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 acids—a 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 acids—overriding its natural tendency to use solar energy solely for cell growth and maximizing the solar-to-fuel conversion process. ASU’s 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.

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?

Counting Bacteria

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.

Tune Evaluation From Phased BPM Turn-By-Turn Data  

E-Print Network (OSTI)

In fast ramping synchrotrons like the Fermilab Booster the conventional methods of betatron tune evaluation from the turn-by-turn data may not work due to rapid changes of the tunes (sometimes in a course of a few dozens of turns) and a high level of noise. We propose a technique based on phasing of signals from a large number of BPMs which significantly increases the signal to noise ratio. Implementation of the method in the Fermilab Booster control system is described and some measurement results are presented.

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.

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

Hamilton's theory of turns revisited  

E-Print Network (OSTI)

We present a new approach to Hamilton's theory of turns for the groups SO(3) and SU(2) which renders their properties, in particular their composition law, nearly trivial and immediately evident upon inspection. We show that the entire construction can be based on binary rotations rather than mirror reflections.

Diamond turning machine controller implementation  

SciTech Connect

The standard controller for a Pnuemo ASG 2500 Diamond Turning Machine, an Allen Bradley 8200, has been replaced with a custom high-performance design. This controller consists of four major components. Axis position feedback information is provided by a Zygo Axiom 2/20 laser interferometer with 0.1 micro-inch resolution. Hardware interface logic couples the computers digital and analog I/O channels to the diamond turning machine`s analog motor controllers, the laser interferometer, and other machine status and control information. It also provides front panel switches for operator override of the computer controller and implement the emergency stop sequence. The remaining two components, the control computer hardware and software, are discussed in detail below.

Diamond turning of thermoplastic polymers  

SciTech Connect

Single point diamond turning studies were made using a series of thermoplastic polymers with different glass transition temperatures. Variations in surface morphology and surface roughness were observed as a function of cutting speed. Lower glass transition temperatures facilitate smoother surface cuts and better surface finish. This can be attributed to the frictional heating that occurs during machining. Because of the very low glass transition temperatures in polymeric compared to inorganic glasses, the precision machining response can be very speed sensitive.

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

Study examines sulfate-reducing bacteria activity  

SciTech Connect

Low-sulfate seawater injection can reduce the potential of an oil reservoir turning sour because of sulfate-reducing bacteria. Sulfate-reducing bacteria (SRB) convert sulfate ions in seawater used in waterflooding into sulfide with the concomitant oxidation of a carbon source. A recent study at Capcis investigated the efficiency of SRB under various conditions of sulfate limitation. This study was conducted in a flowing bioreactor at 2,000 psia with different temperature zones (mesophilic 35 C and thermophilic 60--80 C). The study mixed microfloral populations derived from real North Sea-produced fluids, and included an active population of marine methanogenic bacteria present to provide competition for the available carbon sources. In general, results showed that SRB continue to convert sulfate to sulfide in stoichiometric quantities without regard to absolute concentrations. The paper discusses the results and recommends nanofiltration of seawater for ``sweet`` reservoirs.

Ampicillin and Bacteria  

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

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.

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

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.

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).

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.

Measurement of tool forces in diamond turning  

SciTech Connect

A dynamometer has been designed and built to measure forces in diamond turning. The design includes a 3-component, piezoelectric transducer. Initial experiments with this dynamometer system included verification of its predicted dynamic characteristics as well as a detailed study of cutting parameters. Many cutting experiments have been conducted on OFHC Copper and 6061-T6 Aluminum. Tests have involved investigation of velocity effects, and the effects of depth and feedrate on tool forces. Velocity has been determined to have negligible effects between 4 and 21 m/s. Forces generally increase with increasing depth of cut. Increasing feedrate does not necessarily lead to higher forces. Results suggest that a simple model may not be sufficient to describe the forces produced in the diamond turning process.

An apparatus for measuring turn-by-turn transverse beam profile in electron storage rings  

SciTech Connect

A new apparatus is designed to measure the beam profile turn-by-turn using synchrotron light. The apparatus consists of optical fibers, photo multiplier tubes and digitizers. It is cost efficient and easy to operate. Monte Carlo simulations have shown that the apparatus has an acceptable resolution. The concept has been tested preliminarily at the SLC damping ring, and a full equipment is being set up at CESR to observe coherent beam-beam phenomenon.

Genomics of cellulolytic bacteria  

Science Journals Connector (OSTI)

The heterogeneous plant biomass is efficiently decomposed by the interplay of a great number of different enzymes. The enzyme systems in cellulolytic bacteria have been investigated by sequencing and bioinformatic analysis of genomes from plant biomass degrading microorganisms with valuable insights into the variety of the involved enzymes. This broadened our understanding of the biochemical mechanisms of plant polymer degradation and made the enzymes applicable for modern biotechnology. A list of the truly cellulolytic bacteria described and the available genomic information was examined for proteins with cellulolytic and hemicellulolytic capability. The importance of the isolation, characterization and genomic sequencing of cellulolytic microorganisms and their usage for sustainable energy production from biomass and other residues, is emphasized.

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.

Hamilton's Turns for the Lorentz Group  

E-Print Network (OSTI)

Hamilton in the course of his studies on quaternions came up with an elegant geometric picture for the group SU(2). In this picture the group elements are represented by ``turns'', which are equivalence classes of directed great circle arcs on the unit sphere $S^2$, in such a manner that the rule for composition of group elements takes the form of the familiar parallelogram law for the Euclidean translation group. It is only recently that this construction has been generalized to the simplest noncompact group $SU(1,1) = Sp(2, R) = SL(2,R)$, the double cover of SO(2,1). The present work develops a theory of turns for $SL(2,C)$, the double and universal cover of SO(3,1) and $SO(3,C)$, rendering a geometric representation in the spirit of Hamilton available for all low dimensional semisimple Lie groups of interest in physics. The geometric construction is illustrated through application to polar decomposition, and to the composition of Lorentz boosts and the resulting Wigner or Thomas rotation.

Bacteria eats radioactive waste  

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

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!

Electrodeposited coatings for diamond turning applications  

SciTech Connect

Electrodeposited coatings are attractive for precision machining operations because thick coatings can be economically applied, with good adhesion, to a variety of substrates. Approximately 20 pure metals and a large number of alloys can be deposited from aqueous solutions. Fused salt and organic solvent electrolytes can be used to lengthen the list of metals that can be electrodeposited. However, both the choice of the metallic coating and the control of the plating process are critical for success in precision finishing of electrodeposited coatings. Some preliminary results at the National Institute of Standards and Technology and at the Lawrence Livermore National Laboratory suggest that electrodeposited nickel-phosphorus alloys are excellent coatings for single point diamond turning from the standpoint of material properties and low tool wear. Electrodeposited aluminum and aluminum alloy coatings also merit consideration for precision finishing where weight is an important factor. 10 refs., 6 figs.

Application of the lie-transform perturbation theory for the turn-by-turn data analysis  

SciTech Connect

Harmonic analysis of turn-by-turn BPM data is a rich source of information on linear and nonlinear optics in circular machines. In the present report the normal form approach first introduced by R. Bartolini and F. Schmidt is extended on the basis of the Lie-transform perturbation theory to provide direct relation between the sources of perturbation and observable spectra of betatron oscillations. The goal is to localize strong perturbing elements, find the resonance driving terms--both absolute value and phase--that are necessary for calculation of the required adjustments in correction magnet circuits: e.g. skew-quadrupoles for linear coupling correction. The theory is nonlinear and permits to analyze higher order effects, such as coupling contribution to beta-beating and nonlinear sum resonances.

LINEAR COUPLING CORRECTION WITH N-TURN MAPS.  

SciTech Connect

The linear one-turn map of a storage ring contains coupling information on which a correction algorithm can be based. In principal, the one-turn matrix can be fitted from turn-by-turn data of beam position monitors after a kick was applied. However, the so obtained coupling information often sinks into the noise floor. The signal-to-noise ratio of the coupling information can be greatly enhanced by fitting maps for larger turn numbers N, equal to half the beat period. With the so obtained N-turn map an automated global coupling correction is possible without the need for a tune change. This is demonstrated for the Relativistic Heavy Ion Collider where the algorithm is implemented for operational use at injection.

LX-17 Corner-Turning and Reactive Flow Failure  

SciTech Connect

We have performed a series of highly-instrumented experiments examining corner-turning of detonation. A TATB booster is inset 15 mm into LX-17 (92.5% TATB, 7.5% kel-F) so that the detonation must turn a right angle around an air well. An optical pin located at the edge of the TATB gives the start time of the corner-turn. The breakout time on the side and back edges is measured with streak cameras. Three high-resolution X-ray images were taken on each experiment to examine the details of the detonation. We have concluded that the detonation cannot turn the corner and subsequently fails, but the shock wave continues to propagate in the unreacted explosive, leaving behind a dead zone. The detonation front farther out from the corner slowly turns and eventually reaches the air well edge 180{sup o} from its original direction. The dead zone is stable and persists 7.7 {micro}s after the corner-turn, although it has drifted into the original air well area. Our regular reactive flow computer models sometimes show temporary failure but they recover quickly and are unable to model the dead zones. We present a failure model that cuts off the reaction rate below certain detonation velocities and reproduces the qualitative features of the corner-turning failure.

Observation of diamond turned OFHC copper using Scanning Tunneling Microscopy  

SciTech Connect

Diamond turned OFHC copper samples have been observed within the past few months using the Scanning Tunneling Microscope. Initial results have shown evidence of artifacts which may be used to better understand the diamond turning process. The STM`s high resolution capability and three dimensional data representation allows observation and study of surface features unobtainable with conventional profilometry systems. Also, the STM offers a better quantitative means by which to analyze surface structures than the SEM. This paper discusses findings on several diamond turned OFHC copper samples having different cutting conditions. Each sample has been cross referenced using STM and SEM.

Idling! And yet, every year, Americans waste 3 billion gallons of fuel by idling their vehicles. Idling is running a vehicle any time that it's not moving. In this condition, the car's fuel economy is exactly zero miles per gallon. Although many people think that restarting the engine too often will wear out the starter, that idea is just an "old husband's tale." In fact, idling places unnecessary wear-and-tear on the engine, and many manufacturers discourage it. Although drivers can't avoid some amount of idling, such as being stuck in

NEWTON: Bacteria Survival in the Stomach  

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

Bacteria Survival in the Stomach Bacteria Survival in the Stomach Name: Lianne Status: other Grade: other Location: Outside U.S. Country: USA Date: Summer 2013 Question: Is H. 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.

Time to recognise that mitochondria are bacteria?  

Science Journals Connector (OSTI)

The scientific community is comfortable with recognising mitochondria as organelles that happen to be descendants of bacteria. Here, I playfully explore the arguments for and against a phylogenetic fundamentalism that states that mitochondria are bacteria and should be given their own taxonomic family, the Mitochondriaceae. I also explore the consequences of recognizing mitochondria as bacteria for our understanding of the systemic response to trauma and for the prospects of creating transgenic mitochondria.

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

SciTech Connect

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.

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.

Self-excited vibrations in turning: cutting moment analysis  

E-Print Network (OSTI)

This work aims at analysing the moment effects at the tool tip point and at the central axis, in the framework of a turning process. A testing device in turning, including a six-component dynamometer, is used to measure the complete torsor of the cutting actions in the case of self-excited vibrations. Many results are obtained regarding the mechanical actions torsor. A confrontation of the moment components at the tool tip and at the central axis is carried out. It clearly appears that analysing moments at the central axis avoids the disturbances induced by the transport of the moment of the mechanical actions resultant at the tool tip point. For instance, the order relation between the components of the forces is single. Furthermore, the order relation between the moments components expressed at the tool tip point is also single and the same one. But at the central axis, two different order relations regarding moments are conceivable. A modification in the rolling moment localization in the (y, z) tool plan is associated to these two order relations. Thus, the moments components at the central axis are particularly sensitive at the disturbances of machining, here the self-excited vibrations.

The Kicker Systems for the PS Multi-turn Extraction  

E-Print Network (OSTI)

A five-turn continuous extraction has up to now been used to transfer the proton beam from the CERN PS to the SPS. This extraction uses an electrostatic septum to cut the filament beam into five slices, causing losses of about 15 %. These losses would be an even greater drawback when the beam intensity is increased for the CERN Neutrinos to Gran Sasso (CNGS) facility. To overcome this Multi-Turn Extraction (MTE) has been implemented, in which the beam is separated, prior to extraction, into a central beam core and four islands. Each beamlet is extracted using a set of kickers and a magnetic septum. For the kickers two new pulse generators have been built, each containing a lumped element Pulse Forming Network (PFN) of 12.5 W, 80 kV and 10.5 ms. For cost reasons existing 15 W transmission line kicker magnets are reused. The PFN characteristic impedance deliberately mismatches that of the magnets to allow a higher maximum kick. The PFN design has been optimised such that undesirable side-effects of the impedanc...

Turning the tide of public opinion on nuclear power  

SciTech Connect

Until the early 1970s, the tide of public opinion in the United States was strongly in favor of nuclear power. New power plants were coming on line frequently, and in 1973-74, there were close to 40 new orders per year for new reactors in the United States. Official government projections estimated 1000 operating reactors by the year 2000. Fuel reprocessing, plutonium recycle, and breeder reactor development were also proceeding smoothly and rapidly. But, in the mid-1970s, the tide suddenly turned against the nuclear industry. How did this come about? In the late 1960s, energetic and idealistic young people who had never experienced economic insecurity or World Wars came of age. Environmentalism was an attractive outlet for their activity in most of the Western world. In the United States, opposition to the Vietnam War, in which these young people had a personal stake, was even more popular at first, but by the early 1970s, Vietnam was winding down, and they turned also to Environmentalism. Numerous environmental groups started up, aided heavily by the favorable connotation of the very word {open_quotes}environmentalist{close_quotes} in the public mind. Their organizational experience, political savvy, and media connections gained from their antiwar protests were powerful assets. But the groups needed specific targets to attack, and they soon found that nuclear power was well-suited for that purpose. Here was a new technology, coming on at a very rapid pace. To the public, radiation was highly mysterious, and people were well aware that it could be dangerous. And, the word danger had taken on a new meaning. Previous generations were well acquainted with death and were much less averse to risk-taking than the generation of the 1970s.

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

November 16, 2009 - 7:42pm Addthis Elizabeth Spencer Communicator, National Renewable Energy Laboratory I can be a strange and particular person at times. So here is a post wherein I will be strangely particular about setting the temperature on your thermostat. You often hear about how you should turn down the thermostat to save energy, and there are a slew of helpful ideas on the subject. I'm sure you've heard some of them right here on this blog: You can turn the thermostat down when you're out, when you're sleeping, and you can save about 1% on your energy bill per degree you turn your thermostat down! This is all very exciting. But before you go crazy with turning down the thermostat really low, I'd

Method And Apparatus For Reducing Sample Dispersion In Turns And Junctions Of Micro-Channel Systems  

DOE Patents (OSTI)

What is disclosed pertains to improvement in the performance of microchannel devices by providing turns, wyes, tees, and other junctions that produce little dispersion 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. The low dispersion features are particularly suited for microfluidic devices and systems using either electromotive force, pressure, or combinations thereof as the principle of fluid transport. Such microfluidic devices and systems are useful for separation of components, sample transport, reaction, mixing, dilution or synthesis, or combinations thereof.

Novel passive lossless turn-on snubber for voltage source inverters  

SciTech Connect

A novel passive lossless turn-on snubber with a soft clamped turn-off snubber circuit for voltage source inverters is proposed. The energy trapped in the snubber is recovered into the dc supply and load without any active devices, associated control circuitry, or resistors. The overshoot voltage on the switches is clamped, and the peak switch current is low, making this snubber suitable for use in high-power insulated gate bipolar transistor (IGBT) inverters.

The study of how photosynthetic organisms convert light offers insight not only into nature's evolutionary process, but may also give clues as to how best to design and manipulate artificial photosynthetic systems -- and also how far we can drive natural photosynthetic systems beyond normal operating conditions, so that they can harvest energy for us under otherwise extreme conditions. In addition to its interest from a basic scientific perspective, therefore, the goal to develop a deep quantitative understanding of photosynthesis offers the potential payoff of enhancing our current arsenal of alternative energy sources for the future. In the following Chapter, we consider the trade-off between dynamics, structure and function of light harvesting membranes in Rps.

Use of thermophilic bacteria for bioremediation of petroleum contaminants  

SciTech Connect

Several strains of thermophilic bacteria were isolated from the environment of the United Arab Emirates. These bacteria show extraordinary resistance to heat and have their maximum growth rate around 60--80 C. This article investigates the potential of using these facultative bacteria for both in situ and ex situ bioremediation of petroleum contaminants. In a series of batch experiments, bacterial growth was observed using a computer image analyzer following a recently developed technique. These experiments showed clearly that the growth rate is enhanced in the presence of crude oil. This is coupled with a rapid degradation of the crude oil. These bacteria were found to be ideal for breaking down long-chain organic molecules at a temperature of 40 C, which is the typical ambient temperature of the Persian Gulf region. The same strains of bacteria are also capable of surviving in the presence of the saline environment that can prevail in both sea water and reservoir connate water. This observation prompted further investigation into the applicability of the bacteria in microbial enhanced oil recovery. In the United Arab Emirates, the reservoirs are typically at a temperature of around 85 C. Finally, the performance of the bacteria is tested in a newly developed bioreactor that uses continuous aeration through a transverse slotted pipe. This reactor also uses mixing without damaging the filamentous bacteria. In this process, the mechanisms of bioremediation are identified.

However, a new study conducted by environmental scientists at the U.S. Department of Energy's Argonne National Laboratory has demonstrated a way to enlist bacteria in the fight to cleanse some of the country's most intractably polluted locations. Last year, a team of Argonne scientists led by Lorraine LaFreniere injected iron microparticles underneath fields long-polluted with carbon tetrachloride near Centralia, Kansas. The researchers coated the microparticles with organic material, which served as bait for bacteria that created the conditions necessary to safely convert the toxic chemical

We welcome you to The Power of Anaerobes. This conference serves two purposes. One is to celebrate the life of Harry D. Peck, Jr.,who was born May 18, 1927 and would have celebrated his 73rd birthday at this conference. He died November 20, 1998. The second is to gather investigators to exchange views within the realm of anaerobic microbiology, an area in which tremendous progress has been seen during recent years. It is sufficient to mention discoveries of a new form of life (the archaea), hyper or extreme thermophiles, thermophilic alkaliphiles and anaerobic fungi. With these discoveries has come a new realization about physiological and metabolic properties of microorganisms, and this in turn has demonstrated their importance for the development, maintenance and sustenance of life on Earth.

The reduction in viscosity is observed in two complementary experiments: one studying the decay of a large vortex induced by a moving probe and another measuring the viscous torque on a rotating magnetic particle immersed in the film. The viscosity depends on the concentration and swimming speed of the bacteria.

Why sequence Alkaliphilic sulfur oxidizing bacteria for sulfur pollution  

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

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

A carbon steel heat exchanger installed in a reverse osmosis unit failed after 1 1/2 years from start-up as a result of tubes, lids, tube sheets, and connection pipes clogging from rust deposits. Chemical analysis of cooling water and scraped precipitates, as well laboratory screening of the deposits for bacteria, revealed that activity of iron-oxidizing bacteria present in cooling water could lead to heat exchanger blockage.

A wrong molecular turn leads down the path to type 2 diabetes A wrong molecular turn leads down the path to type 2 diabetes By Jen Salazar * December 20, 2013 Tweet EmailPrint Computing resources at the U.S. Department of Energy's (DOE) Argonne National Laboratory have helped researchers better grasp how proteins misfold to create the tissue-damaging structures that lead to type 2 diabetes. 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

Mathematical modelling approach for determining optimal machining parameters in turning with computer numerical control (CNC) machines  

Science Journals Connector (OSTI)

Due to advancement in the manufacturing technology the application of computer numerical control (CNC) machines have increased manifolds. The determination of machining parameters for optimal results in machining is a part of computer aided process planning. In computer numerical control (CNC) machining, determining optimum or appropriate cutting parameters can minimise machining errors such as tool breakage, tool deflection and tool wear, thus yielding a high productivity or minimum cost. Different mathematical models have been proposed by various researchers in the past for the determination of optimal machining parameters. The present paper attempt's to review the literature regarding 'machining parameter optimisation' for turning operation in CNC machines. Diverse contributing and important factors in mathematical modelling like, the economic criteria's, single and multi-pass turning, optimisation techniques and practical constraints deployed have been considered. A detailed discussion is presented regarding the topic and in the end conclusions are drawn.

Experimental Analysis of Work-piece's Diametrical Error in Ultrasonic-Vibration-Assisted Turning  

SciTech Connect

Vibration at an ultrasonic frequency is superimposed on the ordinary cutting motion in ultrasonic-vibration-assisted turning (UAT). This combinatory cutting motion results in reduction of the cutting force and surface roughness, and improvement of the dimensional tolerances compared with conventional turning (CT). The advantages obtainable from UAT has made this process suitable for machining hard-to-cut and brittle materials such as super-alloys and ceramics, as well as ordinary materials. The elastic deflection of work-pieces is primarily responsible for the diametrical errors of the machined parts. This is of course more obvious for slender work-pieces. The influence of UAT process on the diametrical error has not yet been investigated. This has been partly undertaken by the authors of the present paper. It has been experimentally illustrated in this paper that ultrasonic vibration superimposed on the tool tip can result in reduction of the diametrical error and thus reduced scrap rate is ensued.

Has the turning point of China?s wind power industry really come?  

Science Journals Connector (OSTI)

Abstract China?s wind power industry experienced rapid growth before 2009. However, the growing rate slowed down and the problem of wind curtailment was serious recent years. This paper focuses on the analysis of the turning point of China?s wind power industry combing with life circle theory. With a panoramic view of status quo, based on the resource endowment, capacity development and future trends, we draw the following conclusions: (1) China?s potential wind power reserves are still rich and the development of wind power industry will sustain growth for some period in the future. (2) As for market structure aspect, oligopolistic characteristic of China?s wind power market is still obvious. The market share of China?s wind power generation is not very high enough in the total generation market. (3) Turning point of China?s wind power industry has not come yet and the slowing down of development speed at present is mainly caused by inappropriate government intervention. It is estimated the turning point of wind power industry will come around 2020.

Capacity computations of right-turn-on-red using the Highway Capacity Manual  

SciTech Connect

Right-turn-on-red (RTOR) is a traffic control strategy at signalized intersections that allows vehicles to turn right during red phases provided they do not impede the vehicles and pedestrians in green phases. RTOR is primarily a delay and energy conservation measure. Several studies that examined the impact of RTOR on vehicular delays have shown the potential of reducing fuel consumption by about 5 percent on urban streets. The reduction of delay and fuel consumption is related to extra capacity because RTOR allows vehicles to pass through an intersection in red phases. The extra capacity can be significant if an exclusive right-turn lane is provided. The 1985 {ital Highway Capacity Manual} (HCM) provides a powerful technique for evaluating how well an intersection will operate. This technique, however, is less successful in dealing with intersections where RTOR movement is permitted because it requires the analyst to supply RTOR volumes. This situation has led to a need for a formula to compute RTOR capacity. This paper proposes a method to calculate this capacity.

High speed turning for hard material with PCBN inserts: tool wear analysis  

Science Journals Connector (OSTI)

Because of tool wear, High Speed Machining (HSM) is rarely used for hard turning process and the cutting speeds are generally selected around 100 or 200 m/min. In this work, HSM is performed for hard turning of a 50 HRC hardened steel (AISI 4140/42CrMo4) with a PCBN tool by using high cutting speeds (300 and 400 m/min). The results show that HSM for hard turning can be acceptable for industrial application by providing very good surface roughness and keeping significant tool life. A qualitative correlation is also presented between the crater wear and the temperature distribution at the tool-chip interface, predicted by a thermomechanical model. Flank wear, crater wear and surface roughness are examined in order to choose an appropriate wear criterion. Investigations by SEM/EDS and white light interferometry highlight the importance of crater wear and help us to better understand the role of chemical/diffusion phenomena in wear mechanisms.

Evolution of the Kdo2-lipid A Biosynthesis in Bacteria  

SciTech Connect

BACKGROUND: Lipid A is the highly immunoreactive endotoxic center of lipopolysaccharide (LPS). It anchors the LPS into the outer membrane of most Gram-negative bacteria. Lipid A can be recognized by animal cells, triggers defense-related responses, and causes Gram-negative sepsis. The biosynthesis of Kdo2-lipid A, the LPS substructure, involves with nine enzymatic steps. RESULTS: In order to elucidate the evolutionary pathway of Kdo2-lipid A biosynthesis, we examined the distribution of genes encoding the nine enzymes across bacteria. We found that not all Gram-negative bacteria have all nine enzymes. Some Gram-negative bacteria have no genes encoding these enzymes and others have genes only for the first four enzymes (LpxA, LpxC, LpxD, and LpxB). Among the nine enzymes, five appeared to have arisen from three independent gene duplication events. Two of such events happened within the Proteobacteria lineage, followed by functional specialization of the duplicated genes and pathway optimization in these bacteria. CONCLUSIONS: The nine-enzyme pathway, which was established based on the studies mainly in Escherichia coli K12, appears to be the most derived and optimized form. It is found only in E. coli and related Proteobacteria. Simpler and probably less efficient pathways are found in other bacterial groups, with Kdo2-lipid A variants as the likely end products. The Kdo2-lipid A biosynthetic pathway exemplifies extremely plastic evolution of bacterial genomes, especially those of Proteobacteria, and how these mainly pathogenic bacteria have adapted to their environment.

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.

Magnetic Torque of Microfabricated Elements and Magnetotactic Bacteria  

E-Print Network (OSTI)

We present a thorough theoretical analysis of the magnetic torque on microfabricated elements with dimensions in the range of 100 to 500 {\\mu}m and magneto-somes of magnetotactic bacteria of a few {\\mu}m length. We derive simple equations for field dependent torque and magnetic shape anisotropy that can be readily used to replace the crude approximations commonly used. We illustrate and verify the theory on microfabricated elements and magnetotactic bacteria, by field depedent torque magnetometry and by observing their rotation in water under application of a rotating magnetic field. The maximum rotation frequency of the largest microfabricated elements agrees within error boundaries with theory. For smaller, and especially thinner, elements the measured frequencies are a factor of three to four too low. We suspect this is caused by incomplete saturation of the magnetisation in the elements, which is not incorporated in our model. The maximum rotation frequency of magnetotactic bacteria agrees with our model within error margins, which are however quite big due to the large spread in bacteria morphology. The model presented provides a solid basis for the analysis of experiments with magnetic objects in liquid, which is for instance the case in the field of medical microrobotics.

Turning low solar heat gain windows into energy savers in winter  

SciTech Connect

The reduction in summer peak cooling loads of buildings with a large ratio of window to floor areas is often achieved by windows with a low solar heat gain coefficient (SHGC). These windows are typically double glazed with the exterior pane tinted or selectively absorbing. Absorbed solar radiation is rejected to the environment. This is undesirable in the cold season. The authors suggest that by turning south-facing windows by 180{degree} for the duration of the cold season, the solar heat gain of these windows can be increased significantly. By means of a computer simulation, they estimate seasonal energy savings for a model room in several climates. The effect of building heat capacity on the savings is also studied. Windows whose positions can be reversed for ease of cleaning are commercially available. This study shows that in a suitable climate the achievable savings easily compensate for the additional effort and possible investment over the lifetime of the window.

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.

One of the biggest hurdles to achieving this goal lies in optimizing the multistep process involved in breaking down plant biomass and then converting it into fermentable sugars that can be refined into fuel for our transportation needs. To overcome this challenge, the U.S. Department of Energy supports several projects focused on identifying enzymes from fungi and microbes such as cellulases-that breakdown plant cell walls-and heat-tolerant industrial-strength host cell systems to drive these reactions.

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.

Prediction of Cutting Forces Using ANNs Approach in Hard Turning of AISI 52100 steel  

SciTech Connect

In this study, artificial neural networks (ANNs) was used to predict cutting forces in the case of machining the hard turning of AISI 52100 bearing steel using cBN cutting tool. Cutting forces evolution is considered as the key factors which affect machining. Predicting cutting forces evolution allows optimizing machining by an adaptation of cutting conditions. In this context, it seems interesting to study the contribution that could have artificial neural networks (ANNs) on the machining forces prediction in both numerical and experiment studies. Feed-forward multi-layer neural networks trained by the error back-propagation (BP) algorithm are used. Levenberg-Marquardt (LM) optimization algorithm was used for finding out weights. The training of the network is carried out with experimental machining data.The input dataset used are cutting speed, feed rate, cutting depth and hardness of the material. The output dataset used are cutting forces (Ft-cutting force, Fa- feed force and Fr- radial force).Results of the neural networks approach, in comparison with experimental data are discussed in last part of this paper.

Turning green into gold”: a framework for energy performance contracting (EPC) in China's real estate industry  

Science Journals Connector (OSTI)

Abstract There is a growing interest in a sustainable built environment and green technologies are gaining worldwide attention. However, implementing green technologies usually requires more investment than using traditional technologies and the payback period tends to be very long. In China, most developers sell their properties and subsequently transfer the ownership to customers. Hence, a crucial problem for promoting green construction is that developers cannot obtain economic profits (“gold”) from implementing “green” technologies. Meanwhile, other stakeholders, such as property management companies, are also hesitant to adopt green technologies because of the large investment involved and their lack of experience. To tackle this problem, an energy performance contracting (EPC) based framework is proposed, to turn “green” investment into “gold” benefit by careful sharing of the risks existed. The framework was developed by conducting a focus group meeting with three experienced representatives from developer, property management company and energy service company respectively. A real-life case study, which includes both energy efficient system retrofit and new construction, is used to estimate the costs and benefits involved to demonstrate and verify the conceptual framework. The results show that the proposed framework can support the application of green technologies in both types of projects. Economic benefits as well as environmental benefits can be gained for the project stakeholders and the whole society.

Interactions between nitrifying bacteria and hydrocarbon-degrading bacteria during detoxification of oil sands process affected water  

SciTech Connect

Large quantities of process water are produced during the extraction of bitumen from oil sands by the Syncrude and Suncor operations in northern Alberta. Freshly produced tailings water is acutely toxic, but it has been shown to slowly detoxify over time. As detoxification proceeds, there is also a precipitous decrease in ammonia concentrations. The present study examines these two microbially-mediated processes in relation to levels of bacteria and toxicants in mixtures of fresh and aged (detoxified) tailings water. Detoxification of tailings water was greatly accelerated when equal volumes of fresh and detoxified (natural aging for one year) tailings water were mixed. Addition of phosphorus further stimulated detoxification, causing levels of ammonia and naphthenic acids (toxic organic acids leached during bitumen extraction) to decrease to those of detoxified water within two months. Such changes were not observed when phosphorus was not added, or when it was added to less diluted (10-.1 or 3-.1) fresh tailings water. Populations of nitrifying bacteria and naphthenic acid degraders increased markedly in the phosphorus-amended mixtures, but not in its absence. Addition of CS{sub 2} (a specific inhibitor of nitrification) to these mixtures prevented ammonia oxidation. Surprisingly, it also prevented the increase in naphthenic acid-degraders and retarded the loss of naphthenic acids. These results suggest the existence of interactions in fresh tailings water between nitrifying bacteria, naphthenic acid degraders and toxicants. The activity of naphthenic acid-degraders apparently remains low until ammonia is oxidized, whereas that of nitrifying bacteria remains low until concentrations of naphthenic acids or other toxicants decrease below some threshold level. Understanding these interactions may lead to more efficient and effective processes to detoxify oil sands process water.

28. Using Synchroton infrared microspectroscopy to better understand the freezing-resistance of lactic acid bacteria  

Science Journals Connector (OSTI)

Freezing is commonly applied to preserve the functionalities of concentrates of lactic acid bacteria (LAB). However, it is still a critical step in the production of LAB concentrates, as it affects both the viability and acidifying activity upon thawing. Several environmental factors influence the resistance to freezing of LAB (strain, medium composition, temperature, etc.) but the mechanisms of cell injury during freezing need to be elucidated. Cell dehydration taking place during freezing is an important event responsible for alterations of the physical state of membrane lipids and proteins, which, in turn, affect lipid organization and membrane fluidity. FTIR (Fourier Transformed InfraRed) spectroscopy and imaging technology appear to be powerful tools for investigating the biophysical response of LAB and for identifying some key issues in the understanding of the main mechanisms of bacteria degradation during freezing and thawing. In situ and in conditions close to industrial ones, FTIR spectroscopy has recently made it possible to investigate the modifications of the physical state of bacterial lipids of whole cell populations of Lactobacillus delbrueckii subsp. bulgaricus CFL1 (freezing sensitive strain) during freezing and thawing for two different physiological states, corresponding to different behaviours in terms of resistance to freezing and thawing processes. Fresh cells presenting the better resistance to freezing exhibited the lower lipid phase transition temperature, thus remaining in a liquid crystalline state for a longer time during the freezing process (Gautier et al. 2012). This study performed on bacterial suspensions and in real time during freeze–thaw processes, highlighted the difficulties for identifying and quantifying protein conformational changes because of the overlapping of the water band with the protein band. The objective of the present work was to investigate the changes in the secondary structure of proteins of some individual cells of Lb. bulgaricus CFL1 for these two extreme conditions, by using the brilliant Synchrotron infrared beamline SMIS (SOLEIL proposal number 20100789). High reflective index hemispheres (ZnSe) were used in order to get high spatial resolution (2–3 ?m2) making possible the quantification of the population heterogeneity and mapping of biophysical and chemical responses of small groups of cells. Concentrated suspensions of Lb. bulgaricus CFL1 were produced using standard procedure of fermentation in MRS broth or mild whey medium at 42 °C in the biology laboratory of SOLEIL Synchrotron. The bacteria were harvested at the beginning of the stationary phase growth, formulated (addition of protective medium), frozen by immersion in liquid nitrogen and stored at ?20 and ?80 °C. After thawing and washing, cells were dried onto ZnSe hemispheres. ATR (attenuated total reflectance) analysis on the amide I region of dehydrated bacterial suspensions was carried out to examine changes in the protein secondary structures. The impact of the physiological state (viability and acidifying activity) on cell biophysical behaviour and freezing-resistance was investigated by analysing samples before and after each storage conditions. Better resistance to freezing, characterized by a higher acidifying activity and cell survival, was observed for cells presenting a higher proportion of proteins in ?-helix conformation. Furthermore, a study of the impact of freezing on the protein secondary structures is in progress.

Biofuels from Bacteria, Electricity, and CO2: Biofuels from CO2 Using Ammonia or Iron-Oxidizing Bacteria in Reverse Microbial Fuel Cells  

SciTech Connect

Electrofuels Project: Electrofuels Project: Columbia University is using carbon dioxide (CO2) from ambient air, ammonia—an abundant and affordable chemical, and a bacteria called N. europaea to produce liquid fuel. 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 system—creating 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.

Removal of Heavy Metals from Industrial Effluent Using Bacteria  

E-Print Network (OSTI)

Industrial development results in the generation of industrial effluents, and if untreated results in water, sediment and soil pollution. (Fakayode and Onianwa, 2002 ? Fakayode, 2005). Industrial wastes and emission contain toxic and hazardous substances, most of which are detrimental to human health (Jimena et al.,2008 ? Ogunfowokan et al.,2005 ? Rajaram et al.,2008). The key pollutants include heavy metals, chemical wastes and oil spills etc. Heavy metal resistant bacteria have significant role in bioremediation of heavy metals in wastewater. The objective of this work is to study the role of bacteria in removing the heavy metals present in the industrial effluent.Five effluent samples out of nine were selected for this study due to high content of heavy metals. The heavy metals Hg and Cu were removed by Bacillus sp. The average Hg reduction was 45 % and Cu reduction was recorded as 62%. The heavy metals Cd, As and Co were removed by Pseudomonas sp. The average Cd reduction was 56%, average As reduction was 34 % and average Co reduction was recorded as 53%. The heavy metals Cd and Cu were removed by Staphylococcus sp. The average Cd reduction was 44 % and average Cu reduction was recorded as 34 %.

Interaction of Plutonium with Bacteria in the Repository Environment  

SciTech Connect

Microorganisms in the nuclear waste repository environment may interact with plutonium through (1) sorption, (2) intracellular accumulation, and (3) transformation speciation. These interactions may retard or enhance the mobility of Pu by precipitation reactions, biocolloid formation, or production of more soluble species. Current and planned radioactive waste repository environments, such as deep subsurface halite and granite formations, are considered extreme relative to life processes in the near-surface terrestrial environment. There is a paucity of information on the biotransformation of radionuclides by microorganisms present in such extreme environments. In order to gain a better understanding of the interaction of plutonium with microorganisms present in the waste repository sites we investigated a pure culture (Halomonas sp.) and a mixed culture of bacteria (Haloarcula sinaiiensis, Marinobacter hydrocarbonoclasticus, Altermonas sp., and a {gamma}-proteobacterium) isolated from the Waste Isolation Pilot Plant (WIPP) site and an Acetobacterium sp. from alkaline groundwater at the Grimsel Test Site in Switzerland.

CEMs turn monitoring giant  

SciTech Connect

Crucial to complying with environmental regulations is selecting appropriate pollution control equipment to capture or destroy regulated pollutants. But just as important is selecting a continuous emissions monitoring system (CEM). CEMs play a dual role in an overall compliance strategy. On one hand, they identify the type and quantity of emissions at a source as a first step for determining which regulatory requirements and control technologies are applicable. They also provide ongoing emissions data to demonstrate compliance with air and other environmental regulations. Facilities are required to monitor their processes with CEMs, or a comparable technology, under several titles of the Clean Air Act Amendments of 1990. CEMs meet regulatory requirements if they include a SO[sub 2] concentration monitor, nitrogen oxides (NO[sub x]) concentration monitor, volumetric flow monitor, opacity monitor, diluent gas monitor and data acquisition and handling system. The entire system and each subsystem has to be installed and certified before it can be used for compliance. A written quality assurance/quality control (QA/QC) plan for the CEMs must accompany the permit application. The acid rain rules also impose performance standards and frequent calibration checks to ensure the integrity of CEMs data.

Detailed design of a 13 kA 13 kV dc solid-state turn-off switch  

SciTech Connect

An experimental facility for the study of electromagnetic effects in the First Wall-Blanket-shield (FWBS) systems of fusion reactors has been constructed at Argonne National Laboratory (ANL). In a test volume of 0.76 m/sup 3/, a vertical, pulsed 5 kG dipole field (B < 320 kGs/sup -1/) is perpendicular to a 10 kG solenoid field. Power supplies of 2.75 MW at 550 V dc and 5.5 MW at 550 V dc and a solid-state switch rated at 13 kA and 13 kV (169 MW) control the pulsed magnetic fields. The total stored energy in the coils is 2.6 MJ. This paper describes the design and construction features of the solid-state switching circuit which turns off a dc of 13 kA in approximately 82 ..mu..s and holds off voltages of < 13 kV.

Fault detection for stator inter-turn short circuit in doubly fed induction generators using adaptive observers  

Science Journals Connector (OSTI)

This paper presents an observer-based fault detection approach for inter-turn stator short circuit fault in doubly fed induction generators (DFIG). A state-space model is developed, which can represent both the healthy and faulty conditions. Based on this model, two different adaptive observers: asymptotic adaptive observer and exponential adaptive observer are constructed, which are both able to estimate the fraction of short circuited winding online. The case when the rotor speed is immeasurable is also considered in this paper. The proposed exponential adaptive observer is reformulated into a new observer, which is capable of estimating the fault level and the rotor speed simultaneously. The simulation results demonstrate that this approach has effectiveness on fault detection under both steady state operation and transient state operation. It has strong robustness against the speed and load variations. This advantage has significance on fault detection of wind turbine DFIGs, since the DFIGs are predominantly under varying speed operation.

Data Gathering in Networks of Bacteria Colonies: Collective Sensing and Relaying Using Molecular Communication  

E-Print Network (OSTI)

The prospect of new biological and industrial applications that require communication in micro-scale, encourages research on the design of bio-compatible communication networks using networking primitives already available in nature. One of the most promising candidates for constructing such networks is to adapt and engineer specific types of bacteria that are capable of sensing, actuation, and above all, communication with each other. In this paper, we describe a new architecture for networks of bacteria to form a data collecting network, as in traditional sensor networks. The key to this architecture is the fact that the node in the network itself is a bacterial colony; as an individual bacterium (biological agent) is a tiny unreliable element with limited capabilities. We describe such a network under two different scenarios. We study the data gathering (sensing and multihop communication) scenario as in sensor networks followed by the consensus problem in a multi-node network. We will explain as to how th...

Modeling the role of bacteria in leaching of low-grade ores  

SciTech Connect

A robustious structural model is developed to describe the role of bacteria in the leaching process of low-grade ores under conditions controlled by intraparticle diffusion. The main impetus behind developing this model is to provide an insight into such systems, together with a suitable framework for interpreting experimental data. The model is derived in detail with respect to reaction chemistry and the role of bacteria in catalyzing these reactions, specifically the synergism of chemistry, physics and biology in determining the overall behavior of the system. The model is used to simulate the atmospheric oxidation of iron disulfide contained in porous solids in the presence of Thiobacillus ferrooxidans (T. ferrooxidans). The experimental data are predicted well by the model, which demonstrates its applicability and supports the view that the rate of intraparticle diffusion is the controlling mechanism for this system.

Application of response surface methodology to evaluate the effect of cutting tool inserts on machining of aluminium 7075 alloy on CNC turning centre  

Science Journals Connector (OSTI)

In this paper, the main emphasis is on the study of machinability of aluminium alloy 7075 with the prime objective to ascertain the minimum tangential force and fine surface roughness. Series of tests were conducted in order to investigate the machinability with the objective to study the performance of different tool materials PCD and carbide. The utmost attention was taken in selecting the test material, tool geometry and cutting parameters for turning of material. The main factors deciding the above objective are cutting speed, feed rate, depth of cut and approach angle. Here, an attempt had been made to model the machinability evaluation through face centred CCD of Response surface method. The experimental results indicate that the proposed mathematical model suggested could adequately describe the performance of the factors that are being investigated. The results indicate that the polycrystalline diamond tool provide satisfactory results with better tool life than carbide tool at high speed turning. Moreover, the cost of (PCD) tools could be absolved by using dry cutting at high turning parameters. Optimum cutting conditions produced from DOE are verified with the experimental measurement.

Mechanisms regulating the reduction of selenite by aerobic gram (+) and ({minus}) bacteria  

SciTech Connect

Toxic species of selenium are pollutants found in agricultural and oil refinery wastestreams. Selenium contamination is particularly problematic in areas that have seleniferous subsurface geology, such as the central valley of California. The authors are developed a bacterial treatment system to mitigate selenium-contaminated wastestreams using Bacillus subtilis and Pseudomonas fluorescens, respectively, as model gram (+) and ({minus}) soil bacteria. They have found that, during growth, both organisms reduce selenite, a major soluble toxic species, to red elemental selenium--an insoluble product generally regarded as nontoxic. In both cases, reduction depended on growth substrate and was effected by an inducible system that effectively removed selenite at concentrations typical of polluted sites--i.e., 50 to 300 {micro}g/L. The bacteria studied differed in one respect: when grown in medium supplemented with nitrate or sulfate, the ability of P. fluorescens to remediate selenite was enhanced, whereas that of B. subtilis was unchanged. Current efforts are being directed toward understanding the biochemical mechanism(s) of detoxification and determining whether bacteria occurring in polluted environments such as soils and sludge systems are capable of selenite remediation.

Environmental diagnostic analysis of ground water bacteria and their involvement in utilization of aromatic compounds  

SciTech Connect

The objective of this study was to examine the hypothesis that select functional groups of bacteria from pristine sites have an innate ability to degrade synthetic aromatics that often contaminate groundwater environments,due to exposure to naturally occurring recalcitrant aromatics in their environment. This study demonstrates that subsurface microbial communities are capable of utilizing lignin and humic acid breakdown products. Utilizers of these compounds were found to be present in most all the wells tested. Even the deepest aquifer tested had utilizers present for all six of the aromatics tested. Highest counts for the aromatics tested were observed with the naturally occurring breakdown products of either lignin or humic acid. Carboxylic acids were found to be an important sole carbon source for groundwater bacteria possibly explained by the fact that they are produced by the oxidative cleavage of aromatic ring structures. The carbohydrate sole carbon sources that demonstrated the greatest densities were ones commonly associated with humics. This study indicates that utilization of naturally occurring aromatic compounds in the subsurface is an important nutritional source for groundwater bacteria. In addition, it suggests that adaptation to naturally occurring recalcitrant substrates is the origin of degradative pathways for xenobiotic compounds with analogous structure. This work has important implications for in situ bioremediation as a method of environmental cleanup.

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  

SciTech Connect

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.

The Mannitol Operon Repressor MTIR belongs to a new class of transcription regulators in bacteria.  

SciTech Connect

Many bacteria express phosphoenolpyruvate-dependent phosphotransferase systems (PTS). The mannitol-specific PTS catalyze the uptake and phosphorylation of d-mannitol. The uptake system comprises several genes encoded in the single operon. The expression of the mannitol operon is regulated by a proposed transcriptional factor, mannitol operon repressor (MtlR) that was first studied in Escherichia coli. Here we report the first crystal structures of MtlR from Vibrio parahemeolyticus (Vp-MtlR) and its homolog YggD protein from Shigella flexneri (Sf-YggD). MtlR and YggD belong to the same protein family (Pfam05068). Although Vp-MtlR and Sf-YggD share low sequence identity (22%), their overall structures are very similar, representing a novel all {alpha}-helical fold, and indicate similar function. However, their lack of any known DNA-binding structural motifs and their unfavorable electrostatic properties imply that MtlR/YggD are unlikely to bind a specific DNA operator directly as proposed earlier. This structural observation is further corroborated by in vitro DNA-binding studies of E. coli MtlR (Ec-MtlR), which detected no interaction of Ec-MtlR with the well characterized mannitol operator/promoter region. Therefore, MtlR/YggD belongs to a new class of transcription factors in bacteria that may regulate gene expression indirectly as a part of a larger transcriptional complex.

Final technical report: The effect of physical and chemical heterogeneities in a porous medium on the transport of bacteria  

SciTech Connect

Among the demonstrated processes influencing the transport of bacteria through aquifers, the deposition of cells on mineral surfaces is one of the most important. Heterogeneous distribution of aquifer properties such as mineral-grain oxide coatings and preferred flow paths can control the numbers of microbes arriving a point down gradient from their injection, and these properties can also affect the distribution of the organisms remaining in the sedimentary matrix. The distribution of metal oxide coatings affects the final location of retained cells within the matrix but had no effect on total breakthrough of applied bacteria. We were able to demonstrate transverse mixing of both conservative tracers and bacteria between regions of differing hydraulic conductivity; the conservative tracer could be used to model the transverse mixing of the bacteria. We were able to show that the presence of metal oxide coatings on aquifer surfaces retarded a reactive tracer (SO{sub 4}{sup 2-}) that simulated bacterial retardation in the laboratory. When metal oxide coatings were absent (due to bacterial establishment of a reducing environment) the tracer and bacteria were not retarded. The effect was reproduced in a tracer experiment done in the field. The results suggest that bacterial transport in the subsurface is controlled by a number of interrelated and confounding factors that prevent accurate prediction of transport given the present state of knowledge.

Triclosan causes toxic effects to algae in marine biofilms, but does not inhibit the metabolic activity of marine biofilm bacteria  

Science Journals Connector (OSTI)

Abstract Effects of the antimicrobial agent triclosan to natural periphyton communities (biofilms, comprising primarily microalgae and bacteria) were assessed in two independent experiments during spring and summer. For that purpose a semi-static test system was used in which periphyton was exposed to a concentration range of 5–9054 nmol/L triclosan. Effects on algae were analyzed as content and composition of photosynthetic pigments. The corresponding EC50 values were 39.25 and 302.45 nmol/L for the spring and summer experiment, respectively. Effects on periphytic bacteria were assessed as effects on carbon utilization patterns, using Biolog Ecoplates. No inhibition of either total carbon utilization or functional diversity was observed, indicating a pronounced triclosan tolerance of the marine bacteria. In contrast, a small stimulation of the total carbon utilization was observed at triclosan concentrations exceeding 100 nmol/L.

Effects of pretreatment method of natural bacteria source on microbial community and bio-hydrogen production by dark fermentation  

Science Journals Connector (OSTI)

The effects of pretreatment method of cow dung compost, which was employed as natural hydrogen bacteria source, on the microbial community, population distribution of microbes and hydrogen production potential were investigated in the batch tests. The maximum hydrogen yield of 290.8 mL/L-culture appeared in the pretreated method A (infrared drying) by dark fermentation. The pretreated method of compost significantly affected microbial succession, population distribution of microbes. Both Clostridium sp. and Enterobacter sp. were found to be two species of preponderant hydrogen-producing bacteria, the next best was Bacteroides sp. and Veillonella sp., the last was Lactobacillus sp. and Streptococcus sp., which were also essential. The results showed that the mutualism and symbiosis relations of the mixed bacteria played a critical role in hydrogen fermentation process.

Bacterias patógenas con alta resistencia a antibióticos: estudio sobre reservorios bacterianos en animales cautivos en el zoológico de Barranquilla  

Science Journals Connector (OSTI)

AbstractObjective The objective is to determine respiratory and enteric bacterial pathogens and antimicrobial susceptibility in captive animals at Barranquilla Zoo. Materials and methods Samples were taken from rectus and glottis in 30 birds and nasal and rectal swabs from 29 mammals, which were restricted mechanically and then anesthetized. Bacteria were identified by using biochemical tests such as: Urea, SIM, TSI, LIA and Citrate, some bacteria isolates were confirmed with API 20E (Biomerieux SA, Marcy I’Etoile, France) or Micro scan® Neg combo panel type 32 (Dade Behring, CA, USA). Antimicrobial susceptibility was assessed using the Bauer and Kirby method and taking into account CLSI regulation. Results Eighty-nine strains were obtained, 45 from birds and 44 from mammals. The most frequent bacteria were: E. coli (n = 31), Klebsiella pneumoniae (n = 20), Enterobacter cloacae (n = 10), Pseudomonas aeruginosa (n = 5), Staphylococcus aureus (n = 5) and Pseudomonas stuzeri (n = 4). Gram negative bacteria and Staphylococci were respectively resistant to the following antibiotics: tetracycline (28% and 57.1%), chloramphenicol (14.6% and 57.1%) and ?-lactam (54.2% and 42.8); Gram-negative was (6.1%) resistant to Fluorquinolones and (2.4%) resistant to aminoglycosides; and Staphylococci were (64.2%) resistant to macrolides. Twentyfour (27%) were multi-resistant: 16 (36%) in birds and 8 (18%) in mammals. Conclusion Resistance to one or more antibiotics in bacteria isolated from captive animals Barranquilla Zoo, is a risk factor for health for the animals themselves. The zoo animals are potential reservoirs for bacteria and resistance genes clinically important in the spread of these resistance factors. The resistance similarities found in animal and human strains suggest clone mobility between the sapiens species and the animals.

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)

Neptunium(V) adsorption to bacteria at low and high ionic strength  

SciTech Connect

Np(V) is expected to be the predominant oxidation state of neptunium in aerobic natural waters. Np(V), as the NpO{sub 2}{sup +} aquo and associated complexed species, is readily soluble, weakly interacting with geologic media, and has a high redox stability under a relatively wide range of subsurface conditions. These chemical properties, along with a long half-life make it a primary element of concern regarding long-term nuclear waste storage and subsurface contaminant. The fate and transport of neptunium in the environment may be influenced by adsorption onto bacterial surfaces. The adsorption of neptunium to bacterial surfaces ties the mobility of the contaminant to the mobility of the bacterium. In this study, the adsorption of the neptunyl (NpO{sub 2}{sup +}) ion was evaluated at low ionic strength on a common soil bacterium and at high ionic strength on a halophilic bacterium isolated from a briny groundwater near the Waste Isolation Pilot Plant (WIPP) in southeast New Mexico. Adsorption experiments were performed in batch reactors as a function of pH, ionic strength, and bacterialNp mass ratio. Np(V) adsorption was modeled using a surface complexation approach with the mathematical program FITEQL to determine functional group specific binding constants. The data from acid and base titrations of the bacteria were also modeled to estimate the concentrations and deprotonation constants of discrete bacterial surface functional groups. Bacterial functional group characteristics and Np(V) adsorption behavior between the soil bacterium and the halophilic bacterium were compared. These results highlight the key similarities and differences in actinide adsorption behavior in environments of significantly different ionic strength. Similarities in adsorption behavior may be linked to similarities in the characteristics of the moieties between all bacterial cell walls. Differences in adsorption behavior may reflect differences in ionic strength effects, rather than differences in bacteria type, as the electronic double layer is compressed with increasing ionic strength. These results further highlight the importance of electrostatic interactions in the adsorption process between dissolved metals and bacterial surfaces. This work expands the understanding of actinide-bacteria adsorption phenomena to high ionic strength environmental conditions that are relevant as an aid to predicting Np(V) fate and transport behavior in areas such as the vicinity of salt-based nuclear waste repositories and high ionic-strength deep ground waters at DOE sites.

Stuttering Min oscillations within E. coli bacteria: a stochastic polymerization model  

E-Print Network (OSTI)

We have developed a 3D off-lattice stochastic polymerization model to study subcellular oscillation of Min proteins in the bacteria Escherichia coli, and used it to investigate the experimental phenomenon of Min oscillation stuttering. Stuttering was affected by the rate of immediate rebinding of MinE released from depolymerizing filament tips (processivity), protection of depolymerizing filament tips from MinD binding, and fragmentation of MinD filaments due to MinE. Each of processivity, protection, and fragmentation reduces stuttering, speeds oscillations, and reduces MinD filament lengths. Neither processivity or tip-protection were, on their own, sufficient to produce fast stutter-free oscillations. While filament fragmentation could, on its own, lead to fast oscillations with infrequent stuttering; high levels of fragmentation degraded oscillations. The infrequent stuttering observed in standard Min oscillations are consistent with short filaments of MinD, while we expect that mutants that exhibit highe...

Control filamentous bulking caused by chlorine-resistant Type 021N bacteria through adding a biocide CTAB  

Science Journals Connector (OSTI)

Filamentous bulking sludge due to excessive growth of filamentous bacteria is a serious operational problem in activated sludge plants. The addition of chemicals is one of widespread ways to control filamentous bulking. In this study, filamentous bulking in a continuous activated sludge system was found to be mainly caused by Eikelboom Type 021N filamentous bacteria likely due to low substrate concentration gradients. These Type 021N bacteria were found to be resistant to chlorination, maintaining cell integrity at a dosage of up to 80 mg Cl/gSS. An alternative biocidal agent, cetyltrimethyl ammonium bromide (CTAB), exhibited a much stronger biocidal effect on these filaments, which significantly improved sludge settleability. Type 021N with filamentous index of 5 was selectively killed, but floc-formers recovery their activity after CTAB termination. The study implied that CTAB might have more penetration capacity to cell wall of chlorine-resistant Type 021N bacteria. We therefore suggest the penetration property of filament cell wall should be considered or tested before the selection of biocide type in practice.

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.

Dissimilatory Metabolism of Nitrogen Oxides in Bacteria:Comparative Reconstruction of Transcriptional Networks  

SciTech Connect

Bacterial response to nitric oxide (NO) is of major importance since NO is an obligatory intermediate of the nitrogen cycle. Transcriptional regulation of the dissimilatory nitric oxides metabolism in bacteria is diverse and involves FNR-like transcription factors HcpR, DNR and NnrR, two-component systems NarXL and NarQP, NO-responsive activator NorR, and nitrite sensitive repressor NsrR. Using comparative genomics approaches we predict DNA-binding signals for these transcriptional factors and describe corresponding regulons in available bacterial genomes. Within the FNR family of regulators, we observed a correlation of two specificity-determining amino acids and contacting bases in corresponding DNA signal. Highly conserved regulon HcpR for the hybrid cluster protein and some other redox enzymes is present in diverse anaerobic bacteria including Clostridia, Thermotogales and delta-proteobacteria. NnrR and DNR control denitrification in alpha- and beta-proteobacteria, respectively. Sigma-54-dependent NorR regulon found in some gamma- and beta-proteobacteria contains various enzymes involved in the NO detoxification. Repressor NsrR, which was previously known to control only nitrite reductase operon in Nitrosomonas spp., appears to be the master regulator of the nitric oxides metabolism not only in most gamma- and beta-proteobacteria (including well-studied species like Escherichia coli), but also in Gram-positive Bacillus and Streptomyces species. Positional analysis and comparison of regulatory regions of NO detoxification genes allows us to propose the candidate NsrR-binding signal. The most conserved member of the predicted NsrR regulon is the NO-detoxifying flavohemoglobin Hmp. In enterobacteria, the regulon includes also two nitrite-responsive loci, nipAB (hcp-hcr) and nipC(dnrN), thus confirming the identity of the effector, i.e., nitrite. The proposed NsrR regulons in Neisseria and some other species are extended to include denitrification genes. As the result, we demonstrate considerable interconnection between various nitrogen-oxides-responsive regulatory systems for the denitrification and NO detoxification genes and evolutionary plasticity of this transcriptional network.

Changes in Translational Efficiency is a Dominant Regulatory Mechanism in the Environmental Response of Bacteria  

SciTech Connect

To understand how cell physiological state affects mRNA translation, we used Shewanella oneidensis MR-1 grown under steady state conditions at either aerobic or suboxic conditions. Using a combination of quantitative proteomics and RNA-Seq, we generated high-confidence data on >1000 mRNA and protein pairs. By using a steady state model, we found that differences in protein-mRNA ratios were primarily caused by differences in the translational efficiency of specific genes. When oxygen levels were lowered, 28% of the proteins showed at least a 2-fold change in expression. Altered transcription levels appeared responsible for 26% of the protein changes, altered translational efficiency appeared responsible for 46% and a combination of both were responsible for the remaining 28%. Changes in translational efficiency were significantly correlated with the codon usage pattern of the genes and measurable tRNA pools changed in response to altered O2 levels. Our results suggest that changes in the translational efficiency of proteins, in part caused by altered tRNA pools, is a major determinant of regulated protein expression in bacteria.

Stuttering Min oscillations within E. coli bacteria: A stochastic polymerization model  

E-Print Network (OSTI)

We have developed a 3D off-lattice stochastic polymerization model to study subcellular oscillation of Min proteins in the bacteria Escherichia coli, and used it to investigate the experimental phenomenon of Min oscillation stuttering. Stuttering was affected by the rate of immediate rebinding of MinE released from depolymerizing filament tips (processivity), protection of depolymerizing filament tips from MinD binding, and fragmentation of MinD filaments due to MinE. Each of processivity, protection, and fragmentation reduces stuttering, speeds oscillations, and reduces MinD filament lengths. Neither processivity or tip-protection were, on their own, sufficient to produce fast stutter-free oscillations. While filament fragmentation could, on its own, lead to fast oscillations with infrequent stuttering; high levels of fragmentation degraded oscillations. The infrequent stuttering observed in standard Min oscillations are consistent with short filaments of MinD, while we expect that mutants that exhibit higher stuttering frequencies will exhibit longer MinD filaments. Increased stuttering rate may be a useful diagnostic to find observable MinD polymerization in experimental conditions.

Bacteria-mediated in vivo delivery of quantum dots into solid tumor  

SciTech Connect

Highlights: Black-Right-Pointing-Pointer New approach using the probiotic Bifidobacterium bifidum as a vehicle to deliver QDs into the deep tissue of solid tumors in vivo was achieved. Black-Right-Pointing-Pointer Bifidobacterium bifidum delivery system has intrinsic biocompatibility. Black-Right-Pointing-Pointer The targeting efficacy was improved by folic acids. -- Abstract: Semiconductor nanocrystals, so-called quantum dots (QDs), promise potential application in bioimaging and diagnosis in vitro and in vivo owing to their high-quality photoluminescence and excellent photostability as well as size-tunable spectra. Here, we describe a biocompatible, comparatively safe bacteria-based system that can deliver QDs specifically into solid tumor of living animals. In our strategy, anaerobic bacterium Bifidobacterium bifidum (B. bifidum) that colonizes selectively in hypoxic regions of animal body was successfully used as a vehicle to load with QDs and transported into the deep tissue of solid tumors. The internalization of lipid-encapsuled QDs into B. bifidum was conveniently carried by electroporation. To improve the efficacy and specificity of tumor targeting, the QDs-carrying bacterium surface was further conjugated with folic acids (FAs) that can bind to the folic acid receptor overexpressed tumor cells. This new approach opens a pathway for delivering different types of functional cargos such as nanoparticles and drugs into solid tumor of live animals for imaging, diagnosis and therapy.

Capability of air filters to retain airborne bacteria and molds in heating, ventilating and air-conditioning (HVAC) systems  

Science Journals Connector (OSTI)

The capability of air filters (filterclass: F6, F7) to retain airborne outdoor microorganisms was examined in field experiments in two heating, ventilating and air conditioning (HVAC) systems. At the beginning of the 15-month investigation period, the first filter stages of both HVAC systems were equipped with new unused air filters. The number of airborne bacteria and molds before and behind the filters were determined simultaneously in 14 days-intervals using 6-stage Andersen cascade impactors. Under relatively dry ( 12 °C) outdoor air conditions air filters led to a marked reduction of airborne microorganism concentrations (bacteria by approximately 70 % and molds by > 80 %). However, during long periods of high relative humidity (> 80 % R. H.) a proliferation of bacteria on air filters with subsequent release into the filtered air occured. These microorganisms were mainly smaller than 1.1 ?m therefore being part of the respirable fraction. The results showed furthermore that one possibility to avoid microbial proliferation is to limit the relative humidity in the area of the air filters to 80 % R. H. (mean of 3 days), e. g. by using preheaters in front of air filters in HVAC-systems.

Human health risk implications of multiple sources of faecal indicator bacteria in a recreational waterbody  

Science Journals Connector (OSTI)

Abstract We simulate the influence of multiple sources of enterococci (ENT) as faecal indicator bacteria (FIB) in recreational water bodies on potential human health risk by considering waters impacted by human and animal sources, human and non-pathogenic sources, and animal and non-pathogenic sources. We illustrate that risks vary with the proportion of culturable ENT in water bodies derived from these sources and estimate corresponding ENT densities that yield the same level of health protection that the recreational water quality criteria in the United States seeks (benchmark risk). The benchmark risk is based on epidemiological studies conducted in water bodies predominantly impacted by human faecal sources. The key result is that the risks from mixed sources are driven predominantly by the proportion of the contamination source with the greatest ability to cause human infection (potency), not necessarily the greatest source(s) of FIB. Predicted risks from exposures to mixtures comprised of approximately 30% ENT from human sources were up to 50% lower than the risks expected from purely human sources when contamination is recent and ENT levels are at the current water quality criteria levels (35 CFU 100 mL-1). For human/non-pathogenic, human/gull, human/pig, and human/chicken faecal mixtures with relatively low human contribution, the predicted culturable enterococci densities that correspond to the benchmark risk are substantially greater than the current water quality criteria values. These findings are important because they highlight the potential applicability of site specific water quality criteria for waters that are predominantly un-impacted by human sources.

Comparing the effect of digestate and chemical fertiliser on soil bacteria  

Science Journals Connector (OSTI)

Abstract Different fertilisation regimes, i.e. the use of inorganic or organic fertilisers used in agriculture, are thought to cause differential effects on soil bacteria. In this study, glasshouse experiments were used to test the effects caused by addition of inorganic fertiliser or digestate from sewage sludge on soil bacterial community structure and diversity assessed by pyrosequencing of the V1–V3 region of the 16S rRNA gene. Spring wheat (Triticum aestivum L., cultivar Paragon) was used as model crop and its growth (measured by total dry weight) was monitored as well as changes in soil nitrogen and phosphorous at three time points over 128 days. Overall, 40 different bacterial phyla were detected with Proteobacteria, Acidobacteria and Actinobacteria dominating the communities. Additionally, members of the Bacteroidetes, Gemmatimonadetes, Chloroflexi and WS3 were found in all samples. Members of the Planctomycetes, Firmicutes, Nitrospirae, candidate division SPAM and Armatimonadetes were found in all samples but at lower abundances. Within the phylum Proteobacteria the classes Alpha- and Betaproteobacteria were most prevalent. Over the course of the experiment, the major differences between treatments were observed for the Actino-, Proteo- and the Acidobacteria. Sequences related to the Planctomycetes, implicated in nitrogen cycling, decreased in all treatments during the course of the experiment. Statistical analyses revealed that mainly nutrient addition and plant growth influenced the bacterial community structure. The effects of the treatment itself could be attributed to different gain in wheat growth especially when the communities were compared at the end of the trial. Our results indicate that the usage of different fertilisers will not only affect the bacterial community by direct addition of nutrients, but also indirectly.

Lithotrophic iron-oxidizing bacteria produce organic stalks to control mineral growth: implications for biosignature formation  

SciTech Connect

Neutrophilic Fe-oxidizing bacteria (FeOB) are often identified by their distinctive morphologies, such as the extracellular twisted ribbon-like stalks formed by Gallionella ferruginea or Mariprofundus ferrooxydans. Similar filaments preserved in silica are often identified as FeOB fossils in rocks. Although it is assumed that twisted iron stalks are indicative of FeOB, the stalk's metabolic role has not been established. To this end, we studied the marine FeOB M. ferrooxydans by light, X-ray and electron microscopy. Using time-lapse light microscopy, we observed cells excreting stalks during growth (averaging 2.2 {micro}m h(-1)). Scanning transmission X-ray microscopy and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy show that stalks are Fe(III)-rich, whereas cells are low in Fe. Transmission electron microscopy reveals that stalks are composed of several fibrils, which contain few-nanometer-sized iron oxyhydroxide crystals. Lepidocrocite crystals that nucleated on the fibril surface are much larger ({approx}100 nm), suggesting that mineral growth within fibrils is retarded, relative to sites surrounding fibrils. C and N 1s NEXAFS spectroscopy and fluorescence probing show that stalks primarily contain carboxyl-rich polysaccharides. On the basis of these results, we suggest a physiological model for Fe oxidation in which cells excrete oxidized Fe bound to organic polymers. These organic molecules retard mineral growth, preventing cell encrustation. This model describes an essential role for stalk formation in FeOB growth. We suggest that stalk-like morphologies observed in modern and ancient samples may be correlated confidently with the Fe-oxidizing metabolism as a robust biosignature.

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.

Bisulfite reductase and nitrogenase genes retrieved from biocorrosive bacteria in saline produced waters of offshore oil recovery facilities  

Science Journals Connector (OSTI)

Water-flooding is a common strategy to enhance oil recovery in reservoirs. Maintaining quality and standards of produced water avoids oil biodegradation, biogenic souring and biocorrosion during operations, which are influenced by sulfate-reducing (SRB) and Fe (III) reducing bacteria. The aim of this work was to increase our knowledge of corrosive bacterial communities inhabiting saline produced waters of offshore oil exploitation facilities through retrieving sequences of functional genes, for instance, dsrAB and nifD of Desulfovibrionales, Desulfobacterales and Desulfuromonadales taxonomical orders. Five clone libraries were generated with retrieved sequences acquired from different saline produced waters, with and without biocide dosing. The dsrAB phylogenetic analyses showed Desulfomicrobium, Desulfovibrio, and Desulfohalobium as well as Desulfococcus, Desulfosarcina, Desulfobacter, Desulfobacterium and Desulfobulbus. The retrieved nifD genes displayed the Fe (III) reducing bacteria (Desulfuromonadales) such as Desulfuromusa, Pelobacter, Malonomonas, and Desulfuromonas. The relative abundance in all waters was: the Desulfovibrionales were represented by 55.28% of analyzed clones; the Desulfobacterales by 26.83% and 17.89% for the Desulfuromonadales. Diversity measures were calculated by the Shannon index (H?), which showed that there was a high degree of diversity between all produced waters; however, dominance in produced water with biocide was detected by a Desulfovibrio taxon.

Assessing the yield, microstructure, and texture properties of miniature Chihuahua-type cheese manufactured with a phospholipase A1 and exopolysaccharide-producing bacteria  

Science Journals Connector (OSTI)

Abstract Chihuahua cheese or Mennonite cheese is one of the most popular and consumed cheeses in Mexico and by the Hispanic community in the United States. According to local producers the yield of Chihuahua cheese ranges from 9 to 9.5 kg of cheese from 100 kg of milk. Cheese yield is a crucial determinant of profitability in cheese-manufacturing plants; therefore, different methods have been developed to increase it. In this work, a miniature Chihuahua-type cheese model was used to assess the effect of a phospholipase A1 (PL-A1) and exopolysaccharide (EPS)-producing bacteria (separately and in combination) on the yield, microstructure, and texture of cheese. Four different cheeses were manufactured: cheese made with PL-A1, cheese made with EPS-producing bacteria, cheese with both PL-A1 and EPS-producing bacteria, and a cheese control without PL-A1 or EPS-producing bacteria. The compositional analysis of cheese was carried out using methods of AOAC International (Washington, DC). The actual yield and moisture-adjusted yield were calculated for all cheese treatments. Texture profile analyses of cheeses were performed using a texture analyzer. Micrographs were obtained by electron scanning microscopy. Fifty panelists carried out sensorial analysis using ranking tests. Incorporation of EPS-producing bacteria in the manufacture of cheese increased the moisture content and water activity. In contrast, the addition of PL-A1 did not increase fat retention or cheese yield. The use of EPS alone improved the cheese yield by increasing water and fat retention, but also caused a negative effect on the texture and flavor of Chihuahua cheese. The use of EPS-producing bacteria in combination with PL-A1 improved the cheese yield and increased the moisture and fat content. The cheeses with the best flavor and texture were those manufactured with PL-A1 and the cheeses manufactured with the combination of PL-A1 and EPS-producing culture.

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

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.

Single-cell analysis of growth in budding yeast and bacteria reveals a common size regulation strategy  

E-Print Network (OSTI)

Unicellular organism from various kingdoms of life face the challenge of regulating their size. Despite decades of research, we still do not have a good understanding of the molecular mechanisms involved in this regulation, and how cells coordinate the different events of the cell cycle, such as growth, division and DNA replication is still unclear. Here, we report on experimental results for the budding yeast Saccharomyces cerevisiae and the bacterium Escherichia coli, showing that, remarkably, they share a common strategy for cell size control. We collected data on single-cell growth and cell cycle progression in S. cerevisiae in several growth media and estimated the distributions of size at birth and interdivision time as well as their correlations throughout cell lineages. We also performed the same analysis on previously collected data on single-cell growth and division in E. coli. The results are in quantitative agreement with the predictions of the incremental model, which leads to the addition of a constant volume (up to fluctuations), independent of size at birth, between birth and division; we show that in both organisms size at birth and size at division exhibit a linear relationship with slope one. This result, together with extended additional analysis supporting the incremental model, argues against the existing "critical size" paradigm for cell size control in bacteria and yeast.

The mathematical modelling of biomethane production and the growth of methanogenic bacteria in batch reactor systems fed with organic municipal solid waste  

Science Journals Connector (OSTI)

A mathematical model was developed and validated for an anaerobic digestion system of the Organic Fraction of Municipal Solid Wastes (OFMSWs) by using a laboratory-scale system of two Packed Bed Reactors (PBRs). The equations were obtained by the mass balances of methanogenic bacteria of affluent and effluent lixiviated, as well as the interior in each reactor. The methane rate was obtained by multiplying the methanogenic activity. A differential equation was fitted with experimental results to obtain the parameters that best describe methanogenic behaviour. These kinetic parameters were used with the modified logistic equation with the special case n = 1.

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 magic ratio'' 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 were 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.

Bacterial stress response to environmental radiation relating to the Fukushima radiation discharge event, Japan: Will environmental bacteria alter their antibiotic susceptibility profile?  

Science Journals Connector (OSTI)

Antibiotic resistance in clinical pathogens in humans may be traced back to resistance mechanisms in environmental bacteria and any factors, which are likely to alter (upregulate) resistance in environmental organisms, is of potential and eventual consequence to human pathogens. Furthermore, sublethal doses of gamma radiation to environmental organisms may cause sublethal stress and a selective pressure, which may lead to mutational events that alter the bacterium's susceptibility profile. A gamma (?) radiation simulation experiment was performed to emulate the exposure of four environmental bacteria, including Listeria innocua, Bacillus subtilis, E. coli and Pseudomonas aeruginosa, to levels of radiation in and around Fukushima, Japan, equating to 1, 10 and 100 years equivalence exposure. Alteration to susceptibility to 14 antibiotics was measured as the primary endpoint. There was no significant alteration in the susceptibility of the Gram-positive organisms, whereas both Gram-negative organisms became slightly more susceptible to the antibiotics tested over time. These data indicate that such radiation exposure will not increase the antibiotic resistance profile of these organisms and hence not add to the global public health burden of increased antibiotic resistance in human bacterial pathogens.

Chromium(VI) bioremoval by pseudomonas bacteria: role of microbial exudates for natural attenuation and biotreatment of Cr(VI) contamination  

SciTech Connect

Laboratory batch and column experiments were conducted to investigate the role of microbial exudates, e.g., exopolymeric substance (EPS) and alginic acid, on microbial Cr(VI) reduction by two different Pseudomonas strains (P. putida P18 and P. aeuroginosa P16) as a method for treating subsurface environment contaminated with Cr(VI). Our results indicate that microbial exudates significantly enhanced microbial Cr(VI) reduction rates by forming less toxic and highly soluble organo-Cr(III) complexes despite the fact Cr(III) has a very low solubility under the experimental conditions studied (e.g., pH 7). The formation of soluble organo-Cr(III) complexes led to the protection of the cells and chromate reductases from inactivation. In systems with no organic ligands, soluble organo-Cr(III) end products were formed between Cr(III) and the EPS directly released by bacteria due to cell lysis. Our results also provide evidence that cell lysis played an important role in microbial Cr(VI) reduction by Pseudomonas bacteria due to the release of constitutive reductases that intracellularly and/or extracellularly catalyzed the reduction of Cr(VI) to Cr(III). The overall results highlight the need for incorporation of the release and formation of organo-Cr(III) complexes into reactive transport models to more accurately design and monitor in situ microbial remediation techniques for the treatment of subsurface systems contaminated with Cr(VI).

MODELS FOR METAL-POOR STARS WITH ENHANCED ABUNDANCES OF C, N, O, Ne, Na, Mg, Si, S, Ca, AND Ti, IN TURN, AT CONSTANT HELIUM AND IRON ABUNDANCES  

SciTech Connect

Recent work has shown that most globular clusters have at least two chemically distinct components, as well as cluster-to-cluster differences in the mean [O/Fe], [Mg/Fe], and [Si/Fe] ratios at similar [Fe/H] values. In order to investigate the implications of variations in the abundances of these and other metals for H-R diagrams and predicted ages, grids of evolutionary sequences have been computed for scaled solar and enhanced {alpha}-element metal abundances, and for mixtures in which the assumed [m/Fe] value for each of the metals C, N, O, Ne, Na, Mg, Si, S, Ca, and Ti has been increased, in turn, by 0.4 dex at constant [Fe/H]. These tracks, together with isochrones for ages from Almost-Equal-To 5 to 14 Gyr, have been computed for -3.0 {<=} [Fe/H] {<=}-0.6, with helium abundances Y = 0.25, 0.29, and 0.33 at each [Fe/H] value, using upgraded versions of the Victoria stellar structure program and the Regina interpolation code, respectively. Turnoff luminosity versus age relations from isochrones are found to depend almost entirely on the importance of the CNO cycle, and thereby mainly on the abundance of oxygen. Since C, N, and O, as well as Ne and S, do not contribute significantly to the opacities at low temperatures and densities, variations in their abundances do not impact the predicted T{sub eff} scale of red giants. The latter is a strong function of the abundances of only Mg and Si (and Fe, possibly to a lesser extent) because they are so abundant and because they are strong sources of opacity at low temperatures. For these reasons, Mg and Si also have important effects on the temperatures of main-sequence stars. Due to their low abundances, Na, Ca, and Ti are of little consequence for stellar models. The effects of varying the adopted solar metals mixture and the helium abundance at a fixed [Fe/H] are also briefly discussed.

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

SciTech Connect

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.

Assessment of ocean waste disposal. Task 5. Human-health impacts of waste constituents. 2. Pathogens and antibiotic- and heavy-metal-resistant bacteria. Final report  

SciTech Connect

Disposal of wastes in the ocean has been practiced by coastal nations for many decades. All areas of the ocean have been subject to disposal use, including estuaries, nearshore, open shelf, and deep ocean sites. Until recently, it was believed that pathogenic bacteria did not survive for any significant period of time in estuarine and marine environments. Scientists and public-health workers never bothered to ask the question could viable, virulent pathogens be present in water samples even though they could not be detected by conventional plating methods. This laboratory answered this question in the affirmative for several bacterial pathogens, and this is discussed in detail. What follows in the report is a description of potentially harmful constituents of wastes, ways in which those constituents could reach humans, known incidents of human disease contracted from wastes, detection of waste-borne disease agents, management technologies, and monitoring and predictive technologies. Since the report is not just a review of the literature, not all known literature has been discussed. However, every attempt is made to include very relevant material, regardless of its age. What follows then is both a literature review and a position paper.

Sulfur accumulation in pinewood (Pinus sylvestris) induced by bacteria in a simulated seabed environment: Implications for marine archaeological wood and fossil fuels  

Science Journals Connector (OSTI)

Fresh pinewood blocks were submerged in sulfate and iron(II) containing media, inoculated with bacterial consortia isolated from seawater, aiming to simulate the seabed conditions of the Vasa shipwreck (1628). The consortia contained erosion (EB) and sulfate-reducing bacteria (SRB). Sulfur K-edge X-ray absorption near edge structure (XANES) spectroscopy and scanning X-ray spectromicroscopy images showed that organic sulfur, mainly thiols (R-SH), had accumulated in the lignin-rich middle lamella in EB-degraded parts of the wood. The sulfur content in the wood increased more than 10 times in 2 years. In another series with active inoculums from marine archaeological wood, the sulfur XANES spectra showed, after 4 years of anaerobic treatment, considerable amounts also of inorganic iron sulfides, Fe1?xS, which oxidized at atmospheric exposure. A sediment sample from the Vasa's seabed was also rich in iron sulfides, including pyrite, FeS2. X-ray fluorescence mappings of sulfur and phosphorous distributions indicate that scavenging SRB penetration, producing hydrogen sulfide in situ, is restricted to EB-degraded parts of the wood structure. The sulfur isotope depletion of 34S from ?34S = 21‰ in marine sulfate to ?34S = 6‰ and 1.8‰ for fractions of reduced sulfur and sulfate separated from a Vasa wood sample, respectively, suggests bacterial transformation. A fuller understanding of the routes of sulfur accumulation, as reactive iron sulfides and as organic sulfur, has important implications for improving conservation methods of marine archaeological wood. Moreover, the biogenic accumulation of organically bound sulfur, specifically in lignin-rich parts of waterlogged wood, has wider geochemical significance for fossil fuels of marine origin, as lignin-rich humic matter is important for the diagenetic formation of kerogens from anoxic marine sediments.
