Cow manure represents a surplus waste in agricultural food sectors, which requires proper disposal. Anaerobic digestion, this regard, has raised global interest owing to its apparent environmental benefits, including simultaneous diminishment and renewable energy generation. However, dedicated intensifications are necessary promote the degradation of recalcitrant lignocellulosic components cow ...

The etiologic agent of Lyme disease, Borrelia burgdorferi, must adapt to the distinct environments of its arthropod vector and mammalian host during its complex life cycle. B. burgdorferi alters gene expression and protein synthesis in response to temperature, pH, and other uncharacterized environmental factors. The hypothesis tested in this study is that dissolved gases, including CO(2), serve...

a thermophilic anaerobic contact reactor for the treatment of potato-processing wastewaterswas designed as a continuous-flow, completely-mixed homogeneous system. the reactor was operated at ten different organic loading rates ranging from 0.84 g cod/l·d to 7.00 g cod/l·d for a duration of approximately 250 days. the fundamental way to maintain optimum operating conditions of anaerobic digestio...

The effect of carbon monoxide on the respiration of animal cells and aerobic bacteria (10), and on anaerobic butyric acid fermentation (6), has shown that the ferments which act as catalysts in these energy-yielding cellular processes are compounds of heavy metals: for carbon monoxide reacts at low temperatures only with heavy metals, and respiration as well as anaerobic butyric acid fermentati...

Fossil fuel depletion, climate change, and increased global energy demands are the driving forces to find alternative sources of energy. Marine-based biorefinery has been recently discussed as a promising route mitigate environmental challenges, enhance recovery, provide potential source for value-added products. Anaerobic digestion is technology that can convert organic compounds marine ecosys...

The purpose of this research is to experimentally evaluate the anaerobic co-digestion in city Guaranda slaughterhouse residues (RM) with straw from agriculture, such as amaranth (AM), quinoa (QU) and wheat (TR), reduce discharges prevent contamination city. study was carried out on a laboratory scale 311-ml biodigesters under mesophilic conditions 37 °C. In addition, sewage sludge used inoculum...

Carboxydothermus hydrogenoformans is a thermophilic strictly anaerobic bacterium that catalyses the water gas shift reaction, the conversion of carbon monoxide with water to molecular hydrogen and carbon dioxide. The thermodynamically favorable growth temperature, compared to existing industrial catalytic processes, makes this organism an interesting alternative for production of cheap hydrogen...

Spent livestock bedding is a valuable resource for the production of green energy (methane) in rural areas. Comparison and evaluation batch anaerobic digestion co-digestion different mixtures goat straw (SGSB) cheese whey were carried out. Biochemical methane potential (BMP) tests 100% SGSB, 95% SGSB-5% whey, 90% SGSB-10% 85% SGSB-15% found to be 423 ± 7, 354 9, 371 2, 293 1, 274 2 mL CH4 g?1 V...
