We report on the hydrogen production properties of the unicellular, diazotrophic cyanobacterium Cyanothece sp. strain ATCC 51142. This organism has a versatile metabolism and can grow in the presence or absence of combined nitrogen and can grow photosynthetically or mixotrophically and heterotrophically in the presence of glycerol. The strain produces a bidirectional hydrogenase (encoded by the...

This study investigates the anaerobic treatability of reactive Red2 in an anaerobic/aerobic sequential process. Laboratory scale anaerobic baffled reactor and fixed activated sludge reactor were operated at different organic loadings and hydraulic retention times. The effects of shock dye concentration on the chemical oxygen demand and color removal efficiencies were investigated in the anaerob...

This study investigates the anaerobic treatability of Acid orange dye in an anaerobic/aerobic sequential process. Laboratory scale anaerobic baffled reactor and fixed activated sludge reactor were operated at different organic loadings and hydraulic retention times. The effects of shock dye concentration on the chemical oxygen demand and color removal efficiencies were investigated in the anaer...

This work investigates the impact of sugar-to-protein (STP) ratio on outcome their anaerobic cofermentation in terms substrate conversion and product selectivity. For this purpose, a continuous...

background petroleum reservoirs have long been known as the hosts of extremophilic microorganisms. some of these microorganisms are known for their potential biotechnological applications, particularly production of extra and intracellular polymers and enzymes. objectives here, 14 petroleum liquid samples from southern iranian oil reservoirs were screened for presence of biosurfactant‐producing...
