Using a U-tube MFC approach developed earlier as a part of this project, we isolated a pure culture classified Enterobactcr cloacae based on 16S rDNA sequencing and physiological and biochemical characterization. This strain was remarkable because it was able to produce electricity in a microbial fuel cell from the degradation of cellulose. This is the first time that a bacterium has been shown to be able to accomplish both of these tasks. We examined the communities that developed in MFCs based on electrode surface material and the effects of light on the community. We have also shown that Rhodopseudomonas palustris strain DX-l, a strain previously isolated as a part of this project, was capable of being used in a microbial electrolysis cell for the biologically-driven electrochemical production of hydrogen gas.
