW TRIGA reactor at the TAMU NSCR using a reactor power of 100 kilowatts (kW). The combination of neutron and gamma-ray absorbed dose provided an effective means of sterilization of these types of spores; it yielded a 100-percent kill for the first study. Survival curves have been developed, from subsequent experiments, for these energy dependent neutron interactions with biological materials using a combination of radiation dosimetry, microbiological culture techniques, and computer modeling (Monte Carlo Neutral Particle history modeling - MCNP). Survival curves indicate a D?? value of 321.08 Gy. Additional work is needed to investigate the specific bacteria used in biological weapons in order to understand agent-specific radiation sensitivity. Once this is done, more effective and meaningful experiments can be conducted in order to tailor the neutron source strength to the robustness of the threat.

ATCC 55702 has improved characteristics and qualities for the degradation of cellulosic materials.

Determination of coupled-lattice properties using turn-by-turn data  

SciTech Connect

A formalism for extracting coupled betatron parameters from multiturn, shock excited, beam position monitor data is described. The most important results are nonperturbative in that they do not rely on the underlying ideal lattice model. Except for damping, which is assumed to be exponential and small enough to be removed empirically, the description is symplectic. As well as simplifying the description, this leads to self-consistency checks that are applied to the data. The most important of these is a {open_quotes}magic ratio{close_quotes} of Fourier coefficients that is required to be a lattice invariant, the same at every beam position monitor. All formulas are applied to both real and simulated data. The real data was acquired June, 1992 at LEP as part of decoupling studies, using the LEP beam orbit measurement system. Simulated data, obtained by numerical tracking (TEAPOT) in the same (except for unknown errors) lattice, agrees well with real data when subjected to identical analysis. For both datasets, deviations between extracted and design parameters and deviations from self-consistency can be accounted for by noise and signal processing limitations. This investigation demonstrates that the LEP beam position system yields reliable local coupling measurements. It can be conservatively assumed that systems of similar design at the SSC and LHC will provide the measurements needed for local decoupling.

Competitive Reduction of Pertechnetate (99TcO4?) by Dissimilatory Metal Reducing Bacteria and Biogenic Fe(II)  

Science Conference Proceedings (OSTI)

The fate of pertechnetate (99Tc(VII)O4 -) during bioreduction was investigated in the presence of 2-line ferrihydrite (Fh) and various dissimilatory metal reducing bacteria (DMRB) (Geobacter, Anaeromyxobacter, Shewanella) in comparison with TcO4 - bioreduction in the absence of Fh. In the presence of Fh, Tc was present primarily as a fine-grained Tc(IV)/Fe precipitate that was distinct from the Tc(IV)O2 nH2O solids produced by direct biological Tc(VII) reduction. Aqueous Tc concentrations (reduced in the absence of Fh (4.0 10-8 to 1.0 10-7 mol L-1). EXAFS analyses of the bioreduced Fh-Tc products were consistent with variable chain length Tc-O octahedra bonded to Fe-O octahedra associated with the surface of the residual or secondary Fe(III) oxide. In contrast, biogenic TcO2 nH2O had significantly more Tc-Tc second neighbors and a distinct long-range order consistent with small particle polymers of TcO2. In Fe-rich subsurface sediments, the reduction of Tc(VII) by Fe(II) may predominate over direct microbial pathways, potentially leading to lower concentrations of aqueous 99Tc(IV).

Phase Preference by Active, Acetate-Utilizing Bacteria at the Rifle, CO Integrated Field Research Challenge Site  

SciTech Connect

Previous experiments at the Rifle, Colorado Integrated Field Research Challenge (IFRC) site demonstrated that field-scale addition of acetate to groundwater reduced the ambient soluble uranium concentration. In this report, sediment samples collected before and after acetate field addition were used to assess the active microbes via {sup 13}C acetate stable isotope probing on 3 phases [coarse sand, fines (8-approximately 150 {micro}m), groundwater (0.2-8 {micro}m)] over a 24-day time frame. TRFLP results generally indicated a stronger signal in {sup 13}C-DNA in the 'fines' fraction compared to the sand and groundwater. Before the field-scale acetate addition, a Geobacter-like group primarily synthesized {sup 13}C-DNA in the groundwater phase, an alpha Proteobacterium primarily grew on the fines/sands, and an Acinetobacter sp. and Decholoromonas-like OTU utilized much of the {sup 13}C acetate in both groundwater and particle-associated phases. At the termination of the field-scale acetate addition, the Geobacter-like species was active on the solid phases rather than the groundwater, while the other bacterial groups had very reduced newly synthesized DNA signal. These findings will help to delineate the acetate utilization patterns of bacteria in the field and can lead to improved methods for stimulating distinct microbial populations in situ.

Bacteria in Permafrost  

DOE Green Energy (OSTI)

Significant numbers of viable ancient microorganisms are known to be present within the permafrost. They have been isolated in both polar regions from the cores up to 400 m deep and ground temperatures of -27 C. The age of the cells corresponds to the longevity of the permanently frozen state of the soils, with the oldest cells dating back to {approx}3 million years in the Arctic, and {approx}5 million years in the Antarctic. They are the only life forms known to have retained viability over geological time. Thawing of the permafrost renews their physiological activity and exposes ancient life to modern ecosystems. Thus, the permafrost represents a stable and unique physicochemical complex, which maintains life incomparably longer than any other known habitats. If we take into account the depth of the permafrost layers, it is easy to conclude that they contain a total microbial biomass many times higher than that of the soil cover. This great mass of viable matter is peculiar to permafrost only.

Herd-level Risk Factors Associated with Antimicrobial Susceptibility Patterns and Distributions in Fecal Bacteria of Porcine Origin.  

E-Print Network (OSTI)

The purpose of this dissertation is threefold: to determine the differences in apparent prevalence and the antimicrobial susceptibility of Campylobacter spp. between antimicrobial-free and conventional swine farms; secondly, to introduce an appropriate statistical model to compare the minimum inhibitory concentration distributions of Escherichia coli and Campylobacter spp. isolated from both farm types; and thirdly, to examine the potential herd level risk factors that may be associated with antimicrobial resistance of Campylobacter spp. and E. coli isolates from finishers on antimicrobial-free and conventional farming systems. In addition, a critical review of studies that have compared the levels and patterns of antimicrobial resistance among animals from antimicrobial-free and conventional farming practices was performed. Fecal samples from 15 pigs were collected from each of 35 antimicrobial-free and 60 conventional farms in the Midwestern U.S. Campylobacter spp. was isolated from 464 of 1,422 fecal samples, and each isolate was tested for susceptibility to 6 antimicrobials. The apparent prevalence of Campylobacter spp. isolates was approximately 33 percent on both conventional and antimicrobial-free farms. The proportion of antimicrobial resistance among Campylobacter was higher for three antimicrobials within conventional compared to antimicrobial-free farms. The susceptibilities of populations of bacteria to antimicrobial drugs were summarized as minimum inhibitory concentration (MIC) frequency distributions. The use of MIC values removed the subjectivity associated with the choice of breakpoints which define an isolate as susceptible or resistant. A discrete-time survival analysis model was introduced as the recommended statistical model when MICs are the outcome. A questionnaire was completed by each farm manager on biosecurity, preventive medication, vaccines, disease history, and production management. Multivariable population-averaged statistical models were used to determine the relationships among antimicrobial susceptibility patterns and potential herd-level risk factors. Controlling for herd type (antimicrobial-free versus conventional), each antimicrobial-bacterial species combination yielded unique combinations of risk factors; however, housing type, history of rhinitis, farm ventilation, and history of swine flu were significant in more than one model. A variety of herd-level practices were associated with the prevalence of antimicrobial resistance on swine farms. Further studies are encouraged when considering interventions for antimicrobial resistance on both antimicrobial-free and conventional farms.

Complete genome sequences for the anaerobic, extremely thermophilic plant biomass-degrading bacteria Caldicellulosiruptor hydrothermalis, Caldicellulosiruptor kristjanssonii, Caldicellulosiruptor kronotskyensis, Caldicellulosiruptor owensenis, and Caldicellulosiruptor lactoaceticus  

Science Conference Proceedings (OSTI)

The genus Caldicellulosiruptor contains the most thermophilic, plant biomass-degrading bacteria isolated to date. Previously, genome sequences from three cellulolytic members of this genus were reported (C. saccharolyticus, C. bescii, and C. obsidiansis). To further explore the physiological and biochemical basis for polysaccharide degradation within this genus, five additional genomes were sequenced: C. hydrothermalis, C. kristjanssonii, C. kronotskyensis, C. lactoaceticus, and C. owensensis. Taken together, the seven completed and one draft-phase Caldicellulosiruptor genomes suggest that, while central metabolism is highly conserved, significant differences in glycoside hydrolase inventories and numbers of carbohydrate transporters exist, a finding which likely relates to variability observed in plant biomass degradation capacity.

Ambient Addition: How to turn urban noise into music  

E-Print Network (OSTI)

As human civilization devises ever more powerful machines, living among them may become more difficult. We may find ourselves surrounded by incidentally created sounds and noises which are out of synchronization with our momentary needs and discordant. Currently, legislating noise pollution is the only articulated solution and clearly it is not very effective. Our impression of sound, however, may be mediated and manipulated, transformed into something less jarring. So far, Walkmans and sound canceling headphones have done this, isolating us from noise but also from one another. In their place, a next generation headphone system is proposed which integrates environmental sound into a personal soundscape. It allows one to synthesize music from environmental sound using a number of digital signal processing (DSP) algorithms to create a sonic space in which the listener remains connected with his or her surroundings, is also cushioned from the most harsh and arrhythmic incursions and may also be drawn to

LCLS - The X-ray Laser Has Turned On  

SciTech Connect

On April 10, 2009 the Linac Coherent Light Source (LCLS), the world's first hard x-ray free electron laser, was brought to lasing. Producing an x-ray beam with over a billion times higher peak brightness that then most powerful existing syncrotron sources, it marked the beginning of a new era of science. The LCLS pulses arrive at a rate of 60 - 120 Hz in an energy range from 480 eV to 10 keV, with pulse lengths as short as a few fs to about 300 fs. Since October 2009, users have been performing experiments at the LCLS, and currently three of the six planned instruments are available. Although we stand only at the beginning of LCLS science, there is no doubt about the strong sense of early excitement.

New coal dewatering technology turns sludge to powder  

SciTech Connect

Virginian Tech's College of Engineering's Roe-Hoan Yoon and his group have developed a hyperbaric centrifuge that can dewater coal as fine as talcum powder. Such coal fines presently must be discarded by even the most advanced coal cleaning plants because of their high moisture content. The new technology can be used with the Microcel technology to remove ash, to re-mine the fine coal discarded to impoundments and to help minimize waste generation. Virginia Tech has received $1 million in funding from the US Department of State to also help the Indian coal industry produce a cleaner product. 1 photo.

Neutrino Physics at the Turn of the Millenium  

E-Print Network (OSTI)

Recent solar & atmospheric nu-data strongly indicate need for physics beyond the Standard Model. I review the ways of reconciling them in terms of 3-nu oscillations. Though not implied by data, bi-maximal nu-mixing models emerge as a possibility. SUSY with broken R-parity provides an attractive way to incorporate it, opening the possibility of testing nu-anomalies at high- energy colliders such as the LHC or at the upcoming long-baseline or nu- factory experiments. Reconciling, in addition, the LSND hint requires a fourth, light sterile neutrino, nus. The simplest are the most symmetric scenarios, in which 2 of the 4 neutrinos are maximally-mixed and lie at the LSND scale, while the others are at the solar scale. The lightness of nus, the nearly maximal atmospheric mixing, and the solar/atmospheric splittings all follow naturally from the assumed lepton-number symmetry and its breaking. These basic schemes can be distinguished at neutral-current-sensitive solar & atmospheric neutrino experiments such as SNO. However underground experiments have not yet proven neutrino masses, as there are many alternatives. For example flavour changing interactions can play an important role in the explanation of solar and contained atmospheric data and could be tested e.g through \\mu \\to e + \\gamma, \\mu-e conversion in nuclei, unaccompanied by neutrino-less double beta decay. Conversely, a short-lived numu might play a role in the explanation of the atmospheric data. Finally, in the presence of a nus, a long-lived heavy nutau could delay the time at which the matter and radiation contributions to the energy density of the Universe become equal, reducing density fluctuations on smaller scales, thus saving the standard CDM scenario, while the light nue, numu and nus would explain the solar & atmospheric data.

Turning big bang into big bounce. I. Classical dynamics  

SciTech Connect

The big bounce (BB) transition within a flat Friedmann-Robertson-Walker model is analyzed in the setting of loop geometry underlying the loop cosmology. We solve the constraint of the theory at the classical level to identify physical phase space and find the Lie algebra of the Dirac observables. We express energy density of matter and geometrical functions in terms of the observables. It is the modification of classical theory by the loop geometry that is responsible for BB. The classical energy scale specific to BB depends on a parameter that should be fixed either by cosmological data or determined theoretically at quantum level, otherwise the energy scale stays unknown.

Isentropic compression studies using the NHMFL single turn  

SciTech Connect

Magnetic isentropic compression experiments (ICE) provide the most accurate shock free compression data for materials at megabar stresses. Recent ICE experiments performed on the Sandia Z-machine (Asay, 1999) and at the Los Alamos High Explosive Pulsed Power facility (Tasker, 2006) are providing our nation with data on material properties in extreme dynamic high stress environments. The LANL National High Magnetic Field Laboratory (NHMFL) can offer a less complex ICE experiment at high stresses (up to {approx}1Mbar) with a high sample throughput and relatively low cost. This is not to say that the NHMFL technique will replace the other methods but rather complement them. For example, NHMFL-ICE is ideal for the development of advanced diagnostics, e.g., to detect phase changes. We will discuss the physics of the NHMFL-ICE experiments and present data from the first proof-of-principle experiments that were performed in September 2010.

Turning off the lights: How dark is dark matter?  

SciTech Connect

We consider current observational constraints on the electromagnetic charge of dark matter. The velocity dependence of the scattering cross section through the photon gives rise to qualitatively different constraints than standard dark matter scattering through massive force carriers. In particular, recombination epoch observations of dark matter density perturbations require that {epsilon}, the ratio of the dark matter to electronic charge, is less than 10{sup -6} for m{sub X}=1 GeV, rising to {epsilon}<10{sup -4} for m{sub X}=10 TeV. Though naively one would expect that dark matter carrying a charge well below this constraint could still give rise to large scattering in current direct detection experiments, we show that charged dark matter particles that could be detected with upcoming experiments are expected to be evacuated from the Galactic disk by the Galactic magnetic fields and supernova shock waves and hence will not give rise to a signal. Thus dark matter with a small charge is likely not a source of a signal in current or upcoming dark matter direct detection experiments.

Test of electron beam technology on Savannah River Laboratory low-activity aqueous waste for destruction of benzene, benzene derivatives, and bacteria  

Science Conference Proceedings (OSTI)

High energy radiation was studied as a means for destroying hazardous organic chemical wastes. Tests were conducted at bench scale with a {sup 60}Co source, and at full scale (387 l/min) with a 1.5 MV electron beam source. Bench scale tests for both benzene and phenol included 32 permutations of water quality factors. For some water qualities, as much as 99.99% of benzene or 90% of phenol were removed by 775 krads of {sup 60}Co irradiation. Full scale testing for destruction of benzene in a simulated waste-water mix showed loss of 97% of benzene following an 800 krad dose and 88% following a 500 krad dose. At these loss rates, approximately 5 Mrad of electron beam irradiation is required to reduce concentrations from 100 g/l to drinking water quality (5 {mu}g/l). Since many waste streams are also inhabited by bacterial populations which may affect filtering operations, the effect of irradiation on those populations was also studied. {sup 60}Co and electron beam irradiation were both lethal to the bacteria studied at irradiation levels far lower than were necessary to remove organic contaminants.

Bacterial and Archaea Community Present in the Pine Barrens Forest of Long Island, NY: Unusually High Percentage of Ammonia Oxidizing Bacteria  

Science Conference Proceedings (OSTI)

Of the few preserved areas in the northeast of United States, the soil in the Pine Barrens Forests presents a harsh environment for the microorganisms to grow and survive. In the current study we report the use of clustering methods to scientifically select the sampling locations that would represent the entire forest and also report the microbial diversity present in various horizons of the soil. Sixty six sampling locations were selected across the forest and soils were collected from three horizons (sampling depths). The three horizons were 0-10 cm (Horizon O); 11-25 cm (Horizon A) and 26-40 cm (Horizon B). Based on the total microbial substrate utilization pattern and K-means clustering analysis, the soil in the Pine Barrens Forest can be classified into four distinct clusters at each of the three horizons. One soil sample from each of the four clusters were selected and archaeal and bacterial populations within the soil studied using pyrosequencing method. The results show the microbial communities present in each of these clusters are different. Within the microbial communities present, microorganisms involved in nitrogen cycle occupy a major fraction of microbial community in the soil. High level of diversity was observed for nitrogen fixing bacteria. In contrast, Nitrosovibrio and Nitrosocaldus spp are the single bacterial and archaeal population respectively carrying out ammonia oxidation in the soil.

High voltage, fast turn-on and turn-off switch: Final report for period September 2, 1998 - March 17, 1999  

DOE Green Energy (OSTI)

The aspect to be investigated during this contract was an electron-beam triggered diamond switch to be used in high power modulators. Today's high power modulators require higher voltage switches than those developed to date. Specifically, the proposed 1 TeV linear collider, the NLC/ILC at the Stanford Linear Accelerator Center (SLAC), consists of two linacs with 6600 X-Band klystrons powered by 3300 high power modulators. These modulators require switches capable of handling 80 kV, switching 8 kA with pulse durations ranging from 2 ps (linac) to 6 {micro}s (pre-linac) with switching times <50 ns at pulse repetition frequencies up to 180 Hz. In addition the large number of switches and other components dictate a pulse to pulse jitter of <10 ns and a mean time between failures of at least 50,000 hours. The present approach is to use hydrogen filled thyratrons. While these switches meet the voltage and conduction current requirements they lack the required reliability (pulse to pulse jitter) and lifetime. Research to improve these aspects is in progress. A solid state switch inherently offers the required reliability and lifetime. However, Si-based switches developed to date are limited to about 5 kV and several must be stacked in series to deliver the required voltage. This further increases the already large parts count and compromises reliability and lifetime. A monolithic, solid state switch capable of meeting all the requirements for X-Band modulators would be ideal. DOE selected this proposal for a Phase 1 SBIR award and this final report describes the progress made during the contract.

Cloning systems for Rhodococcus and related bacteria  

DOE Patents (OSTI)

A plasmid transformation system for Rhodococcus was developed using an Escherichia coli-Rhodococcus shuttle plasmid. Rhodococcus sp. H13-A contains three cryptic indigenous plasmids, designated pMVS100, pMVS200 and pMVS300, of 75, 19.5 and 13.4 kilobases (Kb), respectively. A 3.8 Kb restriction fragment of pMVS300 was cloned into pIJ30, a 6.3 Kb pBR322 derivative, containing the E. coli origin of replication (ori) and ampicillin resistance determinant (bla) as well as a Streptomyces gene for thiostrepton resistance, tsr. The resulting 10.1 Kb recombinant plasmid, designated pMVS301, was isolated from E. coli DH1 (pMVS301) and transformed into Rhodococcus sp. AS-50, a derivative of strain H13-A, by polyethylene glycol-assisted transformation of Rhodococcus protoplasts and selection for thiostrepton-resistant transformants. This strain was deposited with the ATCC on Feb. 1, 1988 and assigned ATCC 53719. The plasmid contains the Rhodococcus origin of replication. The plasmid and derivatives thereof can therefore be used to introduce nucleic acid sequences to and from Rhodococcus for subsequent expression and translation into protein. The isolated origin of replication can also be used in the construction of new vectors.

Optimized procedures for extractioin, purification and characterization of exopolymeric substances (eps) from two bacteria (sagittula stellata and pseudomonas fluorescens biovar ii) with relevance to the study of actinide binding in aquatic environments  

E-Print Network (OSTI)

The extracellular polymeric substances (EPS) of marine bacterium Sagittula stellata and soil bacterium Pseudomonas fluorescens Biovar II, were extracted by six methods referred to the bibliography, efficacies of which were compared based on the EPS yield, composition as well as cell disturbance. Purification methods on these EPS were also improved, which proved to be more cost-effective and involve less interference from broth, compared to previous methods. Size exclusion chromatography (SEC) proved to be a useful tool, providing the fingerprints of the EPS extracted by different methods or after each purification step. Studies of the EPS production and composition at different growth stages provided abundant information and a basis for further in-depth studies. Results from SEC demonstrated that bacterial EPS had a constant molecular weight distribution all through the life but with various polymers in different proportions. Three fractions were successfully isolated by a combination of SEC and anion exchange chromatography for non-attched EPS produced by Pseudomonas flurorescens Biovar II. Protein turned out to be a major component of EPS in their native states, which was mixed with the broth material and couldnt be recognized previously. The EPS harvested at the optimal time of the bacterial life was purified according to the improved method and was more enriched in polysaccharides, with small amounts of proteins, giving the molecules amphiphilic properties. In addition, simultaneous determination of neutral sugars and uronic acids by GC-EI-MS provided more information on the monosaccharide composition of the exopolysaccharides. Isoelectric focusing (IEF) spectra of the bacterial EPS spiked with Pu/Th, and Pu-enriched Rocky Flats Environmental Technology Site (RFETS) soil organic colloid spiked with Th showed similar activity distributions of both actinides along the pH gradient, with the activities of both actinides focusing on the low pH region. Characterizations of this Pu-enriched IEF extract from RFETS soil by spectrophotometric methods and ATR-FTIR indicated the co-presence of lipids, proteins and polysaccharides, in contrast to the bacterial EPS, which showed a simpler composition. This suggests that Th/Pu binding to organic macromolecules is more determined by the availability of binding functional groups rather than the exact specific compounds.

Quantification of the Antimicrobial Substances Produced by Lactic Acid Bacteria used as an Intervention to Inhibit Escherichia coli O157:H7 and Salmonella in vitro and on Fresh Spinach (Spinacia oleracea)  

E-Print Network (OSTI)

The metabolic activity of bacterial microorganisms may influence the growth and metabolic activities of other microbes that are present in any specific niche. Lactic acid bacteria (LAB) are antagonistic to some microbial pathogens by the metabolic production of compounds with antimicrobial activity. Consequently, investigators have measured the effects of those antimicrobials to inhibit specific pathogens. However, the mode(s) of action of LAB against foodborne pathogens on products and/or in broth is not completely understood. Therefore, the objectives of this research were to (i) determine the LAB dose required for inhibition of Escherichia coli O157:H7 and Salmonella enterica in vitro and on spinach, and (ii) identify and quantify the major antimicrobial substances synthesized by LAB as a function of postinoculation storage conditions. Assays were performed at 7 degrees C under aerobic conditions. The foodborne pathogens dose responses were assessed in a liquid microbiological medium (in vitro) and on spinach leaf surfaces. Different levels of foodborne pathogens and LAB cultures were used. The addition of LAB cultures did not reduce E. coli O157:H7 or Salmonella enterica populations when performed in vitro. However, when LAB cultures were sprayed on the surfaces of spinach leaves at 8.0 log10 CFU/g, there were significant reductions on E. coli O157:H7 of 1.62 and 0.73 log10 CFU/g (after 3 days) and on Salmonella enterica of 1.85 and 0.71 log10 CFU/g (after 6 days) for treatments inoculated with an initial level of 2.0 and 4.0 log10 CFU/g, respectively. After quantification of the antimicrobial compounds synthesized by LAB cultures, they were correlated against the population growth of targeted pathogens. The highest Llactic acid (3.71 plus/minus 0.14 micromoles/ml, day 12) and hydrogen peroxide (3.72 plus/minus 3.34 microM, day 6) production were obtained from the in vitro sample inoculated with 8.0 log10 CFU/ml of LAB and 0.0 log10 CFU/ml of pathogens. The highest bacteriocin production (0.1 plus/minus 0.01 mg/ml) was obtained from the in vitro sample with 8.0 log10 CFU/ml of LAB and 2.0 log10 CFU/ml of pathogens. In conclusion, the LAB cultures were able to produce detectable amounts of antimicrobials that may be used as intervention and/or sciencebased practice against foodborne pathogens by producers and the industry.

Vortex nozzle for segmenting and transporting metal chips from turning operations  

DOE Patents (OSTI)

Apparatus for collecting, segmenting and conveying metal chips from machining operations utilizes a compressed gas driven vortex nozzle for receiving the chip and twisting it to cause the chip to segment through the application of torsional forces to the chip. The vortex nozzle is open ended and generally tubular in shape with a converging inlet end, a constant diameter throat section and a diverging exhaust end. Compressed gas is discharged through angled vortex ports in the nozzle throat section to create vortex flow in the nozzle and through an annular inlet at the entrance to the converging inlet end to create suction at the nozzle inlet and cause ambient air to enter the nozzle. The vortex flow in the nozzle causes the metal chip to segment and the segments thus formed to pass out of the discharge end of the nozzle where they are collected, cleaned and compacted as needed.

SEI uruguay project: Technical specifications. Turn-key' contract for La Tablada repowering. Export trade information  

Science Conference Proceedings (OSTI)

The study, conducted by Southern Electric International (SEI), was funded by the U.S. Trade and Development Agency on behalf of U.T.E., the Government of Uruguay's electric power company. It is an assessment of three potential projects under consideration by U.T.E. The changes resulting from these projects would add 120 to 360 megawatts capacity to the current system. The first option would involve repowering Jose Batlle y Ordonez Units 3 and 4. As an alternate to this plan, U.T.E. is considering a new combined cycle plant at a Greenfield site. The third project would increase capacity at La Tablada.

Vortex nozzle for segmenting and transporting metal chips from turning operations  

DOE Patents (OSTI)

This invention is comprised of an apparatus for collecting, segmenting and conveying metal chips from machining operations which utilizes a compressed gas driven vortex nozzle for receiving the chip and twisting it to cause the chip to segment through the application of torsional forces to the chip. The vortex nozzle is open ended and generally tubular in shape with a converging inlet end, a constant diameter throat section and a diverging exhaust end. Compressed gas is discharged through angled vortex ports in the nozzle throat section to create vortex flow in the nozzle and through an annular inlet at the entrance to the converging inlet end to create suction at the nozzle inlet and cause ambient air to enter the nozzle. The vortex flow in the nozzle causes the metal chip to segment and the segments thus formed to pass out of the discharge end of the nozzle where they are collected, cleaned and compacted as needed.

REDUCTIONS WITHOUT REGRET: DETAILS - AVOIDING BOX CANYONS, ROACH MOTELS, AND WRONG TURNS  

SciTech Connect

The United States is concurrently pursuing the goals of reducing the size of its nuclear weapons force strategic and non-strategic, deployed and non-deployed and of modernizing the weapons it continues to possess. Many of the existing systems were deployed 30 to 50 years ago, and the modernization process can be expected to extend over the next decade or more. Given the impossibility of predicting the future over the lifetime of systems that could extend to the end of this century, it is essential that dead ends in force development be avoided, and the flexibility and availability of options be retained that allow for Scalability downward in the event that further reductions are agreed upon; Reposturing to respond to changes in threat levels and to new nuclear actors; and Breakout response in the event that a competitor significantly increases its force size or force capability, In this paper, we examine the current motivations for reductions and modernization; review a number of historical systems and the attendant capabilities that have been eliminated in recent decades; discuss the current path forward for the U.S. nuclear force; provide a view of the evolving deterrence situation and our assessment of the uncertainties involved; and present examples of possibly problematic directions in force development. We close with our thoughts on how to maintain flexibility and the availability of options for which a need might recur in the future.

Study of Energy and Demand Savings on a High Efficiency Hydraulic Pump System with Infinite Turn Down Technology (ITDT)  

E-Print Network (OSTI)

Detailed field measurement and verification of electrical energy (kWh) and demand (kW) savings is conducted on an injection molding machine used in typical plastic manufacturing facility retrofitted with a high efficiency hydraulic pump system. Significant energy usage and demand savings are verified for the retrofitted injection molding machine. The savings are realized by electronically attenuating the torque of a positive displacement pump irrespective of the volumetric flow required by the cycle. With help of a power analyzer, power quality issues are addressed. Some voltage distortion was observed due to the harmonic currents introduced by the control algorithm of the high efficiency hydraulic system. A comparative study of electrical energy and demand savings between an injection molding machine retrofitted with the high efficiency hydraulic pump system or variable frequency drive will also be presented.

How to Turn Property Tax Exemptions into Revenue for Local Governments Institute for Wisconsins Future  

E-Print Network (OSTI)

Wisconsin citizens want strong communities, reasonable state and local taxes and a revenue system in which all individuals, businesses and organizations pay a fair share. IWFs Fair and Adequate series of reports examines how the current tax system works and what changes are needed to create a fair system that adequately funds the services needed for the common good. Wisconsin Property Tax Executive Summary Property tax revenue is the fuel for community operations. It generates $9.4 billion a year to pay a major portion of the cost to run schools, public safety systems, all forms of transportation, technical colleges and the infrastructure that supports us. The property tax is Wisconsins oldest and largest mechanism for citizens and businesses to share the expense of basic and vital public structures. The property tax is also the tax some people love to hate the most. There are serious criticisms of the property tax structure in Wisconsin: Property taxes in this state are higher than in most other states; Middle-class families pay a higher percent of their income on property taxes for their homes than wealthy households; Property tax rates are not consistent, but vary widely from one community to another;
