nitrogenase
PhysiologyInfluence of Energy and Electron Availability on In Vivo Methane and Hydrogen Production by a Variant Molybdenum NitrogenaseA variant form of Mo nitrogenase catalyzes the conversion of CO2 and protons to the biofuels CH4 and H2. A constant supply of electrons and ATP is needed to drive these reduction reactions. The bacterium R. palustris generates ATP from light and has a versatile metabolism that makes it ideal for manipulating electron availability...
BiotechnologyIntroduction of Glyoxylate Bypass Increases Hydrogen Gas Yield from Acetate and l-Glutamate in Rhodobacter sphaeroidesAs an alternative to fossil fuel, H2 is a promising renewable energy source. Although photofermentative H2 production from acetate is key to developing an efficient process of biohydrogen production from biomass-derived sugars, H2 yields from acetate and l-glutamate by R. sphaeroides have been reported to be low...
