| [mechanisms of bioelectricity generation in enterobacter aerogenes-based microbial fuel cells]. | microbial fuel cells (mfcs) using hydrogen-producing bacteria (hpb) could utilize a large number of substrates to generate power. however, the coulombic efficiency is limited by the fact that only suspended cells are used as biocatalyst in anodic medium. mfcs using fe (iii)-reducing bacteria have high energy recovery efficiency, but can only utilize some simple organic matters. in this study, enterobacter aerogenes xm02, a hydrogen-producing strain with fe(iii)-reducing activity, was selected as ... | 2009 | 19545032 |
| expression of nad+-dependent formate dehydrogenase in enterobacter aerogenes and its involvement in anaerobic metabolism and h2 production. | an expression system for nad(+)-dependent formate dehydrogenase gene (fdh1), from candida boidinii, was constructed and cloned into enterobacter aerogenes iam1183. with the fdh1 expression, the total h(2) yield was attributed to a decrease in activity of the lactate pathway and an increase of the formate pathway flux due to the nadh regeneration. analysis of the redox state balance and ethanol-to-acetate ratio in the fdhl-expressed strain showed that increased reducing power arose from the recon ... | 2009 | 19533026 |
