A system capable of biocatalytic conversion of distributed sources of single carbon gases such as carbon monoxide into hydrocarbons can be highly beneficial for developing commercially viable biotechnology applications in alternative energy. Several anaerobic bacterial strains can be used for such conversion. The anaerobic carbon monoxide-fixing bacteria Clostridium ljungdahlii OTA1 is a model ...

although several methods have been developed to make gamma-aminobutyric acid (gaba) accumulate in tea, the active ingredients and health benefits vary widely depending on the manufacturing process of tea products. in this study, the levels of bioactive compounds and antioxidant activity in tea leaves given the continuous anaerobic condition were investigated. gaba and other free amino acids suc...

Fluxes of greenhouse gases to the atmosphere are heavily influenced by microbiological activity. Microbial enzymes involved in the production and consumption of greenhouse gases often contain metal cofactors. While extensive research has examined the influence of Fe bioavailability on microbial CO(2) cycling, fewer studies have explored metal requirements for microbial production and consumptio...

In the present experimental study, anaerobic co-digestion of wheat straw with textile industry wastewater (TIWW) was evaluated for biogas production. Anaerobic digestion systems were operated at ambient temperature (28-30 ºC) 20 days. Five different ratios distilled water added to inoculated cow dung operating in five digesters. Time-rate derivative models, including Gompertz’s model and its re...

Glycolytic activity of rat peritoneal mast cells has been measured by the Cartesian ampulla diver technique. The rates of anaerobic glycolysis, expressed as CO(2) expelled from a bicarbonate medium, are 1.70 x 10(-6) microl and 1.43 x 10(-6) microl per cell per hour with and without glucose, respectively. The aerobic glycolysis rate in the presence of glucose, assuming the respiratory quotient ...

Simultaneous removal of NO(x) and SO2 from exhausted gas were investigated by studying co-culture of sulfate reducing bacteria and anaerobic denitrifying bacteria, separated from landfill leachate. When H2S, generated by sulfate reducing bacteria was chosen as the sole electron donor for anaerobic denitrifying bacteria, the co-culture system demonstrated a faster NO removal rate, higher stabili...

background : in this study, the inhibitory effect of ethylene dichloride (edc) on biodegradation was investigated using the specific methanogenic activity (sma) test of anaerobic biomass. methods: in the present study, 40 sma tests were performed using 120-ml vials in batch mode. substrate, biomass, and biogas occupied 66%, 17%, and 17% (v/v) of the volume of each vial, respectively. the durati...
