Anaerobic Digestion Basics Anaerobic Digestion Basics Anaerobic Digestion Basics August 14, 2013 - 1:07pm Addthis Anaerobic digestion is a common technology in today's agriculture, municipal waste, and brewing industries. It uses bacteria to break down waste organic materials into methane and other gases, which can be used to produce electricity or heat. Methane and Anaerobic Bacteria Methane is a gas that contains molecules of methane with one atom of carbon and four atoms of hydrogen (CH4). It is the major component of the natural gas used in many homes for cooking and heating. It is odorless, colorless, and yields about 1,000 British thermal units (Btu) [252 kilocalories (kcal)] of heat energy per cubic foot (0.028 cubic meters) when burned. Natural gas is a fossil fuel that was created eons ago by the anaerobic

Photoenhanced anaerobic digestion of organic acids  

DOE Patents (OSTI)

A process is described for rapid conversion of organic acids and alcohols anaerobic digesters into hydrogen and carbon dioxide, the optimal precursor substrates for production of methane. The process includes addition of photosynthetic bacteria to the digester and exposure of the bacteria to radiant energy (e.g., solar energy). The process also increases the pH stability of the digester to prevent failure of the digester. Preferred substrates for photosynthetic bacteria are the organic acid and alcohol waste products of fermentative bacteria. In mixed culture with methanogenic bacteria or in defined co-culture with non-aceticlastic methanogenic bacteria, photosynthetic bacteria are capable of facilitating the conversion or organic acids and alcohols into methane with low levels of light energy input.

Halophytic microalgae as a feedstock for anaerobic digestion  

Science Journals Connector (OSTI)

Abstract Anaerobic digestion can be employed to produce methane biogas from residual microalgae biomass derived from either a lipid based biofuel process or wastewater treatment. There is interest in using halophytic microalgae for biofuel production due to their potential robustness in large-scale open pond production. The anaerobic digestion of halophytic microalgae biomass would however be challenging due to the high salinities not typically experienced in anaerobic digestion scenarios. Halophytic microalgae biomass as a potential substrate feedstock for anaerobic digestion would have salinities in excess of 3.5%, which is typically found in marine environments. To investigate the anaerobic digestion of halophytic microalgae issue the first stage of the reported study focuses on the changes undertaken in the bacterial community associated with the anaerobic digestion of piggery effluent under increasing saline conditions, with the aim of establishing a saline tolerant anaerobic digestion inoculum capable of digesting feedstocks under high salinity conditions. Favourable results from this inoculum development study allowed the investigation of anaerobic digestion of halophytic microalgae. The reported results demonstrate that a saline tolerant inoculum was maintained. Subsequent denaturing gradient gel electrophoresis (DGGE) fingerprinting of the resulting halophytic bacterial community showed several halophytic methanogens. The inoculum was used to digest the halophytic microalgae. The resulting gas data showed that biogas production of 358 ± 53 mL/g of volatile solids (VS) with a methane content of 54 ± 4.3% methane was achieved at 7% salinity. The volume of biogas produced on a wet weight microalgae biomass basis was 122 ± 26 and 175 ± 25 mL/g of halophytic microalgae biomass respectively (74 ± 2.8 wt.% moisture content). The conversion of carbon in the feedstock to methane achieved an efficiency of 26.4% and 46.6% at 3.4% and 7% salinity respectively. A halo-tolerant anaerobic digestion microbial community could be further optimized to complete the loop with nutrient recycle required with the production of halophytic microalgae based biofuels and potentially, hypersaline wastewater treatment applications.

Anaerobic batch co-digestion of Spartina alterniflora and potato  

Science Journals Connector (OSTI)

The potential of mesophilic anaerobic batch digestion for the treatment of Spartina alterniflora, an invasive species widely distributed along Chinese coastlines, through co-digestion with readily biodegradable organics has been assessed. The accumulative biogas yield from S. alterniflora alone was 251 ml/g Total Solid (TS) (at 35°C), at TS of 6%, co-digestion with 80% of S. alterniflora and 20% of potato representing 6% of TS, gave a biogas yield of 383 ml/g TS (at 35°C). This is an increase of 52.5% compared with that obtained from digestion of pure S. alterniflora. In conclusion, using readily biodegradable potato as co-substrate of S. alterniflora can increase its anaerobic digestibility and biogas yield.

Anaerobic Digestion of Food Waste?recycling Wastewater  

Science Journals Connector (OSTI)

Food waste?recycling (FWR) wastewater was evaluated as feedstock for two?stage anaerobic digestion at different hydraulic retention times (HRTs). The FWR wastewater tested contained high concentrations of organic materials and had chemical oxygen demand (COD) >130 g/L and volatile solids (VS) >55 g/L. Two identical two?stage anaerobic digesters were operated to investigate the performance at six HRTs ranging from 10–25 days. In the acidogenic reactor the total carbohydrate reduction efficiency and volatile fatty acid production dramatically decreased when acidogenic HRT was wastewater as feedstock.

Biomethane production by anaerobic digestion of organic waste  

Science Journals Connector (OSTI)

Abstract Anaerobic Digestion (AD) is a biological process that takes place naturally when bacteria break down organic matter in environments with or without oxygen. Controlled anaerobic digestion of organic waste in enclosed landfill will generate methane. Almost any organic material can be processed with AD, including waste paper and cardboard (of a grade that is too low to recycle because of food contamination), grass clippings, leftover food, industrial effluents, sewage and animal waste. AD produces biogas which is comprised of around 60% methane (CH4) and 40% carbon dioxide (CO2). This biogas can be used to generate heat or electricity and/or can be used as a vehicular fuel. If the intended use is for power generation the biogas must be scrubbed to remove a number of impurities. After conditioning the biogas can be used for onsite power generation, to heat homes or can be added to the national natural gas grid. In recent years several research groups have shown the possibility of upgrading the biogas for biomethane production [1]. This study will show the feasibility of integrating anaerobic digestion plant with onsite polymeric membrane purification system for conditioned biomethane production.

Optimization of solid state anaerobic digestion of the OFMSW by digestate recirculation: A new approach  

Science Journals Connector (OSTI)

Abstract Dry anaerobic digestion (AD) of OFMSW was optimized in order to produce biogas avoiding the use of solid inoculum. Doing so the dry AD was performed irrigating the solid waste with liquid digestate (flow rate of 1:1.18–1:0.9 w/w waste/digestate; 21 d of hydraulic retention time – HRT) in order to remove fermentation products inhibiting AD process. Results indicated that a high hydrolysis rate of organic matter (OM) and partial biogas production were obtained directly during the dry AD. Hydrolysate OM was removed from digester by the percolate flow and it was subsequently used to feed a liquid anaerobic digester. During dry AD a total loss of 36.9% of total solids was recorded. Methane balance indicated that 18.4% of potential methane can be produced during dry AD and 49.7% by the percolate. Nevertheless results obtained for liquid AD digestion indicated that only 20.4% and 25.7% of potential producible methane was generated by adopting 15 and 20 days of HRT, probably due to the AD inhibition due to high presence of toxic ammonia forms in the liquid medium.

Application of dried anaerobic digested sewage sludge as phenol biosorbent  

Science Journals Connector (OSTI)

Untreated anaerobically digested sewage sludge was used for the first time as a biosorbent for removing phenol from aqueous solution. Results showed that adsorption capacity was influenced by the pH of the aqueous solution with an observed maximum phenol removal at pH around 6-8. The adsorption equilibrium of phenolic compounds was obtained after almost two hours with an adsorption of approximately 90% of the phenolic compounds. A sorbent concentration of 1.8 g/L was found to insure the best removal percentage and the best sorbent capacity. Both Langmuir and Freundlich models have provided reasonable fittings for the data of phenol adsorption. The experimental data fitted the pseudo-second-order kinetic model and the intraparticle diffusion model. The values of change in Gibbs free energy (?G°), enthalpy (?H°) and entropy (?S°) were calculated. The thermodynamic study of adsorption process showed that the process was exothermic in nature.

Anaerobic digestion of glycerol and co-digestion of glycerol and pig manure  

Science Journals Connector (OSTI)

The potential of glycerol obtained from transesterification of waste cooking oil as a main carbon source for biogas production was investigated. The glycerol was highly contaminated with oils and fats and was pretreated with sulfuric acid. Using a carbon source of glucose as a control, we compared biogas production from the acid-treated glycerol in a synthetic medium and the acid-treated glycerol mixed with pig manure. The anaerobic digestion of acid-treated glycerol with supplement in a synthetic medium was found to be satisfactory at organic loading rates (OLR) between 1.3, 1.6 and 2.6 g chemical oxygen demand (COD) L?1 d?1. The maximum methane yield of 0.32 L at Standard temperature and pressure (STP) g?1 COD removal was achieved at an OLR of 1.6 g COD L?1 d?1 and the methane content was 54% on an average. At a higher organic loading rate of 5.4 g COD L?1 d?1, the propionic acid to acetic acid ratio was higher than the critical threshold limit for metabolic imbalance. Anaerobic digestion of acid-treated glycerol with pig manure was also investigated at the COD ratio of 80:20 (glycerol:pig manure). The anaerobic digestion of acid-treated glycerol with pig manure was found to be satisfactory at organic loading rates between 1.3, 1.7, 2.9 and 5.0 g COD L?1 d?1 in terms of COD reduction (>80%) and methane content of (62% on an average). However, the biogas production rate was found to significantly decrease at the highest load. The maximum methane yield of 0.24 L STP g?1 COD removal was achieved at an OLR of 1.3 g COD L?1 d?1.

Anaerobic Digestion and Combined Heat and Power Study  

SciTech Connect

One of the underlying objectives of this study is to recover the untapped energy in wastewater biomass. Some national statistics worth considering include: (1) 5% of the electrical energy demand in the US is used to treat municipal wastewater; (2) This carbon rich wastewater is an untapped energy resource; (3) Only 10% of wastewater treatment plants (>5mgd) recover energy; (4) Wastewater treatment plants have the potential to produce > 575 MW of energy nationwide; and (5) Wastewater treatment plants have the potential to capture an additional 175 MW of energy from waste Fats, Oils and Grease. The WSSC conducted this study to determine the feasibility of utilizing anaerobic digestion and combined heat and power (AD/CHP) and/or biosolids gasification and drying facilities to produce and utilize renewable digester biogas. Digester gas is considered a renewable energy source and can be used in place of fossil fuels to reduce greenhouse gas emissions. The project focus includes: (1) Converting wastewater Biomass to Electricity; (2) Using innovative technologies to Maximize Energy Recovery; and (3) Enhancing the Environment by reducing nutrient load to waterways (Chesapeake Bay), Sanitary Sewer Overflows (by reducing FOG in sewers) and Greenhouse Gas Emissions. The study consisted of these four tasks: (1) Technology screening and alternative shortlisting, answering the question 'what are the most viable and cost effective technical approaches by which to recover and reuse energy from biosolids while reducing disposal volume?'; (2) Energy recovery and disposal reduction potential verification, answering the question 'how much energy can be recovered from biosolids?'; (3) Economic environmental and community benefit analysis, answering the question 'what are the potential economic, environmental and community benefits/impacts of each approach?'; and (4) Recommend the best plan and develop a concept design.

Anaerobic digestion of wool scouring wastewater in a digester operated semi-continuously for biomass retention  

Science Journals Connector (OSTI)

An anaerobic digester, operated semi-continuously in order to retain high concentrations of biomass in the digester, was used to treat wool scouring wastewater. At a space load of 9·9 kg COD m?3 day ?1 (hydraulic retention time, 2·8 days) >56% of the COD and >47% of the grease were removed. At these efficiencies, this rate was estimated to be at least 2·5·3· times greater than that which would be achieved in a continuously stirred digester. Preliminary studies of enzymatic pretreatment of the scouring effluent showed that significantly improved treatment rates and/or efficiencies could be achieved—i.e. >70% removal of both the COD and grease at a space load of 12 kg COD m?3 day?1. It is unlikely that any substancial levels of flocculation would develop in this system and it is expected that the moderate use of polyelectrolytes would be required to help maintain the VSS concentration in the reactor.

Nitrification of centrate from dewatering of anaerobically digested sludge  

Science Journals Connector (OSTI)

Nitrification of anaerobically digested sludge centrate was studied in bench-scale suspended growth and fixed film enhanced suspended growth systems at temperatures of 10.5-28.5°C and pH values of 6.0-9.1. Nitrification followed zero-order kinetics in both systems, and ammonia removals in excess of 99% were observed. The temperature dependency of the suspended growth nitrification rate observed under not fully acclimated biomass conditions at pH between 6.8 and 8.5, was expressed as kT = k20?T-20where k20 and ? were found to be 0.34 mg NH3-N/MLVSS-d and 1.033, respectively. The nitrification rate in the fixed film enhanced suspended growth system involving styrofoam pads ranged from 0.11 to 0.13 mg NH3-N/mg MLVSS-d at temperatures of 21.5-25°C and pH values of 7.8-8.6. The process contained suspended solids in the range of 10-20 mg/l.

Comparison of different liquid anaerobic digestion effluents as inocula and nitrogen sources for solid-state batch anaerobic digestion of corn stover  

SciTech Connect

Highlights: Black-Right-Pointing-Pointer Compared methane production of solid AD inoculated with different effluents. Black-Right-Pointing-Pointer Food waste effluent (FWE) had the largest population of acetoclastic methanogens. Black-Right-Pointing-Pointer Solid AD inoculated with FWE produced the highest methane yield at F/E ratio of 4. Black-Right-Pointing-Pointer Dairy waste effluent (DWE) was rich of cellulolytic and xylanolytic bacteria. Black-Right-Pointing-Pointer Solid AD inoculated with DWE produced the highest methane yield at F/E ratio of 2. - Abstract: Effluents from three liquid anaerobic digesters, fed with municipal sewage sludge, food waste, or dairy waste, were evaluated as inocula and nitrogen sources for solid-state batch anaerobic digestion of corn stover in mesophilic reactors. Three feedstock-to-effluent (F/E) ratios (i.e., 2, 4, and 6) were tested for each effluent. At an F/E ratio of 2, the reactor inoculated by dairy waste effluent achieved the highest methane yield of 238.5 L/kgVS{sub feed}, while at an F/E ratio of 4, the reactor inoculated by food waste effluent achieved the highest methane yield of 199.6 L/kgVS{sub feed}. The microbial population and chemical composition of the three effluents were substantially different. Food waste effluent had the largest population of acetoclastic methanogens, while dairy waste effluent had the largest populations of cellulolytic and xylanolytic bacteria. Dairy waste also had the highest C/N ratio of 8.5 and the highest alkalinity of 19.3 g CaCO{sub 3}/kg. The performance of solid-state batch anaerobic digestion reactors was closely related to the microbial status in the liquid anaerobic digestion effluents.

Intermediate-scale high-solids anaerobic digestion system operational development  

SciTech Connect

Anaerobic bioconversion of solid organic wastes represents a disposal option in which two useful products may be produced, including a medium Btu fuel gas (biogas) and a compost-quality organic residue. The application of high-solids technology may offer several advantages over conventional low-solids digester technology. Operation of the anaerobic digestion process at high solids reduces the level of process water and thereby the size and capital costs for the digester system. In addition, by virtue of the lack of available water, the microbial catalysts are more productive in feedstock polymer hydrolysis. The National Renewable Energy Laboratory (NREL) has developed a unique digester system capable of uniformly mixing high-solids materials at low cost. Information gained from laboratory-scale digester research was used to develop die intermediate-scale digester system. This system represents a 50-fold scale-up of the original digester system and includes continuous feed addition and computer monitoring and control. During the first 1.15 years of operation, a variety of modifications and improvements were instituted to increase the safety, reliability, and performance of the system. Those improvements -- which may be critical in further scale-up efforts using the NREL high-solids digester design -- are detailed in this report.

A systemic approach for dimensioning and designing anaerobic bio-digestion/energy generation biomass supply networks  

Science Journals Connector (OSTI)

Abstract Anaerobic bio-digestion/energy generation complexes using animal waste raw materials represent an important component of renewable energy initiatives and policies worldwide, and are significant contributors to broaden sustainability efforts. In such projects bio-power feasibility depends heavily on generation complex access to biomass which is of costly transportation. As a result, an important component of renewable energy planning is the optimization of a logistics system to guarantee low-cost access to animal waste. This access is a function of local characteristics including number and geographic location of organic waste sources, operating and maintenance costs of the generation facility, energy prices, and marginal contribution of biomass collected and delivered to the anaerobic bio-digestion unit. Because biomass exhibits high transportation costs per unit of energy ultimately generated, and because different types of biomass have different biogas-generating properties, design of the supply logistics system can be the determinant factor towards economic viability of energy generation from an anaerobic bio-digestion plant. Indeed, to address this problem it is helpful to consider the farms, the logistics system, the anaerobic bio-digestion plant, and the generation plant as subsystems in an integrated system. Additionally, the existence of an outlet for manure may allow farmers to significantly raise boundaries of one constraint they face, namely disposing of animal waste, therefore permitting increases in farm production capacity. This paper suggests and outlines a systematic methodology to address the design of such systems.

Citrus essential oils and their influence on the anaerobic digestion process: An overview  

Science Journals Connector (OSTI)

Abstract Citrus waste accounts for more than half of the whole fruit when processed for juice extraction. Among valorisation possibilities, anaerobic digestion for methane generation appears to be the most technically feasible and environmentally friendly alternative. However, citrus essential oils can inhibit this biological process. In this paper, the characteristics of citrus essential oils, as well as the mechanisms of their antimicrobial effects and potential adaptation mechanisms are reviewed. Previous studies of anaerobic digestion of citrus waste under different conditions are presented; however, some controversy exists regarding the limiting dosage of limonene for a stable process (24–192 mg of citrus essential oil per liter of digester and day). Successful strategies to avoid process inhibition by citrus essential oils are based either on recovery or removal of the limonene, by extraction or fungal pre-treatment respectively.

Various types of insulating composite materials were used on ceramic digesters for the control of temperature. Maintenance of temperature is highlighted in this paper. The above types of digesters can adequately control the temperature, especially in the winter season. The results of extensive experimental and theoretical studies have been cited in this paper. This work is beneficial for those plants which are generally in higher altitude stations with low atmospheric temperature, like Leh (India). These types of digesters were found to be very useful for the production of biogas, especially from aquatic biomass like water hyacinth.

A network design model for biomass to energy supply chains with anaerobic digestion systems  

Science Journals Connector (OSTI)

Abstract Development and implementation of renewable energy systems, as a part of the solution to the worldwide increasing energy consumption, have been considered as emerging areas to offer an alternative to the traditional energy systems with limited fossil fuel resources and to challenge environmental problems caused by them. Biomass is one of the alternative energy resources and agricultural, animal and industrial organic wastes can be treated as biomass feedstock in biomass to energy conversion systems. This study aims to develop an effective supply chain network design model for the production of biogas through anaerobic digestion of biomass. In this regard, a mixed integer linear programming model is developed to determine the most appropriate locations for the biogas plants and biomass storages. Besides the strategic decisions such as determining the numbers, capacities and locations of biogas plants and biomass storages, the biomass supply and product distribution decisions can also be made by this model. Mainly, waste biomass is considered as feedstock to be digested in anaerobic digestion facilities. To explore the viability of the proposed model, computational experiments are performed on a real-world problem. Additionally, a sensitivity analysis is performed to account for the uncertainties in the input data to the decision problem.

Temporal variation in methanogen communities of four different full-scale anaerobic digesters treating food waste-recycling wastewater  

Science Journals Connector (OSTI)

Abstract Methanogen communities were investigated using 454 pyrosequencing in four different full-scale anaerobic digesters treating food waste-recycling wastewater. Seasonal samples were collected for 2 years, and 24 samples were available for microbial analysis from a plug flow thermophilic (PT) digester, a continuously-stirred tank thermophilic (CT) digester, an upflow anerobic sludge blanket mesophilic (UM) digester, and a continuously-stirred tank mesophilic (CM) digester. Methanoculleus, Methanobacterium, Methanothermobacter, and Methanosaeta were revealed to be key methanogens in full-scale anaerobic digestion process treating food waste-recycling wastewater. In the PT digester, Methanoculleus was dominant (96.8%). In the CT digester, Methanoculleus was dominant (95.4%) during the first year of operation, but the dominant genus was shifted to Methanothermobacter (98.5%) due to pH increase. In the UM digester, Methanosaeta was dominant (87.2%). In the CM digester, Methanoculleus was constantly dominant (74.8%) except during CM5 when Methanosaeta was dominant (62.6%) due to the low residual acetate concentration (0.1 g/L).

Flux analysis of the human proximal colon using anaerobic digestion model 1  

Science Journals Connector (OSTI)

Abstract The colon can be regarded as an anaerobic digestive compartment within the gastro intestinal tract (GIT). An in silico model simulating the fluxes in the human proximal colon was developed on basis of the anaerobic digestion model 1 (ADM1), which is traditionally used to model waste conversion to biogas. Model calibration was conducted using data from in vitro fermentation of the proximal colon (TIM-2), and, amongst others, supplemented with the bio kinetics of prebiotic galactooligosaccharides (GOS) fermentation. The impact of water and solutes absorption by the host was also included. Hydrolysis constants of carbohydrates and proteins were estimated based on total short chain fatty acids (SCFA) and ammonia production in vitro. Model validation was established using an independent dataset of a different in vitro model: an in vitro three-stage continuous culture system. The in silico model was shown to provide quantitative insight in the microbial community structure in terms of functional groups, and the substrate and product fluxes between these groups as well as the host, as a function of the substrate composition, pH and the solids residence time (SRT). The model confirms the experimental observation that methanogens are washed out at low pH or low SRT-values. The in silico model is proposed as useful tool in the design of experimental setups for in vitro experiments by giving insight in fermentation processes in the proximal human colon.

Nitrogen availability and indirect measurements of greenhouse gas emissions from aerobic and anaerobic biowaste digestates applied to agricultural soils  

SciTech Connect

Highlights: • Nitrogen release in digestate-amended soil depends on the digestate type. • Overall N release is modulated by digestate mineral and mineralisable N contents. • Microbial immobilisation does not influence overall release of digestate N in soil. • Digestate physical properties and soil type interact to affect overall N recovery. • High labile C inputs in digestate may promote denitrification in fine-textured soil. - Abstract: Recycling biowaste digestates on agricultural land diverts biodegradable waste from landfill disposal and represents a sustainable source of nutrients and organic matter (OM) to improve soil for crop production. However, the dynamics of nitrogen (N) release from these organic N sources must be determined to optimise their fertiliser value and management. This laboratory incubation experiment examined the effects of digestate type (aerobic and anaerobic), waste type (industrial, agricultural and municipal solid waste or sewage sludge) and soil type (sandy loam, sandy silt loam and silty clay) on N availability in digestate-amended soils and also quantified the extent and significance of the immobilisation of N within the soil microbial biomass, as a possible regulatory mechanism of N release. The digestate types examined included: dewatered, anaerobically digested biosolids (DMAD); dewatered, anaerobic mesophilic digestate from the organic fraction of municipal solid waste (DMADMSW); liquid, anaerobic co-digestate of food and animal slurry (LcoMAD) and liquid, thermophilic aerobic digestate of food waste (LTAD). Ammonium chloride (NH{sub 4}Cl) was included as a reference treatment for mineral N. After 48 days, the final, maximum net recoveries of mineral N relative to the total N (TN) addition in the different digestates and unamended control treatments were in the decreasing order: LcoMAD, 68%; LTAD, 37%, DMAD, 20%; and DMADMSW, 11%. A transient increase in microbial biomass N (MBN) was observed with LTAD application, indicating greater microbial activity in amended soil and reflecting the lower stability of this OM source, compared to the other, anaerobic digestate types, which showed no consistent effects on MBN compared to the control. Thus, the overall net release of digestate N in different soil types was not regulated by N transfer into the soil microbial biomass, but was determined primarily by digestate properties and the capacity of the soil type to process and turnover digestate N. In contrast to the sandy soil types, where nitrate (NO{sub 3}{sup -}) concentrations increased during incubation, there was an absence of NO{sub 3}{sup -} accumulation in the silty clay soil amended with LTAD and DMADMSW. This provided indirect evidence for denitrification activity and the gaseous loss of N, and the associated increased risk of greenhouse gas emissions under certain conditions of labile C supply and/or digestate physical structure in fine-textured soil types. The significance and influence of the interaction between soil type and digestate stability and physical properties on denitrification processes in digestate-amended soils require urgent investigation to ensure management practices are appropriate to minimise greenhouse gas emissions from land applied biowastes.

A model of anaerobic digestion for biogas production using Abel equations

We consider a nonlinear mathematical model for the study of anaerobic digestion processes. We decompose the original system of nonlinear ordinary differential equations into subsystems. For these subsystems we prove existence of lower and upper solutions in reverse order for one of the va\\-ria\\-bles. The upper and lower solutions are constructed in analytical form. Furthermore, the upper solutions of subsystem for feeding bacteria are related with solutions of Abel equations of the first kind. Using numerical and theoretical arguments we examine how to obtain upper and lower solutions approximated to the numerical solution of the system. In this work we establish special techniques of lower-upper solution, which includes reverse order for non monotone systems, in contrast to the techniques used by H.L. Smith and P. Waltman on their monograph.

Influence of bed materials on methanogenic characteristics and immobilized microbes in anaerobic digester  

Science Journals Connector (OSTI)

This paper reports and discusses the effects of bed materials on the performance of methanogenic fluidized bed reactors with acetic acid as the sole organic substrate. Four bed materials (carbon filter, rock wool, loofah sponge and polyurethane foam) were evaluated and compared for their methanogenic characteristics and immobilized microbes. The present results indicated that the characteristics of the bed materials for immobilization had a significant influence on the methane production. The loofah sponge and polyurethane foam were suggested to be suitable for the bed material in anaerobic digestion. The best methane yield was obtained from the loofah reactor among the four kinds of bed materials. The main cellular morphologies present in the biofilms of the four different materials on the colonization were observed using scanning electron microscopy. The microphotographs indicated that the biofilm was primarily composed of coccus, diplococci-shaped Methanosarcina-like cells, long rods of Methanobacterium and coccobacillus of Methanobrevibacter-like bacteria. The morphologies observed from the microscopic analysis indicated that the different bed materials could provide specific conditions for the adherence of distinct microorganism types. Furthermore, a 16S rRNA phylogenetic analysis was conducted to compare the immobilized archaeal population. The results of the 16S rRNA phylogenetic analysis indicated that the major immobilized methanogens were Methanobacterium formicicum, Methanosarcina barkeri and Methanosarcina mazei in all the bed materials. A similar clone distribution was observed with the loofah sponge and the carbon felt.

Microbial community structures were assessed in a two-stage anaerobic digestion system treating food waste-recycling wastewater. The reactors were operated for 390 d at 10 different hydraulic retention times (HRTs) ranging from 25 to 4 d. Stable operation was achieved with the overall chemical oxygen demand (COD) removal efficiency of 73.0–85.9% at organic loading rate of up to 35.6 g COD/L·d. Performance of the acidogenic reactors, however, changed significantly during operation. This change coincided with transition of the bacterial community from one dominated by Aeriscardovia- and Lactobacillus amylovorus-related species to one dominated by Lactobacillus acetotolerans- and Lactobacillus kefiri-like organisms. In methanogenic reactors, the microbial community structures also changed at this stage along with the shift from Methanoculleus- to Methanosarcina-like organisms. This trend was confirmed by the non-metric multidimensional scaling joint plot of microbial shifts along with performance parameters. These results indicated that the overall process performance was relatively stable compared to the dynamic changes in the microbial structures and the acidogenic performance.

Thermophilic anaerobic digestion of thermal pretreated sludge: Role of microbial community structure and correlation with process performances  

Science Journals Connector (OSTI)

Abstract Thermal hydrolysis pretreatment coupled with Thermophilic Anaerobic Digestion (TAD) for Waste Activated Sludge (WAS) treatment is a promising combination to improve biodegradation kinetics during stabilization. However, to date there is a limited knowledge of the anaerobic biomass composition and its impact on TAD process performances. In this study, the structure and dynamics of the microbial communities selected in two semi-continuous anaerobic digesters, fed with untreated and thermal pretreated sludge, were investigated. The systems were operated for 250 days at different organic loading rate. 16S rRNA gene clonal analysis and Fluorescence In Situ Hybridization (FISH) analyses allowed us to identify the majority of bacterial and archaeal populations. Proteolytic Coprothermobacter spp. and hydrogenotrophic Methanothermobacter spp. living in strict syntrophic association were found to dominate in TAD process. The establishment of a syntrophic proteolytic pathway was favoured by the high temperature of the process and enhanced by the thermal pretreatment of the feeding sludge. Proteolytic activity, alone or with thermal pretreatment, occurred during TAD as proven by increasing concentration of soluble ammonia and soluble COD (sCOD) during the process. However, the availability of a readily biodegradable substrate due to pretreatment allowed to significant sCOD removals (more than 55%) corresponding to higher biogas production in the reactor fed with thermal pretreated sludge. Microbial population dynamics analysed by FISH showed that Coprothermobacter and Methanothermobacter immediately established a stable syntrophic association in the reactor fed with pretreated sludge in line with the overall improved TAD performances observed under these conditions.

Parameters affecting the stability of the digestate from a two-stage anaerobic process treating the organic fraction of municipal solid waste  

SciTech Connect

This paper focused on the factors affecting the respiration rate of the digestate taken from a continuous anaerobic two-stage process treating the organic fraction of municipal solid waste (OFMSW). The process involved a hydrolytic reactor (HR) that produced a leachate fed to a submerged anaerobic membrane bioreactor (SAMBR). It was found that a volatile solids (VS) removal in the range 40-75% and an operating temperature in the HR between 21 and 35 {sup o}C resulted in digestates with similar respiration rates, with all digestates requiring 17 days of aeration before satisfying the British Standard Institution stability threshold of 16 mg CO{sub 2} g VS{sup -1} day{sup -1}. Sanitization of the digestate at 65 {sup o}C for 7 days allowed a mature digestate to be obtained. At 4 g VS L{sup -1} d{sup -1} and Solid Retention Times (SRT) greater than 70 days, all the digestates emitted CO{sub 2} at a rate lower than 25 mg CO{sub 2} g VS{sup -1} d{sup -1} after 3 days of aeration, while at SRT lower than 20 days all the digestates displayed a respiration rate greater than 25 mg CO{sub 2} g VS{sup -1} d{sup -1}. The compliance criteria for Class I digestate set by the European Commission (EC) and British Standard Institution (BSI) could not be met because of nickel and chromium contamination, which was probably due to attrition of the stainless steel stirrer in the HR.

Pilot-scale anaerobic co-digestion of municipal biomass waste and waste activated sludge in China: Effect of organic loading rate  

SciTech Connect

Highlights: Black-Right-Pointing-Pointer Co-digestion of municipal biomass waste (MBW) and waste activated sludge (WAS) was examined on a pilot-scale reactor. Black-Right-Pointing-Pointer System performance and stability under OLR of 1.2, 2.4, 3.6, 4.8, 6.0 and 8.0 kg VS (m{sup 3} d){sup -1} were analyzed. Black-Right-Pointing-Pointer A maximum methane production rate of 2.94 m{sup 3} (m{sup 3} d){sup -1} was achieved at OLR of 8.0 kg VS (m{sup 3} d){sup -1} and HRT of 15d. Black-Right-Pointing-Pointer With the increasing OLRs, pH values, VS removal rate and methane concentration decreased and VFA increased. Black-Right-Pointing-Pointer The changing of biogas production rate can be a practical approach to monitor and control anaerobic digestion system. - Abstract: The effects of organic loading rate on the performance and stability of anaerobic co-digestion of municipal biomass waste (MBW) and waste activated sludge (WAS) were investigated on a pilot-scale reactor. The results showed that stable operation was achieved with organic loading rates (OLR) of 1.2-8.0 kg volatile solid (VS) (m{sup 3} d){sup -1}, with VS reduction rates of 61.7-69.9%, and volumetric biogas production of 0.89-5.28 m{sup 3} (m{sup 3} d){sup -1}. A maximum methane production rate of 2.94 m{sup 3} (m{sup 3} d){sup -1} was achieved at OLR of 8.0 kg VS (m{sup 3} d){sup -1} and hydraulic retention time of 15 days. With increasing OLRs, the anaerobic reactor showed a decrease in VS removal rate, average pH value and methane concentration, and a increase of volatile fatty acid concentration. By monitoring the biogas production rate (BPR), the anaerobic digestion system has a higher acidification risk under an OLR of 8.0 kg VS (m{sup 3} d){sup -1}. This result remarks the possibility of relating bioreactor performance with BPR in order to better understand and monitor anaerobic digestion process.

Micro-scale anaerobic digestion of point source components of organic fraction of municipal solid waste  

SciTech Connect

The fermentation characteristics of six specific types of the organic fraction of municipal solid waste (OFMSW) were examined, with an emphasis on properties that are needed when designing plug-flow type anaerobic bioreactors. More specifically, the decomposition patterns of a vegetable (cabbage), fruits (banana and citrus peels), fresh leaf litter of bamboo and teak leaves, and paper (newsprint) waste streams as feedstocks were studied. Individual OFMSW components were placed into nylon mesh bags and subjected to various fermentation periods (solids retention time, SRT) within the inlet of a functioning plug-flow biogas fermentor. These were removed at periodic intervals, and their composition was analyzed to monitor decomposition rates and changes in chemical composition. Components like cabbage waste, banana peels, and orange peels fermented rapidly both in a plug-flow biogas reactor (PFBR) as well as under a biological methane potential (BMP) assay, while other OFMSW components (leaf litter from bamboo and teak leaves and newsprint) fermented slowly with poor process stability and moderate biodegradation. For fruit and vegetable wastes (FVW), a rapid and efficient removal of pectins is the main cause of rapid disintegration of these feedstocks, which left behind very little compost forming residues (2-5%). Teak and bamboo leaves and newsprint decomposed only to 25-50% in 30 d. These results confirm the potential for volatile fatty acids accumulation in a PFBR's inlet and suggest a modification of the inlet zone or operation of a PFBR with the above feedstocks.

Modelling the energy performance of a farm-scale cellulose to ethanol process with on-site cellulase production and anaerobic digestion  

Science Journals Connector (OSTI)

Abstract A farm-scale process for converting wheat straw to ethanol was modelled to assess its energy performance. The process incorporates the on-site production of crude unprocessed liquid cellulase produced via solid-state fermentation, and the anaerobic digestion of process residues to supply heat and electricity. Results include energy yield ratios from 6 to 9, reductions of 80–90 % in the energy required to produce and transport the cellulase compared to commercial preparations, and a net surplus of on-site heat and electricity. From these improvements in process efficiency, environmental benefits follow.

Waste-to-wheel analysis of anaerobic-digestion-based renewable natural gas pathways with the GREET model.  

SciTech Connect

In 2009, manure management accounted for 2,356 Gg or 107 billion standard cubic ft of methane (CH{sub 4}) emissions in the United States, equivalent to 0.5% of U.S. natural gas (NG) consumption. Owing to the high global warming potential of methane, capturing and utilizing this methane source could reduce greenhouse gas (GHG) emissions. The extent of that reduction depends on several factors - most notably, how much of this manure-based methane can be captured, how much GHG is produced in the course of converting it to vehicular fuel, and how much GHG was produced by the fossil fuel it might displace. A life-cycle analysis was conducted to quantify these factors and, in so doing, assess the impact of converting methane from animal manure into renewable NG (RNG) and utilizing the gas in vehicles. Several manure-based RNG pathways were characterized in the GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation) model, and their fuel-cycle energy use and GHG emissions were compared to petroleum-based pathways as well as to conventional fossil NG pathways. Results show that despite increased total energy use, both fossil fuel use and GHG emissions decline for most RNG pathways as compared with fossil NG and petroleum. However, GHG emissions for RNG pathways are highly dependent on the specifics of the reference case, as well as on the process energy emissions and methane conversion factors assumed for the RNG pathways. The most critical factors are the share of flared controllable CH{sub 4} and the quantity of CH{sub 4} lost during NG extraction in the reference case, the magnitude of N{sub 2}O lost in the anaerobic digestion (AD) process and in AD residue, and the amount of carbon sequestered in AD residue. In many cases, data for these parameters are limited and uncertain. Therefore, more research is needed to gain a better understanding of the range and magnitude of environmental benefits from converting animal manure to RNG via AD.

The effect of algae species on biodiesel and biogas production observed by using a data model combines algae cultivation with an anaerobic digestion (ACAD) and a biodiesel process  

Science Journals Connector (OSTI)

Abstract The influence of an algae species based on the biodiesel yield was investigated by using a combined plant model from the literature. The model has six different processes: algal cultivation, the flocculation and separation process, biodiesel production, anaerobic digestion, scrubbing, and combined heat and power (CHP). The data model in the literature was operated with the values for Chlorella vulgaris. To investigate the roles of the algae species on the biodiesel yield in the model, two different algae species, Nannochloropsis sp. and Haematococcus pluvialis, were selected. Depending on the data from these algae in the literature, three different scenarios were modeled in the study. The model shows that all of the scenarios for biodiesel production can be totally independent of an external energy supply. Energy estimations for all of the applications scenarios show that the system produces more energy than the amount that is required for the processing operation.

Which is the preferable biogas utilisation technology for anaerobic digestion of agricultural crops in Ireland: Biogas to CHP or biomethane as a transport fuel?  

Science Journals Connector (OSTI)

The utilisation of anaerobic digestion to produce biogas as an energy source is a mature technology in many European countries but is yet to be developed in Ireland. In 2009, the EU issued the Renewable Energy Source Directive 2009/28/EC which requires a 20% share of renewable energy sources (heat and electricity) in final energy consumption for all member states, respectively, including a 10% share of biofuels in the transport sector by 2020. The introduction of biogas to produce power and electricity in the form of CHP technology and biomethane as a transport fuel can help Ireland achieve the mandatory targets set by the directive. The key focus of the paper is to determine the optimum small to medium scale biogas technology and the impact the introduction of that technology infrastructure will have on renewable energy targets for Ireland. In terms of feedstock, agricultural sources such as energy crops and slurry offer a sustainable input to the anaerobic digestion process. The crop rotations under consideration consist of different arrangements of grass silage, maize silage and barley. Grass silage is found to be the most suitable crop for biogas energy production while biogas upgrading to biomethane as a transport fuel has the optimum technology potential in Ireland. To fuel a car operating on biomethane, 0.22 ha of grass land is required annually. Full scale national development of 5% of the area under grass in Ireland will contribute 11.4% of renewable energy to the total final transport energy demand by 2020, surpassing the target set by the Renewable Energy Source Directive 2009/28/EC.

The Study of Two Stages Anaerobic Digestion Application and Suitable Bio-Film as an Effort to Improve Bio-Gas Productivity from Jatropha Curcas Linn Capsule Husk  

Science Journals Connector (OSTI)

Abstract The conversion program from kerosene to LPG in Indonesia has positive impact on saving budget of fuel subsidized. However, the program does not only depend on LPG supply from overseas but also inadvisable related to the LPG availability in the world. Bio-gas is renewable energy which categorized as modern cooking oil. This gaseous bio- fuel is feasible in Indonesia due to plenty of bio-gas resources such as bio-mass and waste, simple technology, supporting tropical climate on bio-gas process, no food competition on material supply, minimizing global warming, reducing water pollution and producing organic fertilizer. Some series of study are conducted on dried Jatropha curcas Linn. capsule husk (JCL-CH) as bio-gas feedstock. The objective of the study is to create technology for managing JCL integrally according to bio-refinery principle. This paper will present two studies, JCL-CH performance in single stage digester compared with two stages digester in laboratory and palm fiber compared with glass wool as bio-film/bio-carrier in methanogenesis reactor. The studies were conducted in Research Laboratory PT. Bumimas Ekapersada, Bekasi, West Java from March until May 2012. A liter of glass bottle as digester, arranged in Randomized Complete Design, three replications per treatment placed in 32 °C water bath. The bio-gas feedstock was put continuously with Organic Loading Rate – OLR or concentration 1: 12 in single stage compared with 1: 12 and 1: 8 in two stages. The observed parameters were pH, temperature, bio-gas volume, methane concentration, volatile solid and acetic acid concentration. Bio-gas volume was measured by water displacement method and methane concentration was measured by gas chromatography. T-test was used for statistical analysis. The studies showed that two stages digester more efficient since it can increase methane concentration and bio-gas volume/gram VS. The bio-gas volume increase 63.83% in OLR 1: 8. Glass wool was more effective as bio-film carrier compared with palm fiber.

With the various chambers and would digestion take longer than in other mammals? Replies: A friend in animal nutrition is looking up an exact figure, but as he does, here are a few guidelines: Time of digestion largely depends on the type of food an animal ingests: CARNIVORES: short, uncomplicated digestive systems. They eat very high on the food chain (other animals), which provide food stuff which is relatively easy to digest. Hence, rapid digestion. OMNIVORES: medium length, medium complex digestive systems. We eat at all levels of the food chain, and so need a balanced system. Medium time of digestion (roughly 2-10 hours per meal, depending on proportions of carbohydrates, fats, proteins).

Digestion Simulations Digestion Simulations Name: Lisa Location: N/A Country: N/A Date: N/A Question: My 5th grade students are beginning an experiment next week and their hypothesis involves edibility(edibleness?). Is there a way to replicate the stomach in, say, a bottle?? Are there ways to test for edibleness(?) without actually ingesting the experiment yourself? Replies: I would not recommend the idea of a bottle stomach. The stomach digests only proteins anyway with HCl [pH 1.0] which is very, very strong acid that will burn seriously if in contact with skin. The intestine is just as much responsible for digestion of lipids [bile], carbohydrates and remaining proteins using enzymes, many of these you do not want to be handling, let alone purchase. As a high school teacher, I have lab exercises dealing with digestion, but I can not recommend any of these unless you are set up with a functional science laboratory and all the safety equipment necessary.

ANAEROBIC BIOLOGICAL TREATMENT OF PRODUCED WATER  

SciTech Connect

During the production of oil and gas, large amounts of water are brought to the surface and must be disposed of in an environmentally sensitive manner. This is an especially difficult problem in offshore production facilities where space is a major constraint. The chief regulatory criterion for produced water is oil and grease. Most facilities have little trouble meeting this criterion using conventional oil-water separation technologies. However, some operations have significant amounts of naphthenic acids in the water that behave as oil and grease but are not well removed by conventional technologies. Aerobic biological treatment of naphthenic acids in simulated-produced water has been demonstrated by others; however, the system was easily overloaded by the large amounts of low-molecular-weight organic acids often found in produced waters. The objective of this research was to determine the ability of an anaerobic biological system to treat these organic acids in a simulated produced water and to examine the potential for biodegradation of the naphthenic acids in the anaerobic environment. A small fixed-film anaerobic biological reactor was constructed and adapted to treat a simulated produced water. The bioreactor was tubular, with a low-density porous glass packing material. The inocula to the reactor was sediment from a produced-water holding pond from a municipal anaerobic digester and two salt-loving methanogenic bacteria. During start-up, the feed to the reactor contained glucose as well as typical produced-water components. When glucose was used, rapid gas production was observed. However, when glucose was eliminated and the major organic component was acetate, little gas was generated. Methane production from acetate may have been inhibited by the high salt concentrations, by sulfide, or because of the lack, despite seeding, of microbes capable of converting acetate to methane. Toluene, a minor component of the produced water (0.1 g/L) was removed in the reactor. Batch tests were conducted to examine naphthenic acid biodegradability under several conditions. The conditions used were seed from the anaerobic reactor, wetland sediments under aerobic and anaerobic conditions, and a sterile control. The naphthenic acid was from a commercial source isolated from Gulf Coast petroleum as was dosed at 2 mg/mL. The incubations were for 30 days at 30 C. The results showed that the naphthenic acids were not biodegraded under anaerobic conditions, but were degraded under aerobic conditions. Despite poor performance of the anaerobic reactor, it remains likely that anaerobic treatment of acetate, toluene, and, potentially, other produced-water components is feasible.

Production of methane gas from organic fraction municipal solid waste (OFMSW) via anaerobic process: application methodology for the Malaysian condition  

Science Journals Connector (OSTI)

Solid waste management in Malaysia is confronted with many problems, including low collection coverage, irregular collection services, inadequate equipment used for waste collection, crude open dumping and burning without air and water pollution control systems, inadequate legal provisions and resource constraints. These problems have various effects on the development of the solid waste management system in Malaysia. Anaerobic digestion has been suggested as an alternative method for removing high concentrations of organic waste. In this study, two types of anaerobic digesters which are Simulated Landfill Bioreactor (SLBR) and Anaerobic Solid-Liquid (ASL) reactor were proposed. The reactors were operated at a temperature 60°C, analysed for biogas production and volatile fatty acid.

Digestion time  

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

Digestion time Digestion time Name: Don Mancosh Location: N/A Country: N/A Date: N/A Question: I have always given the rule of thumb in class that material we eat is with us for about 24 hours before exiting the body. The question arises about the time value of liquids. Getting a big coke prior to a 3 hour drive generally means that there will be a stop along the way. Is there a generalization made about liquids in the body similar to the one for solid food? Replies: A physician would give a better answer, but I hazard this: the only liquids which people consume (deliberately) in significant quantities are water, ethyl alcohol and various oils. Water and alcohol are absorbed on a time scale of seconds to minutes through the mouth, stomach and digestive tract. The oils are huge molecules, so I'd guess like any other greasy food they get absorbed in the upper digestive tract. Some of them, perhaps the longest and most nonpolar, are not absorbed at all --- cf. the old-time remedy of mineral oil for constipation --- so there should be some average time-before-what's-left-is-excreted such as you're looking for, and my (wild) guess is that it would not differ substantially from that for food. You can define an average lifetime in the body for alcohol, since the natural level is zero. Rough guidelines are widespread in the context of drunk driving laws. But this is not really possible for water. One's body is normally full up to the brim with water, and there's no way for the body to distinguish between water molecules recently absorbed and molecules that've been moping around since the Beatles split up. Thus the water entering the toilet bowl after the pit stop is not in general the same water as was in the big coke. If you were to consider for water just the average time between drinking and peeing, it would seem to depend strongly on how well hydrated the body was before the drink, and how much was drunk. During sustained heavy exertion in the sun and dry air one can easily drink a pint of water an hour without peeing at all. On the other hand, if one is willing to drink enough water fast enough, so as to establish a high excess of body water one can pee 8 ounces 15 minutes or less after drinking 8 ounces.

Mechanisms in anaerobic bioflocculation of wool scouring effluent  

Science Journals Connector (OSTI)

The emulsified grease in wool scouring effluent (WSE) was demonstrably removed by bioflocculation under anaerobic conditions. The addition of anaerobic bacteria from biogas digestion to WSE resulted in grease reduction of 60–80% from the supernatant. Since no significant net grease (supernatant plus sludge) reduction was observed in this system, the grease emulsion from the liquid phase is simply settled by gravity into the sludge phase. However, sterilized sludge did not cause this effect, indicating that bacterial metabolic activity was responsible for the bioflocculation. It was also found that such microbes can successfully survive and multiply in WSE, as a result, the development of a continuous process is possible. The process required a short gentle mixing period of approx. 15 min enable the the sludge to completely contact with WSE, and a longer settling period of 2–4 days to provide an appropriate time for the microbes to destabilize wool grease emulsion and settle to the sludge phase.

Replies: Hmmm.. been a while since I had sophomore biology, so I can't completely answer this one, but I can say a few things. One, since turkeys are birds, and birds as a general rule have not had teeth for several million years at least, the turkey needs a way to mash up its food -- thus, the crop, which is essentially like another stomach: the turkey (and many other birds, for that matter) swallows small stones which serve in lieu of teeth, mashing up food via muscular action in the crop, from whence the "chewed" food moves on into the rest of the digestive tract. As for any other differences, I'll have to leave that to someone else with more ornithological experience...

DEVELOPMENT OF IMPROVED ANAEROBIC GROWTH OF BACILLUS MOJAVENSIS STRAIN JF-2 FOR THE PURPOSE OF IMPROVED ANAEROBIC BIOSURFACTANT PRODUCTION FOR ENHANCED OIL RECOVERY  

SciTech Connect

Our work focuses on the use of microorganisms to recover petroleum hydrocarbons that remain entrapped after current recovery technologies reach their economic limit. Capillary forces between the hydrocarbon and aqueous phases are largely responsible for trapping the hydrocarbons in the pores of the rock and large reductions in the interfacial tension between the hydrocarbon and aqueous phases are needed for hydrocarbon mobilization (1-3, 10, 11). Microorganisms produce a variety of biosurfactants (4), several of which generate the ultra low interfacial tensions needed for hydrocarbon mobilization (4, 5, 8). In particular, the lipopeptide biosurfactant produced by Bacillus mojavensis strain JF-2 reduces the interfacial tension between hydrocarbon and aqueous phases to very low levels (<0.016 mN/m) (8) (9). B. mojavensis JF-2 grows under the environmental conditions found in many oil reservoirs, i. e., anaerobic, NaCl concentrations up to 80 g l{sup -1}, and temperatures up to 45 C (6, 7), making it ideally suited for in situ applications. However, anaerobic growth of B. mojavensis JF-2 was inconsistent and difficult to replicate, which limited its use for in situ applications. Our initial studies revealed that enzymatic digests, such as Proteose Peptone, were required for anaerobic growth of Bacillus mojavensis JF-2. Subsequent purification of the growth-enhancing factor in Proteose Peptone resulted in the identification of the growth-enhancing factor as DNA or deoxyribonucleosides. The addition of salmon sperm DNA, herring sperm DNA, E. coli DNA or synthetic DNA (single or double stranded) to Medium E all supported anaerobic growth of JF-2. Further, we found that JF-2 required all four deoxyribonucleosides (deoxyadeonosine, deoxyguanosine, deoxycytidine and thymidine) for growth under strict anaerobic conditions. The requirement for the deoxyribonucleosides did not occur under aerobic growth conditions. DNA was not used as a sole energy source; sucrose was required for anaerobic growth and biosurfactant production in DNA-supplemented Medium E. In addition to DNA or deoxyribonucleosides, nitrate, amino acids and vitamins were all required for anaerobic growth of JF-2. Bacillus mojavensisT (ABO21191), Bacillus mojavensis, strain ROB2 also required DNA or deoxyribonucleosides for anaerobic growth. The improved anaerobic growth of Bacillus mojavensis JF-2 was a prerequisite for studies that will lead to improved anaerobic biosurfactant production.

Anxiety and Digestion  

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

Anxiety and Digestion Anxiety and Digestion Name: Donna Location: N/A Country: N/A Date: N/A Question: Explain how anxiety may be responsible for slowing down the process of digestion Replies: Your body really has 2 nervous systems. One is the peripheral nervous system that controls how you move and think etc. the other is called the autonomic (not automatic) nervous system It controls all of your everyday functions such as your heart, your blood vessel diameter and your digestive system, etc. There are 2 divisions of the ANS. One is called the parasympathetic and the other is the sympathetic. The parasympathetic is your everyday division, and is usually in control. When you come upon a stressful or dangerous situation, your sympathetic division takes over. It gets you ready to "fight or flee". Some parts of your body are put on alert. Your blood vessels constrict in some areas and dilate in others to get blood flowing to areas that will help you in a dangerous situation and to get glucose (fuel) to those areas quickly. Your heart starts to beat faster to send blood to those areas quicker, your pupils dilate. Other parts of your body are put on hold; those that aren't needed in a danger situation. Your digestive system is one that is put on hold. When you are under stress, your body doesn't know whether you are in danger or not but acts like it is. So if you are under constant stress, your digestive system is affected.

Composting of the solid fraction of digestate derived from pig slurry: Biological processes and compost properties  

Science Journals Connector (OSTI)

Abstract The aim of this paper was to assess the characteristics of the solid fractions (SF) obtained by mechanical separation of digestate, their compostability and compost quality. To do so, the SF of digestates obtained from anaerobic digestion of pig slurry, energy crops and agro-industrial residues were sampled in five plants located in Northern Italy. Results obtained indicated that anaerobic digestion by itself promoted the high biological stability of biomasses with a Potential Dynamic Respiration Index (PDRI) close to 1000 mgO2 kg V S?1 h?1. Subsequent composting of digestates, with an added bulking agent, did not give remarkably different results, and led only to a slight modification of the characteristics of the initial non-composted mixtures; the composts obtained fully respected the legal limits for high quality compost. Chemical studies of organic matter composition of the biomasses by using CP MAS 13C NMR, indicated that the compost was composed of a high relative content of O-alkyl-C (71.47% of total C) (cellulose and hemicelluloses) and a low alkyl-C (12.42%) (i.e. volatile fatty acids, steroid-like molecules, aliphatic biopolymers and proteins).

Experimental co-digestion of corn stalk and vermicompost to improve biogas production  

SciTech Connect

Anaerobic co-digestion of corn stalk and vermicompost (VC) as well as mono-digestion of corn stalk were investigated. Batch mono-digestion experiments were performed at 35 {+-} 1 {sup o}C and initial total solid loading (TSL) ranged from 1.2% to 6.0%. Batch co-digestion experiments were performed at 35 {+-} 1 {sup o}C and initial TSL of 6% with VC proportions ranged from 20% to 80% of total solid (TS). For mono-digestion of corn stalk, a maximum methane yield of 217.60 {+-} 13.87 mL/g TS{sub added} was obtained at initial TSL of 4.8%, and acidification was found at initial TSL of 6.0% with the lowest pH value of 5.10 on day 4. Co-digestion improved the methane yields by 4.42-58.61% via enhancing volatile fatty acids (VFAs) concentration and pH value compared with mono-digestion of corn stalk. The maximum biogas yield of 410.30 {+-} 11.01 mL/g TS{sub added} and methane yield of 259.35 {+-} 13.85 mL/g TS{sub added} were obtained for 40% VC addition. Structure analysis by X-ray diffractometry (XRD) showed that the lowest crystallinity of 35.04 of digested corn stalk was obtained from co-digestion with 40% VC, which decreased 29.4% compared to 49.6 obtained from un-treated corn stalk. It is concluded that co-digestion with VC is beneficial for improving biodigestibility and methane yield from corn stalk.

Greenhouse gases emissions accounting for typical sewage sludge digestion with energy utilization and residue land application in China  

SciTech Connect

Highlights: Black-Right-Pointing-Pointer GHGs emissions from sludge digestion + residue land use in China were calculated. Black-Right-Pointing-Pointer The AD unit contributes more than 97% of total biogenic GHGs emissions. Black-Right-Pointing-Pointer AD with methane recovery is attractive for sludge GHGs emissions reduction. - Abstract: About 20 million tonnes of sludge (with 80% moisture content) is discharged by the sewage treatment plants per year in China, which, if not treated properly, can be a significant source of greenhouse gases (GHGs) emissions. Anaerobic digestion is a conventional sewage sludge treatment method and will continue to be one of the main technologies in the following years. This research has taken into consideration GHGs emissions from typical processes of sludge thickening + anaerobic digestion + dewatering + residue land application in China. Fossil CO{sub 2}, biogenic CO{sub 2}, CH{sub 4,} and avoided CO{sub 2} as the main objects is discussed respectively. The results show that the total CO{sub 2}-eq is about 1133 kg/t DM (including the biogenic CO{sub 2}), while the net CO{sub 2}-eq is about 372 kg/t DM (excluding the biogenic CO{sub 2}). An anaerobic digestion unit as the main GHGs emission source occupies more than 91% CO{sub 2}-eq of the whole process. The use of biogas is important for achieving carbon dioxide emission reductions, which could reach about 24% of the total CO{sub 2}-eq reduction.

Model calibration and validation for OFMSW and sewage sludge co-digestion reactors  

SciTech Connect

Highlights: > Disintegration is the limiting step of the anaerobic co-digestion process. > Disintegration kinetic constant does not depend on the waste particle size. > Disintegration kinetic constant depends only on the waste nature and composition. > The model calibration can be performed on organic waste of any particle size. - Abstract: A mathematical model has recently been proposed by the authors to simulate the biochemical processes that prevail in a co-digestion reactor fed with sewage sludge and the organic fraction of municipal solid waste. This model is based on the Anaerobic Digestion Model no. 1 of the International Water Association, which has been extended to include the co-digestion processes, using surface-based kinetics to model the organic waste disintegration and conversion to carbohydrates, proteins and lipids. When organic waste solids are present in the reactor influent, the disintegration process is the rate-limiting step of the overall co-digestion process. The main advantage of the proposed modeling approach is that the kinetic constant of such a process does not depend on the waste particle size distribution (PSD) and rather depends only on the nature and composition of the waste particles. The model calibration aimed to assess the kinetic constant of the disintegration process can therefore be conducted using organic waste samples of any PSD, and the resulting value will be suitable for all the organic wastes of the same nature as the investigated samples, independently of their PSD. This assumption was proven in this study by biomethane potential experiments that were conducted on organic waste samples with different particle sizes. The results of these experiments were used to calibrate and validate the mathematical model, resulting in a good agreement between the simulated and observed data for any investigated particle size of the solid waste. This study confirms the strength of the proposed model and calibration procedure, which can thus be used to assess the treatment efficiency and predict the methane production of full-scale digesters.

Reduced gas pressure operation of sludge digesters: Expanded studies. Final report  

SciTech Connect

Previous investigations strongly suggested that the municipal anaerobic sludge digestion process could be enhanced by reactor operation with subatmospheric headspace pressures. Enhanced solids destruction and methane production along with increased process stability were observed in these earlier studies. However, due to the small scale of the anaerobic reactors used ( {approx}1.5 L), definitive steady-state measurements could not be obtained. These expanded studies were undertaken to verify and define the magnitude of the benefits that might be obtained with vacuum operation of sludge digesters. Four reactors ({approx}15.0 L) were fed municipal sludge at three different organic loading rates while being maintained with a 15-day solids retention time. One reactor had a constant headspace pressure of 1.02 atm; a second was maintained at 0.75 atm; and the remaining two reactors were operated for the majority of the day at 1.02 atm, and for part of the day with a 0.75 atm headspace pressure. Additional small-scale, batch experiments were performed to help identify controlling digestion mechanisms. The results of these expanded studies indicate that vacuum operation did not yield significant advantages over the organic loading range investigated (0.088 to 0.352 lb VSS/ft{sup 3}{center_dot}d).

Biogas production and feasibility of energy recovery systems for anaerobic treatment of wool-scouring effluent  

Science Journals Connector (OSTI)

The technical and economic feasibility of anaerobic digestion to produce biogas at a small wool-scouring facility in the United States was examined. The facility will process 90,800 kg (200,000 pounds) of greasy wool per year at maximum capacity. Biochemical methane potential experiments showed that anaerobic biodegradation of organic constituents in wool-scouring effluent (WSE) ranged from 17 to 75% on a chemical oxygen demand (COD) basis and produced 0.10–0.39 L methane per gram of WSE COD added. Microbial inhibition was observed when initial WSE concentrations exceeded 1000 mg COD/L. A laboratory-scale continuous reactor operated at organic loading rates of 100–200 mg COD/L/day produced biogas with an average methane content of 75% and provided 72–78% removal of total WSECOD. Life cycle costing predicted that the best alternative for energy recovery at a small wool-scouring facility was to offset natural gas used to heat water for wool-scouring with biogas. Economic feasibility should increase with increasing COD removal, increasing natural gas price, and increasing cost to discharge to the municipal wastewater treatment works. The key anaerobic treatment design challenge will be to maximize WSE organic loading rates while minimizing microbial inhibition.

Mechanism of degradation of wool wax in the anaerobic treatment of woolscouring wastewater  

Science Journals Connector (OSTI)

Results of the anaerobic digestion of a woolscouring wastewater treatment and some considerations about the anaerobic degradation mechanisms of wool wax, are presented. A 57 live anaerobic baffled reactor (ABR) was operated with woolscouring effluent. When organic load varied from 3 to 5 kg COD/m3 d, COD and grease removal ranged from 40 to 55% and 50 to 65%, respectively. With centrifuged effluent, COD removal was 45% to 60%. A 300 m3 ABR was built and operated during two years based on the previous laboratory results. COD removal was between 45% to 18% with organic load of 3 to 10 kg COD/m3 d. With centrifuged effluent, COD efficiencies ranged between 72% and 47%. No inhibition by long chain fatty acids was observed. Considering the results of grease content determination and TLC analysis in both reactors, it could be assumed that wool wax is hydrolyzed forming sterols and free fatty acids and that free fatty acids are degraded while sterols are accumulated in the sludge.

Anaerobic conversion of microalgal biomass to sustainable energy carriers – A review  

Science Journals Connector (OSTI)

This review discusses anaerobic production of methane, hydrogen, ethanol, butanol and electricity from microalgal biomass. The amenability of microalgal biomass to these bioenergy conversion processes is compared with other aquatic and terrestrial biomass sources. The highest energy yields (kJ g?1 dry wt. microalgal biomass) reported in the literature have been 14.8 as ethanol, 14.4 as methane, 6.6 as butanol and 1.2 as hydrogen. The highest power density reported from microalgal biomass in microbial fuel cells has been 980 mW m?2. Sequential production of different energy carriers increases attainable energy yields, but also increases investment and maintenance costs. Microalgal biomass is a promising feedstock for anaerobic energy conversion processes, especially for methanogenic digestion and ethanol fermentation. The reviewed studies have mainly been based on laboratory scale experiments and thus scale-up of anaerobic utilization of microalgal biomass for production of energy carriers is now timely and required for cost-effectiveness comparisons.

PAFC fed by biogas produced by the anaerobic fermentation of the waste waters of a beet-sugar refinery  

SciTech Connect

Beet-washing waters of a beet-sugar refinery carry a high COD (Chemical Oxygen Demand), and their conditioning to meet legal constraints before disposal considerably contributes to the operation costs of the refinery. Their fermentation in an anaerobic digestor could instead produce readily disposable non-polluting waters, fertilizers and biogas, useful to feed a phosphoric acid fuel cell (PAFC) heat and power generator system. A real refinery case is considered in this work, where the electrical characteristics V = V(I) of a laboratory PAFC stack, fueled with a dry simulated reforming gas (having the same H{sub 2} and CO{sub 2} content as the biogas obtainable by the above said anaerobic digestion), are determined. The encouraging results show that a possible market niche for fuel cells, in the food-industry waste partial recovery and residual disposal, deserves attention.

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.

Anaerobic bioflocculation of wool scouring effluent  

Science Journals Connector (OSTI)

A two-stage anaerobic bioflocculation process (ABP) successfully flocculated a high grease (> 15 g/l) wool scouring effluent (WSE). During 110 days of continuous operation, a two-stage laboratory process removed between 70 and 90% grease and 60–86% COD at a combined hydraulic residence time (HRT) of 4–10 days. Grease removal was more difficult with low grease (<10 g/l) WSE. At a HRT of 3 days a single-stage ABP removed 40 and 44% grease at 20 and 37°C, respectively. Methane production and volatile fatty acids consumption were negligible. Most of the grease was removed by flocculation as a result of anaerobic bacterial activity. The supernatant was successfully treated by an aerobic activated sludge process reducing grease concentration from about 1.5 to less than 0.1 g/l in the final effluent at an HRT of 3 days.

Anaerobic fermentation of agricultural residue: potential for improvement and implementation. Final report, Volume II  

SciTech Connect

Earlier studies have shown that although large quantities of agricultural residues are generated on small farms, it was difficult to economically justify use of conventional anaerobic digestion technology, such as used for sewage sludge digestion. A simple, unmixed, earthen-supported structure appeared to be capable of producing significant quantities of biogas at a cost that would make it competitive with many existing fuels. The goal of this study was to define and demonstrate a methane fermentation technology that could be practical and economically feasible on small farms. This study provides the first long term, large scale (reactor volumes of 34 m/sup 3/) parallel testing of the major theory, design, construction, and operation of a low cost approach to animal manure fermentation as compared to the more costly and complex designs. The main objectives were to define the lower limits for successful fermentor operation in terms of mixing, insulation, temperature, feed rate, and management requirements in a cold climate with both pilot scale and full scale fermentors. Over a period of four years, innovative fermentation processes for animal manures were developed from theoretical concept to successful full scale demonstration. Reactors were sized for 50 to 65 dairy animals, or for the one-family dairy size. The results show that a small farm biogas generation system that should be widely applicable and economically feasible was operated successfully for nearly two years. Although this low cost system out-performed the completely mixed unit throughout the study, perhaps the greatest advantage of this approach is its ease of modification, operation, and maintenance.

Innovative wastewater treatment using reversing anaerobic upflow system (RAUS)  

SciTech Connect

Anaerobic processes are widely popular in the treatment of a variety of industrial wastewaters since the development of such high rate treatment processes like upflow anaerobic sludge blanket (UASB), anaerobic filter, and the fluidized-bed process. In order to devise a low cost/high technology system so that it would provide an economical solution to environmentally sound pollution control, the Reversing Anaerobic Upflow System (RAUS) was developed. The system consists of two anaerobic reactors connected to each other. At the beginning, one reactor is fed upwards with wastewater while the other acts as a settling tank. After a set interval of time, the flow is reversed such that the second reactor is fed with wastewater and the first one acts as the settler. This particular feeding pattern had shown improved settling characteristics and granulation of methanogenic biomass from research carried out at the Hannover University with different wastewaters. The biological reaction vessels to which wastewater is introduced intermittently functions basically as a sludge blanket type reactor although the costly integrated settling devices present in a typical UASB system are avoided. The RAUS combines three principle reactor configurations: (1) conventional with sludge recycling; (2) fill and draw or sequential batch, inflow maintained constant during feeding; (3) upflow anaerobic sludge blanket. A pilot scale RAUS was operated for 400 days using distillery wastewater consisting of molasses slop and bottle washing water mixed in the ratio 1:1. This paper discusses the results of pilot scale experiments.

Limiting factors and microbial organometallic transformations in anaerobic subsurface environments  

SciTech Connect

Microbial communities from subsurface materials were analyzed for microbial community-particle size relationships, effects of arsenic and mercury compounds on microbial community structure, and limiting factors influencing mercury volatilization under aerobic and anaerobic conditions. The microbial communities showed strong relationships to particle size and size distribution. Major differences were found in relation to aerobic and anaerobic populations and for aerobic populations between the largest and smallest fractions. Under aerobic conditions, a significant increase in low nutrient responsive microbes occurred. After exposure to four metal compounds (phenylmercuric acetate (PMA), mercuric chloride (HgCl{sub 2}), phenylarsonic acid (PAA), and sodium arsenate (Na{sub 2}AsO{sub 4})) major changes in populations occurred. Previous exposure to these metals increased the aerobic and anaerobic populations of GS-9, indicating an adaptive response. In GS-20, previous exposure to all four compounds caused a decrease in both the aerobic and anaerobic populations. The effect was most pronounced in sediments treated with PMA or HgCl{sub 2}. Limiting nutritional factors for the volatilization of mercury under aerobic and anaerobic conditions were identified in control and PMA impacted samples from GS-9 and GS-20.

Environmental assessment of energy production by combustion of biogas provided by the anaerobic digestion of agricultural biomass  

Science Journals Connector (OSTI)

This paper tries to compare the environmental impacts of energy production using agricultural biomass and energy production using traditional reactor systems (natural gas and fuel oil) by using the Life Cycle Assessment (LCA) methodology. In order to make this comparison, the impact assessment methods CML 2 BASELINE 2000 (problem oriented method) and ECOINDICATOR 99 (damage oriented method) are used. The heat produced by cogeneration is intended to feed a heating network connected to 16 dwellings. The results show that the use of biogas reduces the emissions taking part in the global warming potential and reduces the global environmental impact.

Analysis, anaerobic treatment and ozonation of wool scouring wastewater  

SciTech Connect

Wool scouring effluents (WSE) were analyzed by high-resolution gas chromatography-mass spectrometry (HRGC-MS), and then exposed to anaerobic biological treatment using laboratory scale fixed-bed filters. This resulted in a nearly 50% reduction in chemical oxygen demand (COD). Ozonation of the effluent from the biological step led to an even further decrease in total organic carbon (TOC). The fatty acid content of the WSE was affected by both biological treatment and ozonation. Finally, steroids in the WSE underwent reduction reactions when exposed to the anaerobic biological treatment.

Crab digestive phospholipase: A new invertebrate member  

Science Journals Connector (OSTI)

Crab digestive phospholipase (CDPL) was purified from the hepatopancreas of Carcinus mediterraneus crabs. Homogeneous enzyme was obtained after two chromatography steps: anion exchange and size exclusion HPLC column. Homogeneous CDPL has a molecular mass of 14 kDa as determined by SDS/PAGE analysis. Unlike known digestive phospholipases like porcine PLA2 (PPPL), CDPL displayed its maximal activity at 50 °C and not at 37 °C. A specific activity of 40 U/mg for the purified CDPL was measured using PC as substrate under optimal conditions (pH 8 and 50 °C) in the presence of 8 mM sodium deoxycholate (NaDC) and 10 mM CaCl2. In contrast to PPPL, purified CDPL was completely inactivated at 60 °C. The N-terminal sequence was determined by automatic Edman degradation. No similarity between 12 N-terminal amino acid residues of CDPL was found with those of known digestive phospholipases. CDPL appears to be a new member of invertebrate phospholipases, and it is potentially useful for treat phospholipid-rich industrial effluents, or to synthesize useful chemical compounds which can be used in the food industry.

Method of digesting an explosive nitro compound  

DOE Patents (OSTI)

The present invention is a process wherein bleaching oxidants are used to digest explosive nitro compounds. The process has an excellent reaction rate for digesting explosives and operates under multivariate conditions. Reaction solutions may be aqueous, non-aqueous or a combination thereof, and can also be any pH, but preferably have a pH between 2 and 9. The temperature may be ambient as well as any temperature above which freezing of the solution would occur and below which any degradation of the bleaching oxidant would occur or below which any explosive reaction would be initiated. The pressure may be any pressure, but is preferably ambient or atmospheric, or a pressure above a vapor pressure of the aqueous solution to avoid boiling of the solution. Because the bleaching oxidant molecules are small, much smaller than an enzyme molecule for example, they can penetrate the microstructure of plastic explosives faster. The bleaching oxidants generate reactive hydroxyl radicals, which can destroy other organic contaminants, if necessary, along with digesting the explosive nitro compound.

The results of a project to produce methane using the manure from zoo animals as a feedstock is presented. Two digesters are in operation, the first (built in 1974) utilizing wastes from the Hippo House and a second (built in 1980) utilizing wastes from the Elephant House. Demonstrations on the utilization of the gas were performed during zoo exhibits. The Elephant House Digester has a capacity of 4200 gallons and a floating gas dome which can retain at least 150 cu ft of gas. Solar energy has been incorporated into the design to maintain digester temperature at 95/sup 0/F. The system produces 50 cu ft per day. After cleaning the gas, it is used to generate electricity to power an electric light, a roof fan, and an air conditioner. The gas is also used to operate a gas range and a gas lamp. During the opening day exhibit, 50 meals were cooked using the bio-gas from just 2 elephants. (DMC)

Complete genome sequence of Peptoniphilus sp. strain ING2-D1G isolated from a mesophilic lab-scale completely stirred tank reactor utilizing maize silage in co-digestion with pig and cattle manure for biomethanation  

Science Journals Connector (OSTI)

Abstract The bacterium Peptoniphilus sp. strain ING2-D1G (DSM 28672), a mesophilic and obligate anaerobic bacterium belonging to the order Clostridiales was isolated from a biogas-producing lab-scale completely stirred tank reactor (CSTR) optimized for anaerobic digestion of maize silage in co-fermentation with pig and cattle manure. In this study, the whole genome sequence of Peptoniphilus sp. strain ING2-D1G, a new isolate potentially involved in protein breakdown and acidogenesis during biomass degradation, is reported. The chromosome of this strain is 1.6 Mb in size and encodes genes predicted to be involved in the production of acetate, lactate and butyrate specifying the acidogenic metabolism of the isolate.

Metagenome of an Anaerobic Microbial Community Decomposing Poplar Wood Chips  

SciTech Connect

This study describes the composition and metabolic potential of a lignocellulosic biomass degrading community that decays poplar wood chips under anaerobic conditions. We examined the community that developed on poplar biomass in a non-aerated bioreactor over the course of a year, with no microbial inoculation other than the naturally occurring organisms on the woody material. The composition of this community contrasts in important ways with biomass-degrading communities associated with higher organisms, which have evolved over millions of years into a symbiotic relationship. Both mammalian and insect hosts provide partial size reduction, chemical treatments (low or high pH environments), and complex enzymatic 'secretomes' that improve microbial access to cell wall polymers. We hypothesized that in order to efficiently degrade coarse untreated biomass, a spontaneously assembled free-living community must both employ alternative strategies, such as enzymatic lignin depolymerization, for accessing hemicellulose and cellulose and have a much broader metabolic potential than host-associated communities. This would suggest that such a community would make a valuable resource for finding new catalytic functions involved in biomass decomposition and gaining new insight into the poorly understood process of anaerobic lignin depolymerization. Therefore, in addition to determining the major players in this community, our work specifically aimed at identifying functions potentially involved in the depolymerization of cellulose, hemicelluloses, and lignin, and to assign specific roles to the prevalent community members in the collaborative process of biomass decomposition. A bacterium similar to Magnetospirillum was identified among the dominant community members, which could play a key role in the anaerobic breakdown of aromatic compounds. We suggest that these compounds are released from the lignin fraction in poplar hardwood during the decay process, which would point to lignin-modification or depolymerization under anaerobic conditions.

Sequential anaerobic-aerobic degradation of indigenous PCBs in a contaminated soil matrix  

SciTech Connect

Many industrial locations, including the US Department of Energy`s, have identified needs for treatment of polychlorinated biphenyl (PCB) wastes and remediation of PCB-contaminated sites. Biodegradation of PCBs is a potentially effective technology for the treatment of PCB-contaminated soils and sludges; however, a practicable remediation technology has not yet been demonstrated. A biological treatment technology is likely to consist of an anaerobic fermentation step in which PCB dechlorination takes place producing PCBs with fewer chlorines. These products are then more susceptible to aerobic mineralization. In laboratory experiments, soil slurry bioreactors inoculated with microorganisms extracted from PCB-contaminated sediments from the Hudson River and Woods Pond have been used to obtain anaerobic dechlorination of PCBs in soil slurry reactors. The anaerobic dechlorination was followed by qualitative estimation of the effect of aerobic fermentation of the dechlorination products based on literature data. The sequential anaerobic-(simulated) aerobic treatment constituted an improvement compared anaerobic treatment alone.

Sonochemical Digestion of Soil and Sediment Samples  

SciTech Connect

This work was performed as part of a broader effort to automate analytical methods for determination of plutonium and other radioisotopes in environmental samples. The work described here represented a screening study to determine the potential for applying ultrasonic irradiation to sample digestion. Two standard reference materials (SRMs) were used in this study: Columbia River Sediment and Rocky Flats Soil. The key experiments performed are listed below along with a summary of the results. The action of nitric acid, regardless of its concentration and liquid-to-solid ratio, did not achieve dissolution efficiency better that 20%. The major fraction of natural organic matter (NOM) remained undissolved by this treatment. Sonication did not result in improved dissolution for the SRMs tested. The action of hydrofluoric acid at concentrations of 8 M and higher achieved much more pronounced dissolution (up to 97% dissolved for the Rocky Flats soil sample and up to 78% dissolved for the Columbia River Sediment sample). Dissolution efficiency remains constant for solid-to-liquid ratios of up to 0.05 to 1 and decreases for the higher loadings of the solid phase. Sonication produced no measurable effect in improving the dissolution of the samples compared with the control digestion experiments. Combined treatment of the SRM by mixtures of HNO3 and HF showed inferior performance compared with the HF alone. An adverse effect of sonication was found for the Rocky Flats soil material, which became more noticeable at higher HF concentrations. Sonication of the Columbia River sediment samples had no positive effect in the mixed acid treatment. The results indicate that applying ultrasound in an isolated cup horn configuration does not offer any advantage over conventional ''heat and mix'' treatment for dissolution of the soil and sediment based on the SRM examined here. This conclusion, however, is based on an approach that uses gravimetric analysis to determine gross dissolution efficiency. This approach does not allow any conclusion regarding the possible advantage of sonication in selective dissolution of plutonium traces incorporated into an inorganic or organic fraction of the samples.

Can Delignification Decrease Cellulose Digestibility in Acid Pretreated Corn Stover?  

SciTech Connect

It has previously been shown that the improved digestibility of dilute acid pretreated corn stover is at least partially due to the removal of xylan and the consequent increase in accessibility of the cellulose to cellobiohydrolase enzymes. We now report on the impact that lignin removal has on the accessibility and digestibility of dilute acid pretreated corn stover. Samples of corn stover were subjected to dilute sulfuric acid pretreatment with and without simultaneous (partial) lignin removal. In addition, some samples were completely delignified after the pretreatment step using acidified sodium chlorite. The accessibility and digestibility of the samples were tested using a fluorescence-labeled cellobiohydrolase (Trichoderma reesei Cel7A) purified from a commercial cellulase preparation. Partial delignification of corn stover during dilute acid pretreatment was shown to improve cellulose digestibility by T. reesei Cel7A; however, decreasing the lignin content below 5% (g g{sup -1}) by treatment with acidified sodium chlorite resulted in a dramatic reduction in cellulose digestibility. Importantly, this effect was found to be enhanced in samples with lower xylan contents suggesting that the near complete removal of xylan and lignin may cause aggregation of the cellulose microfibrils resulting in decreased cellulase accessibility.

Anaerobic Biotransformation and Mobility of Pu and of Pu-EDTA  

SciTech Connect

The enhanced mobility of radionuclides by co-disposed chelating agent, ethylenediaminetetraacetate (EDTA), is likely to occur only under anaerobic conditions. Our extensive effort to enrich and isolate anaerobic EDTA-degrading bacteria has failed. Others has tried and also failed. To explain the lack of anaerobic biodegradation of EDTA, we proposed that EDTA has to be transported into the cells for metabolism. A failure of uptake may contribute to the lack of EDTA degradation under anaerobic conditions. We demonstrated that an aerobic EDTA-degrading bacterium strain BNC1 uses an ABC-type transporter system to uptake EDTA. The system has a periplasmic binding protein that bind EDTA and then interacts with membrane proteins to transport EDTA into the cell at the expense of ATP. The bind protein EppA binds only free EDTA with a Kd of 25 nM. The low Kd value indicates high affinity. However, the Kd value of Ni-EDTA is 2.4 x 10^(-10) nM, indicating much stronger stability. Since Ni and other trace metals are essential for anaerobic respiration, we conclude that the added EDTA sequestrates all trace metals and making anaerobic respiration impossible. Thus, the data explain the lack of anaerobic enrichment cultures for EDTA degradation. Although we did not obtain an EDTA degrading culture under anaerobic conditions, our finding may promote the use of certain metals that forms more stable metal-EDTA complexes than Pu(III)-EDTA to prevent the enhanced mobility. Further, our data explain why EDTA is the most dominant organic pollutant in surface waters, due to the lack of degradation of certain metal-EDTA complexes.

Treatment of wool scouring effluent using anaerobic biological and chemical flocculation  

Science Journals Connector (OSTI)

The most widely used treatment of wool scouring effluent (WSE) in Australia is lagooning (anaerobic and aerobic). As the pressure to devise a more environmentally acceptable treatment method increases there is a need to study alternative, efficient biological treatment systems for WSE. In this study, laboratory and pilot-scale anaerobic biological and chemical flocculation treatment processes were investigated for removing the pollutants (mainly wool grease) from WSE. Anaerobic biological treatment utilises the natural microbial flora to destabilise and bioflocculate the WSE resulting in the settling of wool grease from the bulk liquid. Batch trials showed a grease reduction by anaerobic bioflocculation of between 30% (pilot scale) and 50% (laboratory scale) over 8 days. However, the destabilisation of the wool grease emulsion after only 2–3 days resulted in a total grease reduction of >80% after addition of a polymeric flocculant. A laboratory anaerobic bioflocculation-chemical flocculation process gave promising results by removing >90% grease at hydraulic retention times of 1–2 days. In the pilot-scale the same process resulted in up to 80% grease removal efficiency. The results of this study indicate that anaerobic biological and chemical treatment of WSE is a promising alternative treatment system compared to other chemical or natural (lagooning) treatment systems. Our approach suggests adding a flocculant to aid the separation of biologically coagulated grease from the bulk liquid. A final low-level aerobic polishing step will be necessary to meet effluent disposal guidelines

Anaerobic bioflocculation of wool scouring effluent: the influence of non-ionic surfactant on efficiency  

Science Journals Connector (OSTI)

Wool scouring effluent (WSE) contains high concentrations of wool grease emulsified by non-ionic surfactants (nonylphenol polyethoxylates — NPEO). The short-term treatment (1–7 days) of this effluent with anaerobic bacteria resulted in partial grease flocculation. However the efficiency of this process varied largely (30% to 80%) with the source of wool scouring effluent used. The concentration of free surfactant, rather than total surfactant, was found to be the likely reason for the variation in efficiency. In order to elucidate the mechanisms of anaerobic biological flocculation a detailed surfactant analysis was performed. This revealed that anaerobic microbes (taken from sludge of a municipal wastewater treatment plant) had an ability to partially degrade NPEO by shortening the hydrophilic ethoxylate chain causing coagulation and subsequent flocculation of wool grease from the liquor.

Evaluation of a sequential aerobicâ??anaerobic treatment of municipal solid waste in a bioreactor landfill  

Science Journals Connector (OSTI)

A sequential aerobic-anaerobic bioreactor landfill was operated and monitored over a period of 184 days. The bioreactor was filled with 120 kg of organic fraction of Municipal Solid Waste. Leachate recirculation was applied. The results showed rapid degradation of organic matter with rapid settlement during the aerobic period. The initial COD and BOD5 were reduced from 46,500 and 41,500 mg/L to 9000 and 6000 mg/L, respectively, within one month. The SO42? concentration, during the anaerobic period, was decreased from 1500 mg/L to 250 mg/L. The sequential treatment had positive effects on nitrification and denitrification efficiencies.

Separate collection of household food waste for anaerobic degradation - Comparison of different techniques from a systems perspective  

SciTech Connect

Highlight: Black-Right-Pointing-Pointer Four modern and innovative systems for household food waste collection are compared. Black-Right-Pointing-Pointer Direct emissions and resource use were based on full-scale data. Black-Right-Pointing-Pointer Conservation of nutrients/energy content over the system was considered. Black-Right-Pointing-Pointer Systems with high energy/nutrient recovery are most environmentally beneficial. - Abstract: Four systems for household food waste collection are compared in relation the environmental impact categories eutrophication potential, acidification potential, global warming potential as well as energy use. Also, a hotspot analysis is performed in order to suggest improvements in each of the compared collection systems. Separate collection of household food waste in paper bags (with and without drying prior to collection) with use of kitchen grinders and with use of vacuum system in kitchen sinks were compared. In all cases, food waste was used for anaerobic digestion with energy and nutrient recovery in all cases. Compared systems all resulted in net avoidance of assessed environmental impact categories; eutrophication potential (-0.1 to -2.4 kg NO{sub 3}{sup -}eq/ton food waste), acidification potential (-0.4 to -1.0 kg SO{sub 2}{sup -}eq/ton food waste), global warming potential (-790 to -960 kg CO{sub 2}{sup -}eq/ton food waste) and primary energy use (-1.7 to -3.6 GJ/ton food waste). Collection with vacuum system results in the largest net avoidance of primary energy use, while disposal of food waste in paper bags for decentralized drying before collection result in a larger net avoidance of global warming, eutrophication and acidification. However, both these systems not have been taken into use in large scale systems yet and further investigations are needed in order to confirm the outcomes from the comparison. Ranking of scenarios differ largely if considering only emissions in the foreground system, indicating the importance of taking also downstream emissions into consideration when comparing different collection systems. The hot spot identification shows that losses of organic matter in mechanical pretreatment as well as tank connected food waste disposal systems and energy in drying and vacuum systems reply to the largest impact on the results in each system respectively.

Method for digesting a nitro-bearing explosive compound  

DOE Patents (OSTI)

The present invention is a process wherein superoxide radicals from superoxide salt are used to break down the explosive compounds. The process has an excellent reaction rate for degrading explosives, and operates at ambient temperature and atmospheric pressure in aqueous or non-aqueous conditions. Because the superoxide molecules are small, much smaller than an enzyme molecule for example, they can penetrate the microstructure of plastic explosives faster. The superoxide salt generates reactive hydroxyl radicals, which can destroy other organic contaminants, if necessary, along with digesting the explosive nitro-bearing compound.

Low dimensional model of heart rhythm dynamics as a tool for diagnosing the anaerobic threshold  

SciTech Connect

We report preliminary results on describing the dependence of the heart rhythm variability on the stress level by using qualitative, low dimensional models. The reconstruction of macroscopic heart models yielding cardio cycles (RR-intervals) duration was based on actual clinical data. Our results show that the coefficients of the low dimensional models are sensitive to metabolic changes. In particular, at the transition between aerobic and aerobic-anaerobic metabolism, there are pronounced extrema in the functional dependence of the coefficients on the stress level. This strong sensitivity can be used to design an easy indirect method for determining the anaerobic threshold. This method could replace costly and invasive traditional methods such as gas analysis and blood tests. {copyright} {ital 1997 American Institute of Physics.}

The metagenome of an anaerobic microbial community decomposing poplar wood chips  

SciTech Connect

This study describes the composition and metabolic potential of a lignocellulosic biomass degrading community that decays poplar wood chips under anaerobic conditions. We examined the community that developed on poplar biomass in a non-aerated bioreactor over the course of a year, with no microbial inoculation other than the naturally occurring organisms on the woody material. The composition of this community contrasts in important ways with biomass-degrading communities associated with higher organisms, which have evolved over millions of years into a symbiotic relationship. Both mammalian and insect hosts provide partial size reduction, chemical treatments (low or high pH environments), and complex enzymatic 'secretomes' that improve microbial access to cell wall polymers. We hypothesized that in order to efficiently degrade coarse untreated biomass, a spontaneously assembled free-living community must both employ alternative strategies, such as enzymatic lignin depolymerization, for accessing hemicellulose and cellulose and have a much broader metabolic potential than host-associated communities. This would suggest that such a community would make a valuable resource for finding new catalytic functions involved in biomass decomposition and gaining new insight into the poorly understood process of anaerobic lignin depolymerization. Therefore, in addition to determining the major players in this community, our work specifically aimed at identifying functions potentially involved in the depolymerization of cellulose, hemicelluloses, and lignin, and to assign specific roles to the prevalent community members in the collaborative process of biomass decomposition. A bacterium similar to Magnetospirillum was identified among the dominant community members, which could play a key role in the anaerobic breakdown of aromatic compounds. We suggest that these compounds are released from the lignin fraction in poplar hardwood during the decay process, which would point to lignin-modification or depolymerization under anaerobic conditions.

Nitrogen content, amino acid composition and digestibility of fungi from a nutritional perspective in animal mycophagy  

Science Journals Connector (OSTI)

Fungi comprise a major part of the diet of many animals. Even so, the nutritional value of fungi has been much debated, with some arguing that fungi are nutritionally poor. However, the chemical composition of fungi and of the biology of the animals that eat them are not well understood, particularly in reference to amino acid (AA) composition of fungi and digestibility of fungal protein. We analysed fibre, total nitrogen (N), available N, and AA contents and measured in vitro digestibility of a wide range of epigeous and hypogeous fungi collected in Australia and the USA to test three hypotheses: (i) fungi are nutritionally poor because they contain few nutrients or are otherwise of low digestibility, (ii) fungi vary substantially in their nutritional composition; and (iii) animals can counter this variable quality by eating diverse taxa. Resultant data indicate many fungi are a reasonable source of \\{AAs\\} and digestible nitrogen. However, they vary highly between species in AA content, and the protein has a poor balance of digestible AAs. This helps explain why many mycophagous animals eat a wide array of fungi and often have digestive strategies to cope with fungi, such as foregut fermentation. Another common strategy is to supplement the diet with high quality protein, such as insect protein. Accordingly, evaluating nutritional value of fungi requires consideration of physiology of the animal species and their whole diet.

Coupling between H+ transport and anaerobic glycolysis in turtle urinary bladder: effect of inhibitors of H+ ATPase  

SciTech Connect

The coupling between H+ transport (JH) and anaerobic glycolysis was examined in vitro in an anaerobic preparation of turtle urinary bladder. JH was measured as the short-circuit current after Na+ transport was abolished with ouabain and by pH stat titration. The media were gassed with N2 and 1% CO2 (PO2 less than 0.5 mm Hg) and contained 10 mM glucose. Under these conditions, JH was not inhibited by 3 mM serosal (S) cyanide or by 0.1 mM mucosal (M) dinitrophenol. Control anaerobic lactate production (Jlac) of 47 bladders was plotted as a function of simultaneously measured JH. The slope of Jlac on JH was 0.58

Enrichment and optimization of anaerobic bacterial mixed culture for conversion of syngas to ethanol  

Science Journals Connector (OSTI)

Abstract The main aim of the present study was to enrich anaerobic mixed bacterial culture capable of producing ethanol from synthesis gas fermentation. Screening of thirteen anaerobic strains together with enrichment protocol helped to develop an efficient mixed culture capable of utilizing syngas for ethanol production. Physiological and operational parameters were optimized for enhanced ethanol production. The optimized value of operational parameters i.e. initial media pH, incubation temperature, initial syngas pressure, and agitation speed were 6.0 ± 0.1, 37 °C, 2 kg cm?2 and 100 rpm respectively. Under these conditions ethanol and acetic acid production by the selected mixed culture were 1.54 g L?1 and 0.8 g L?1 respectively. Furthermore, up-scaling studies in semi-continuous fermentation mode further enhanced ethanol and acetic acid production up to 2.2 g L?1 and 0.9 g L?1 respectively. Mixed culture TERI SA1 was efficient for ethanol production by syngas fermentation.

Mathematical modeling of the effects of aerobic and anaerobic chelate bioegradation on actinide speciation.  

SciTech Connect

Biodegradation of natural and anthropogenic chelating agents directly and indirectly affects the speciation, and, hence, the mobility of actinides in subsurface environments. We combined mathematical modeling with laboratory experimentation to investigate the effects of aerobic and anaerobic chelate biodegradation on actinide [Np(IV/V), Pu(IV)] speciation. Under aerobic conditions, nitrilotriacetic acid (NTA) biodegradation rates were strongly influenced by the actinide concentration. Actinide-chelate complexation reduced the relative abundance of available growth substrate in solution and actinide species present or released during chelate degradation were toxic to the organisms. Aerobic bio-utilization of the chelates as electron-donor substrates directly affected actinide speciation by releasing the radionuclides from complexed form into solution, where their fate was controlled by inorganic ligands in the system. Actinide speciation was also indirectly affected by pH changes caused by organic biodegradation. The two concurrent processes of organic biodegradation and actinide aqueous chemistry were accurately linked and described using CCBATCH, a computer model developed at Northwestern University to investigate the dynamics of coupled biological and chemical reactions in mixed waste subsurface environments. CCBATCH was then used to simulate the fate of Np during anaerobic citrate biodegradation. The modeling studies suggested that, under some conditions, chelate degradation can increase Np(IV) solubility due to carbonate complexation in closed aqueous systems.

Anaerobic biprocessing of low rank coals. Final technical report, September 12, 1990--August 10, 1993  

SciTech Connect

Coal solubilization under aerobic conditions results in oxygenated coal product which, in turn, makes the coal poorer fuel than the starting material. A novel approach has been made in this project is to remove oxygen from coal by reductive decarboxylation. In Wyodak subbituminous coal the major oxygen functionality is carboxylic groups which exist predominantly as carboxylate anions strongly chelating metal cations like Ca{sup 2+} and forming strong macromolecular crosslinks which contribute in large measure to network polymer structure. Removal of the carboxylic groups at ambient temperature by anaerobic organisms would unravel the macromoleculer network, resulting in smaller coal macromolecules with increased H/C ratio which has better fuel value and better processing prospects. These studies described here sought to find biological methods to remove carboxylic functionalities from low rank coals under ambient conditions and to assess the properties of these modified coals towards coal liquefaction. Efforts were made to establish anaerobic microbial consortia having decarboxylating ability, decarboxylate coal with the adapted microbial consortia, isolate the organisms, and characterize the biotreated coal products. Production of CO{sup 2} was used as the primary indicator for possible coal decarboxylation.

NREL: News - NREL Finds a New Cellulose Digestion Mechanism by a  

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

114 114 NREL Finds a New Cellulose Digestion Mechanism by a Fast-eating Enzyme CelA digests cellulose faster than enzymes from commercial preparations January 2, 2014 Researchers at the Energy Department's National Renewable Energy Laboratory (NREL) have discovered that an enzyme from a microorganism first found in the Valley of Geysers on the Kamchatka Peninsula in Russia in 1990 can digest cellulose almost twice as fast as the current leading component cellulase enzyme on the market. If the enzyme continues to perform well in larger tests, it could help drive down the price of making lignocellulosic fuels, from ethanol to other biofuels that can be dropped into existing infrastructure.

Biotransformation of monoterpenes, bile acids, and other isoprenoids in anaerobic ecosystems  

Science Journals Connector (OSTI)

Isoprenoic compounds play a major part in the global carbon cycle. Biosynthesis and mineralization by aerobic bacteria have been intensively studied. This review describes our knowledge on the anaerobic metabolism of isoprenoids, mainly by denitrifying and fermentative bacteria. Nitrate-reducing ?-Proteobacteria were isolated on monoterpenes as sole carbon source and electron donor. Thauera spp. were obtained on the oxygen-containing monoterpenes linalool, menthol, and eucalyptol. Several strains of Alcaligenes defragrans were isolated on unsaturated monoterpenes as growth substrates. A novel denitrifying ?-Proteobacterium, strain 72Chol, mineralizes cholesterol completely to carbon dioxide. Physiological studies showed the presence of several oxidative pathways in these microorganisms. Investigations by organic geochemists indicate possible contributions of anaerobes to early diagenetic processes. One example, the formation of p-cymene from monoterpenes, could indeed be detected in methanogenic enrichment cultures. In man, cholic acid (CA) and chenodeoxycholic acid (CDCA), are synthesized in the liver from cholesterol. During their enterohepatic circulation, bile acids are biotransformed by the intestinal microflora into a variety of metabolites. Known bacterial biotransformations of conjugated bile acids include: deconjugation, oxidation of hydroxy groups at C-3, C-7 and C-12 with formation of oxo bile acids and reduction of these oxo groups to either ?- or ?-configuration. Quantitatively, the most important bacterial biotransformation is the 7?-dehydroxylation of CA and CDCA yielding deoxycholic acid and lithocholic acid, respectively. The 7?-dehydroxylation of CA occurs via a novel six-step biochemical pathway. The genes encoding several enzymes that either transport bile acids or catalyze various reactions in the 7?-dehydroxylation pathway of Eubacterium sp. strain VPI 12708 have been cloned, expressed in Escherichia coli, purified, and characterized.

Efficient and Specific Trypsin Digestion of Microgram to Nanogram Quantities of Proteins in Organic-Aqueous Solvent Systems  

SciTech Connect

Mass spectrometry-based identification of the components of multiprotein complexes often involves solution-phase proteolytic digestion of the complex. The affinity purification of individual protein complexes often yields nanogram to low-microgram amounts of protein, which poses several challenges for enzymatic digestion and protein identification. We tested different solvent systems to optimize trypsin digestions of samples containing limited amounts of protein for subsequent analysis by LC-MS-MS. Data collected from digestion of 10-, 2-, 1-, and 0.2- g portions of a protein standard mixture indicated that an organicaqueous solvent system containing 80% acetonitrile consistently provided the most complete digestion, producing more peptide identifications than the other solvent systems tested. For example, a 1-h digestion in 80% acetonitrile yielded over 52% more peptides than the overnight digestion of 1 g of a protein mixture in purely aqueous buffer. This trend was also observed for peptides from digested ribosomal proteins isolated from Rhodopseudomonas palustris. In addition to improved digestion efficiency, the shorter digestion times possible with the organic solvent also improved trypsin specificity, resulting in smaller numbers of semitryptic peptides than an overnight digestion protocol using an aqueous solvent. The technique was also demonstrated for an affinityisolated protein complex, GroEL. To our knowledge, this report is the first using mass spectrometry data to show a linkage between digestion solvent and trypsin specificity. Mass spectrometry (MS) has become a widely used method for studying proteins, protein complexes, and whole proteomes because of innovations in soft ionization techniques, bioinformatics, and chromatographic separation techniques.1-7 An example of a high-throughput mass spectrometry strategy commonly used for this purpose is a variation of the "shotgun" approach, involving in-solution digestion of a protein complex followed by onedimensional (1D) or two-dimensional (2D) liquid chromatography (LC) coupled with electrospray ionization (ESI) MS-MS.6-8 One of the applications of this method is for characterizing multiprotein complexes by identifying large numbers of proteins in a single data acquisition.9 Large-scale implementations of this strategy have been reported for yeast and Escherichia coli.10-12 To achieve a goal of characterizing large numbers of protein complexes13 isolated by affinity purification from Rhodopseudomonas palustris,14 an efficient protocol for digesting these complexes is required.

Overcoming the anaerobic hurdle in phenotypic microarrays: Generation andvisualization of growth curve data for Desulfovibrio vulgaris Hildenborough  

SciTech Connect

Growing anaerobic microorganisms in phenotypic microarrays (PM) and 96-well microtiter plates is an emerging technology that allows high throughput survey of the growth and physiology and/or phenotype of cultivable microorganisms. For non-model bacteria, a method for phenotypic analysis is invaluable, not only to serve as a starting point for further evaluation, but also to provide a broad understanding of the physiology of an uncharacterized wild-type organism or the physiology/phenotype of a newly created mutant of that organism. Given recent advances in genetic characterization and targeted mutations to elucidate genetic networks and metabolic pathways, high-throughput methods for determining phenotypic differences are essential. Here we outline challenges presented in studying the physiology and phenotype of a sulfate reducing anaerobic delta proteobacterium, Desulfovibrio vulgaris Hildenborough. Modifications of the commercially available OmniLog(TM) system (Hayward, CA) for experimental setup, and configuration, as well as considerations in PM data analysis are presented. Also highlighted here is data viewing software that enables users to view and compare multiple PM data sets. The PM method promises to be a valuable strategy in our systems biology approach to D. vulgaris studies and is readily applicable to other anaerobic and aerobic bacteria.

Impact of ArcA loss in Shewanella oneidensis revealed by comparative proteomics under aerobic and anaerobic conditions  

SciTech Connect

Shewanella inhabit a wide variety of niches in nature and can utilize a broad spectrum of electron acceptors under anaerobic conditions. How they modulate their gene expression to adapt is poorly understood. ArcA, homologue of a global regulator controlling hundreds of genes involved in aerobic and anaerobic respiration in E. coli, was shown to be important in aerobiosis/anaerobiosis of S. oneidensis as well. Loss of ArcA, in addition to altering transcription of many genes, resulted in impaired growth under aerobic condition, which was not observed in E. coli. To further characterize the impact of ArcA loss on gene expression on the level of proteome under aerobic and anaerobic conditions, liquid-chromatography-mass-spectrometry (LC-MS) based proteomic approach was employed. Results show that ArcA loss led to globally altered gene expression, generally consistent with that observed with transcripts. Comparison of transcriptomic and proteomic data permitted identification of 17 high-confidence ArcA targets. Moreover, our data indicate that ArcA is required for regulation of cytochrome c proteins, and the menaquinone level may play a role in regulating ArcA as in E. coli. Proteomic-data-guided growth assay revealed that the aerobic growth defect of ArcA mutant is presumably due to impaired peptide utilization.

Improved bio-energy yields via sequential ethanol fermentation and biogas digestion of steam exploded oat straw  

Science Journals Connector (OSTI)

Using standard laboratory equipment, thermochemically pretreated oat straw was enzymatically saccharified and fermented to ethanol, and after removal of ethanol the remaining material was subjected to biogas digestion. A detailed mass balance calculation shows that, for steam explosion pretreatment, this combined ethanol fermentation and biogas digestion converts 85–87% of the higher heating value (HHV) of holocellulose (cellulose and hemicellulose) in the oat straw into biofuel energy. The energy (HHV) yield of the produced ethanol and methane was 9.5–9.8 MJ/(kg dry oat straw), which is 28–34% higher than direct biogas digestion that yielded 7.3–7.4 MJ/(kg dry oat straw). The rate of biogas formation from the fermentation residues was also higher than from the corresponding pretreated but unfermented oat straw, indicating that the biogas digestion could be terminated after only 24 days. This suggests that the ethanol process acts as an additional pretreatment for the biogas process.

For the mercury, we confirm our earlier finding [Harris et al. (2003) Science301, 1203] that the methylmercury is coordinated by a single thiolate donor, which resembles cysteine, and for the selenium, we find a mixture of organic forms that resemble selenomethionine and an aliphatic selenenyl sulfide such as Cys-S-Se-Cys. We find that local chemical environments of mercury and selenium do not change upon digestion of the fish with simulated gastric fluid. We discuss the toxicological implications for humans consuming fish.

IN-SITU CHEMICAL STABILIZATION OF METALS AND RADIONUCLIDES THROUGH ENHANCED ANAEROBIC REDUCTIVE PRECIPITATION  

SciTech Connect

The objective of this NETL sponsored bench-scale study was to demonstrate the efficacy of enhanced anaerobic reductive precipitation (EARP) technology for precipitating uranium using samples from contaminated groundwater at the Fernald Closure Project (FCP) in Cincinnati, Ohio. EARP enhances the natural biological reactions in the groundwater through addition of food grade substrates (typically molasses) to drive the oxidative-reductive potential of the groundwater to a lower, more reduced state, thereby precipitating uranium from solution. In order for this in-situ technology to be successful in the long term, the precipitated uranium must not be re-dissolved at an unacceptable rate once groundwater geochemical conditions return to their pretreatment, aerobic state. The approach for this study is based on the premise that redissolution of precipitated uranium will be slowed by several mechanisms including the presence of iron sulfide precipitates and coatings, and sorption onto fresh iron oxides. A bench-scale study of the technology was performed using columns packed with site soil and subjected to a continuous flow of uranium-contaminated site groundwater (476 {micro}g/L). The ''treated'' column received a steady stream of dilute food grade molasses injected into the contaminated influent. Upon attainment of a consistently reducing environment and demonstrated removal of uranium, an iron sulfate amendment was added along with the molasses in the influent solution. After a month long period of iron addition, the treatments were halted, and uncontaminated, aerobic, unamended water was introduced to the treated column to assess rebound of uranium concentrations. In the first two months of treatment, the uranium concentration in the treated column decreased to the clean-up level (30 {micro}g/L) or below, and remained there for the remainder of the treatment period. A brief period of resolubilization of uranium was observed as the treated column returned to aerobic conditions, but the concentration later returned to below the clean-up level. Speciation analysis was conducted on soil collected from the treated column after rebound testing. The experimental results show that: (a) The mass of uranium resolubilized in more than four months of column testing was much lower than the amount precipitated. (b) The majority of the uranium was precipitated in the first few inches of the treated column. The majority of the uranium precipitated was associated with iron oxides or in other immobile/sequestered phases. It is important to contrast this result with the results reported by Bryan (2003) who shows that most of the uranium associated with contaminated aquifer solids at Fernald under the existing natural attenuation/pump and treat with reinjection conditions is carbonate bound. Carbonate bound forms are traditionally seen as fairly mobile, but may not be under a calcite/dolomite saturated condition. Fernald is currently conducting further studies to investigate the mobility of the carbonate bound forms. (c) Though reoxidation concentrations from the bench-scale column exceeded 30 {micro}g/L for a time, they later returned to below this value. Effluent concentrations from the treated column are expected to over predict full-scale concentrations for reasons discussed in depth in the text. Finally, these results must be viewed in light of the site's ongoing pump-and-treat with reinjection system. There is reason to believe that although the pump-and-treat technology is currently effectively controlling the uranium plume and reducing the groundwater concentration, it may not be able to reach the treatment standard of 30 {micro}g/L within an economical operating lifetime and then maintain that concentration without rebound. This study suggests that Enhanced Anaerobic Reductive Precipitation can change the speciation and thus reduce the mobility of uranium at the site and expedite closure.

Interspecies acetate transfer influences the extent of anaerobic benzoate degradation by syntrophic consortia  

SciTech Connect

Benzoate degradation by an anaerobic, syntrophic bacterium, strain SB, in coculture with Desulfovibrio strain G-11 reached a threshold value which depended on the amount of acetate added, and ranged from about 2.5 to 29.9 {mu}M. Increasing acetate concentrations also uncompetitively inhibited benzoate degradation. The apparent V{sub max} and K{sub m} for benzoate degradation decreased with increasing acetate concentration, but the benzoate degradation capacity (V{sub max}/K{sub m}) of cell suspensions remained comparable. The addition of an acetate-using bacterium to cocultures after the threshold was reached resulted in the degradation of benzoate to below the detection limit. Mathematical simulations showed that the benzoate threshold was not predicted by the inhibitory effect of acetate on benzoate degradation kinetics. With nitrate instead of sulfate as the terminal electron acceptor, no benzoate threshold was observed in the presence of 20 mM acetate even though the degradation capacity was lower with nitrate than with sulfate. When strain SB was grown with a hydrogen-using partner that had a 5-fold lower hydrogen utilization capacity, a 5 to 9-fold lower the benzoate degradation capacity was observed compared to SB/G-11 cocultures. The Gibb`s free energy for benzoate degradation was less negative in cell suspensions with threshold compared to those without threshold. These studies showed that the threshold was not a function of the inhibition of benzoate degradation capacity by acetate, or the toxicity of the undissociated form of acetate. Rather a critical or minimal Gibb`s free energy may exist where thermodynamic constraints preclude further benzoate degradation.

Farm-scale anaerobic storage and aerobic stability of high dry matter sorghum as a biomass feedstock  

Science Journals Connector (OSTI)

Research was conducted to determine the feasibility of using a chopped harvest and anerobic storage system to conserve mature, high dry matter (DM) sorghum intended as a cellulosic biomass feedstock for production of biofuels or bioproducts. Forage and sweet sorghum were anaerobically stored in farm-scale silo bags for over 200 days. Sorghum DM content was between 385 and 579 g kg?1. The DM lost during storage averaged 24 g kg?1 DM (range 3–48 g kg?1 DM). The additional DM lost after two- and seven-day aerobic exposure was 7 and 11 g kg?1 DM, respectively. On-harvester inoculation with a combination of homofermentative (Pediococcus pentosaceus) and heterofermentative (Lactobacillus buchneri) bacterium increased the production of both lactic and acetic acid during storage, produced lower yeast and mold populations during aerobic exposure and improved aerobic stability as quantified by temperature. Total fermentation products were less than 50 g kg?1 with an overall average of 34.9 g kg?1. Average recovery of cellulose and hemicellulose was 98% of initial mass. Anaerobic storage of chopped, inoculated, high DM, mature sorghum was shown to be a viable cellulosic biomass feedstock system.

Armed conflicts during the year including those involving Israel, Lebanon, the Palestinian Authority, and Iraq raised other issues related to the law of war. "The United States welcomed the International Committee of the Red Cross' study on the customary international law of the law of war and provided what we believe are constructive initial comments on certain aspects of methodology that raise questions about the study's conclusions. "But these issues were, of course, only one facet of the office's practice during the year. The United States dispatched to Geneva two separate large, senior-level interagency delegations to present and discuss with the UN Committee Against Torture and the Human Rights Committee U.S. implementation of its obligations under the Convention Against Torture and the International Covenant on Civil and Political Rights. . . . "The office continued to play a leading role in the development of U.S. treaty law and practice. . . . "In U.S. courts, the year saw further developments related to the applicability of the Alien Tort Statute, U.S. consular notification obligations under the Vienna Convention on Consular Relations, and the scope of the Foreign Sovereign Immunities Act, including several Supreme Court decisions on consular notification and immunities. . . ."

Effects of metals on {alpha}-amylase activity in the digestive gland of the green mussel, Perna viridis L.  

SciTech Connect

A number of digestive enzymes in the green mussel, Perna viridis L., have been reported, and {alpha}-amylase is believed to have a higher activity than the others. Small plankton, on which the green mussel feeds, may supply plenty of starch and glycogen. They may be an important source of nutrients for the green mussel and the ability of the latter to make good use of them depends mainly on the activities of amylase. The effect of heavy metals on amylase activity is also important as the ability of the mussel`s digestive gland to accumulate these metals is well known. High concentrations of heavy metals, especially lead, have been observed in the water around Singapore. The in vitro inhibition of some metals on the activities of digestive enzymes from the green mussel has been observed, but kinetic properties of the inhibition and the in vivo inhibition of the heavy metals on digestive enzymes are little understood. In the present study, in vitro inhibition of four metals (Pb, Cd, Zn and Hg) on the activity of {alpha}-amylase from the digestive gland of the green mussel will be compared. Their effects on the K{sub M} and V{sub max} values of {alpha}-amylase will also be compared. Finally, lead is either added to the food or water, to see how it affects the activity of {alpha}-amylase and how this effect acts in combination with starvation. 12 refs., 3 figs., 3 tabs.

Effect of repeated retrogradation on structural characteristics and in vitro digestibility of waxy potato starch  

Science Journals Connector (OSTI)

Abstract The effects of repeated retrogradation (RR) treatment on the structural characteristics and in vitro digestibility of waxy potato starch were investigated. The cycling times of RR ranging from 1 to 5 were designated as RR-1, RR-2, RR-3, RR-4, and RR-5, respectively. A maximum SDS content (40.41%) was obtained by RR-2 treatment with the time interval of 48 h. RR-2-treated starch product exhibited a narrower melting temperature range, a higher onset temperature and a lower melting enthalpy compared with RR-1 treatment. Compared with native starch, X-ray diffraction patterns of treated starches were altered from B-type to C-type. The variation in relative crystallinity of RR-treated starch products was consistent with that in melting enthalpy. Moreover, compared with RR-1-treated starch, a large number of cavities were observed on the surface of RR-2-treated starch product with a time interval of 48 h, whereas more smooth regions were found on the surface of RR-5-treated starch product. This study suggested that structural changes of waxy potato starch treated with different cycling times of RR significantly affected the digestibility.

HPTLC/DESI-MS Imaging of Tryptic Protein Digests Separated in Two Dimensions  

SciTech Connect

Desorption electrospray ionization mass spectrometry (DESI-MS) was demonstrated as a method to detect and identify peptides from two-dimensional separations of cytochrome c and myoglobin tryptic digests on ProteoChrom HPTLC Cellulose sheets. Data-dependent tandem mass spectra were acquired during lane scans across the TLC plates. Peptides and the corresponding proteins were identified using a protein database search software. Two-dimensional distributions of identified peptides were mapped for each separated protein digest. Sequence coverages for cytochrome c and myoglobin were 81% and 74%, respectively. These compared well to those determined using the more standard HPLC/ESI-MS/MS approach (89% and 84%, respectively). Preliminary results show that use of more sensitive instrumentation has the potential for improved detection of peptides with low Rf values and improvement in sequence coverage. However, less multiple charging and more sodiation were seen in HPTLC/DESI-MS spectra relative to HPLC/ESI-MS spectra, which can affect peptide identification by MS/MS. Methods to increase multiple charging and reduce the extent of sodiation are currently under investigation.

Digest of United States Practice in International Law 1989-1990 | Data.gov

1989-1990 1989-1990 Research Menu Data/Tools Apps Resources Let's Talk Research Alpha You are here Data.gov » Communities » Research » Data Digest of United States Practice in International Law 1989-1990 Dataset Summary Description The Office of the Legal Adviser publishes the annual Digest of United States Practice in International Law to provide the public with a historical record of the views and practice of the Government of the United States in public and private international law. In his April 2003 introduction to the 1989-1990 Digest, then Legal Adviser William H. Taft IV stated in part: "The year 1989-90 was a transitional period in international relations, as the world community continued to deal with implications of the end of the Cold War and the unsteady emergence of a new era. Many of the tensions and ambiguities of the time are reflected in the documents excerpted in this volume. For example, the Immigration Act of 1990 was adopted against the background of domestic U.S. concerns about terrorism, admission of refugees and exclusion of aliens-issues that continue to be important today. Other significant domestic law issues involved reservations to treaties (in this case, the 1948 Genocide Convention), the application of doctrines of foreign sovereign immunity (the Wallenberg Case), the interplay between sanctions and foreign assistance (e.g., Hungary, Poland, Czechoslovakia and the German Democratic Republic), and the allocation of foreign affairs authority in our federal system. "At the same time, the volume records U.S. efforts to deal effectively with the legal dimensions of very diverse issues on the international plane, including the Iraqi attack on the U.S.S. Stark, the downing of Iran Air Flight 655, the deployment of U.S. armed forces in Panama, maritime interdiction incidents, irregular rendition of criminal suspects, and the Treaty on Conventional Forces in Europe. Concerns about human rights, terrorism, and the war on drugs are indicated by the adoption of domestic legislation implementing, or relating to the implementation of, the UN Convention on Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment, the UN Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, the Montreal Protocol on Suppression of Unlawful Acts of Violence at Airports, and the IMO Convention on the Suppression of Unlawful Acts Against the Safety of Maritime Navigation (negotiated in the aftermath of the Achille Lauro incident) and its related Protocol on Fixed Platforms. . . ."

Enzymatic Digestibility of Corn Stover Fractions in Response to Fungal Pretreatment  

SciTech Connect

Corn stover fractions (leaves, cobs, and stalks) were studied for enzymatic digestibility after pretreatment with a white rot fungus, Ceriporiopsis subvermispora. Among the three fractions, leaves had the least recalcitrance to fungal pretreatment and the lignin degradation reached 45% after 30 days of pretreatment. The lignin degradation of stalks and cobs was similar but was significantly lower than that of leaves (p < 0.05). For all fractions, xylan and glucan degradation followed a pattern similar to lignin degradation, with leaves having a significantly higher percentage of degradation (p < 0.05). Hydrolytic enzyme activity also revealed that the fungus was more active in the degradation of carbohydrates in leaves. As a result of fungal pretreatment, the highest sugar yield, however, was obtained with corn cobs.

Inorganic Carbon Turnover caused by Digestion of Carbonate Sands and Metabolic Activity of Holothurians  

SciTech Connect

Recent measurements have shown that holothurians (sea cucumbers) play an important role in the cycling of CaCO3 in tropical coral reef systems through ingestion and processing of carbonate sediment. In this study inorganic additional aspects of carbon turnover were determined in laboratory incubations of Holothuria atra, H. leucospilota and Stichopus herrmanni from One Tree Reef, Great Barrier Reef. The pH values of the gut lumen ranged from 6.1 to 6.7 in animals with empty digestive tracts as opposed to 7.0 to 7.6 when digestive tracts were filled with sediment. Empty gut volume estimates for H. atra and S. herrmanni were 36 ± 4 mL and 151 ± 14 mL, respectively. Based on these measurements it is estimated that these species process 19 ± 2kg and 80 ± 7kg CaCO3 sand yr-1 per individual, respectively. The annual dissolution rates of H. atra and S. herrmanni of 6.5±1.9g and 9.6±1.4g, respectively, suggest that 0.05±0.02% and 0.1±0.02% of the CaCO3 processed through their gut annually is dissolved. During the incubations the CaCO3 dissolution was 0.07±0.01%, 0.04±0.01% and 0.21±0.05% of the fecal casts for H. atra, H. leucospilota and S. herrmanni, respectively. The CaCO3 saturation state for both aragonite and calcite minerals during laboratory incubations decreased markedly due to a greater increase in dissolved inorganic carbon (DIC) relative to total alkalinity (AT) as a result of respiration by the animals. Our results support the hypothesis that deposit feeders such as sea cucumbers play an important ecological role in the coral reef CaCO3 cycle.

Efficient degradation of lignocellulosic plant biomass without pretreatment by the 9 thermophilic anaerobe, Anaerocellum thermophilum DSM 6725  

SciTech Connect

Very few cultivated microorganisms can degrade lignocellulosic biomass without chemical pretreatment. We show here that 'Anaerocellum thermophilum' DSM 6725, an anaerobic bacterium that grows optimally at 75 C, efficiently utilizes various types of untreated plant biomass, as well as crystalline cellulose and xylan. These include hardwoods such as poplar, low-lignin grasses such as napier and Bermuda grasses, and high-lignin grasses such as switchgrass. The organism did not utilize only the soluble fraction of the untreated biomass, since insoluble plant biomass (as well as cellulose and xylan) obtained after washing at 75 C for 18 h also served as a growth substrate. The predominant end products from all growth substrates were hydrogen, acetate, and lactate. Glucose and cellobiose (on crystalline cellulose) and xylose and xylobiose (on xylan) also accumulated in the growth media during growth on the defined substrates but not during growth on the plant biomass. A. thermophilum DSM 6725 grew well on first- and second-spent biomass derived from poplar and switchgrass, where spent biomass is defined as the insoluble growth substrate recovered after the organism has reached late stationary phase. No evidence was found for the direct attachment of A. thermophilum DSM 6725 to the plant biomass. This organism differs from the closely related strain A. thermophilum Z-1320 in its ability to grow on xylose and pectin. Caldicellulosiruptor saccharolyticus DSM 8903 (optimum growth temperature, 70 C), a close relative of A. thermophilum DSM 6725, grew well on switchgrass but not on poplar, indicating a significant difference in the biomass-degrading abilities of these two otherwise very similar organisms.

Evaluation of protein fractionation and ruminal and intestinal digestibility of corn milling co-products  

Science Journals Connector (OSTI)

Novel corn milling co-products developed from technological advancements in ethanol production vary widely in chemical composition and nutrient availability. The objectives of this study were to characterize feed protein fractions and evaluate differences in rumen-undegradable protein (RUP) and its digestible fraction (dRUP), amino acid concentration, and in vitro gas production of 7 corn milling co-products. The crude protein (CP; % of dry matter) of co-products was 12.7 for germ, 26.9 for dried distillers grains plus solubles that had no heat exposure before fermentation (DDGS1), 45.4 for high-protein dried distillers grains (HPDDG), 12.7 for bran, 30.2 for wet distillers grains plus solubles (WDGS), 23.1 for wet corn gluten feed (WCGF), and 26.0 for dried distillers grains plus solubles that had heat exposure before fermentation (DDGS2). Two ruminally and duodenally fistulated Holstein steers weighing 663 ± 24 kg were used to determine RUP and dRUP with the in situ and mobile bag techniques. Samples of each feed were ruminally incubated for 16 h, and mobile bags were exposed to simulated abomasal digestion before insertion into the duodenum and subsequent collection in the feces.

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.

Nutrient leaching following land application of aerobically digested municipal sewage sludge in a northern hardwood forest  

SciTech Connect

Concentrations of selected cations and anions were determined in soil solutions from a forested site in southern New Hampshire during the first growing season after surface application of an aerobically digested, limed, liquid municipal sludge. Sludge was applied in June 1989 at 0, 3.3, 6.9, and 14.5 Mg ha{sup -1}, which corresponded to 199, 396, and 740 kg N ha{sup -1} as total Kjeldahl N (TKN). Porous, suction-cup lysimeters were used to sample soil solutions below the rooting zone ({approximately}60 cm) within subplots designed to include (untrenched) or exclude (trenched) uptake by vegetation. Following sludge application, measured solute concentrations remained low until September 1989, when NO{sub 3}, Cl, Ca, Mg, Na, and K in trenched subplots increased simultaneously to maximum values in October or November 1989, just before the soil froze for the winter. Nitrate was the dominant anion in soil solutions from trenched subplots and averaged in excess of 0.71 mmol L{sup -1} (10 mg L{sup -1} NO{sub 3}-N) at all loading rates. Highest concentrations of NO{sub 3} occurred on subplots with the highest sludge application rates. In the entrenched areas, NO{sub 3} concentrations rarely exceeded 0.001 mmol L{sup -1}; Cl increased in treated areas and was the dominant anion by the end of the season. Soil solution NH{sub 4}, PO{sub 4}, SO{sub 4} K, and pH did not change significantly for any sludge application rate. Comparison of results from trenched and untrenched areas suggests that, at application rates of up to 14.5 Mg ha{sup -1 }(799 kg TKN ha{sup -1}), a combination of physical, chemical, and biological factors (most likely plant uptake) limited the movement of sludge or sludge-derived constituents from the sites of application. 37 refs., 8 figs., 3 tabs.

Sequential extraction of metals from mixed and digested sludge from aerobic WWTPs sited in the south of Spain  

SciTech Connect

The content of heavy metals is the major limitation to the application of sewage sludge in soil. However, assessment of the pollution by total metal determination does not reveal the true environmental impact. It is necessary to apply sequential extraction techniques to obtain suitable information about their bioavailability or toxicity. In this paper, sequential extraction of metals from sludge before and after aerobic digestion was applied to sludge from five WWTPs in southern Spain to obtain information about the influence of the digestion treatment in the concentration of the metals. The percentage of each metal as residual, oxidizable, reducible and exchangeable form was calculated. For this purpose, sludge samples were collected from two different points of the plants, namely, sludge from the mixture (primary and secondary sludge) tank (mixed sludge, MS) and the digested-dewatered sludge (final sludge, FS). Heavy metals, Al, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Ti and Zn, were extracted following the sequential extraction scheme proposed by the Standards, Measurements and Testing Programme of the European Commission and determined by inductively-coupled plasma atomic emission spectrometry. The total concentration of heavy metals in the measured sludge samples did not exceed the limits set out by European legislation and were mainly associated with the two less-available fractions (27-28% as oxidizable metal and 44-50% as residual metal). However, metals as Co (64% in MS and 52% in FS samples), Mn (82% in MS and 79% in FS), Ni (32% in MS and 26% in FS) and Zn (79% in MS and 62% in FS) were present at important percentages as available forms. In addition, results showed a clear increase of the concentration of metals after sludge treatment in the proportion of two less-available fractions (oxidizable and residual metal)

Nitrogen utilization, nutrient digestibility, and excretion of purine derivatives in dairy cattle consuming rations containing corn milling co-products  

Science Journals Connector (OSTI)

The objectives of this experiment were to determine the effects of feeding a combination of modified wet distillers grains with solubles (WDGS) and wet corn gluten feed (WCGF) on nutrient digestion, purine derivative excretion, and N utilization. Multiparous (n = 20) and primiparous (n = 20) cows were arranged in a replicated 5 × 5 Latin square with 21-d periods. Animals were fed one of 5 treatment diets during each period: 1) 0% co-products (control); 2) 15% WDGS (15WDGS); 3) 15% WCGF (15WCGF); 4) 7.5% WDGS and 7.5% WCGF (15MIX); and 5) 15% WDGS and 15% WCGF (30MIX; dry matter basis). A portion of forages, corn, and soy-based protein was replaced with WDGS, or WCGF, or both. Dry matter intake was greater for 15WDGS (25.1 kg/d) and 30MIX (25.5 kg/d) than for control (22.4 kg/d), 15WCGF (23.2 kg/d), or 15MIX (23.5 kg/d). Dry matter digestibility was greatest for 15WCGF and 30MIX (63.6 and 64.1%, respectively) and least for 15WDGS (59.8%), and neutral detergent fiber and N digestibility were greatest for 30MIX (50.7 and 68.6%, respectively) and lowest for 15WDGS (41.3 and 61.5%, respectively). Excretion of purine derivatives in urine was greater for co-product treatment diets than for control. Fecal N was greatest for 15WDGS compared with other treatment diets (311.0 vs. 263.3 g/d), whereas urinary N was greatest for 30MIX (330.0 g/d), intermediate for 15WCGF and 15MIX (319.3 and 320.5 g/d, respectively), and lowest for control and 15WDGS (308.5 and 312.2 g/d, respectively). Manure N (fecal + urinary N) was greatest for 15WDGS, intermediate for 15MIX and 30MIX, and lowest for control and 15WCGF. Treatment diets did not differ in 4% fat-corrected milk production. Compared with the ration containing WDGS, the ration with a 30% mixture of WDGS and WCGF improved nutrient digestibility and N utilization with reduced manure N excretion and increased N retention. Thus, it appears feeding WDGS and WCGF in combination reduces some of the negative effects of feeding WDGS alone.
