The production of electricity from renewable biomass can contribute to an array of renewable energy production . Since there are no known cellulolytic exoelectrogens, the conversion of cellulosic biomass to electricity requires a unique syntrophic microbial community that uses not only an insoluble electron acceptor (anode) but also an insoluble electron donor (cellulose). Our work presented the results of cellulose-fed microbial fuel cells using a defined binary culture of cellulolytic ( Clostridium cellulolyticum) and exoelectrogenic (Geobacter sulfurreducens ) bacteria and a mixed culture derived from wastewater. The results showed a successful conversion from cellulose to electricity in microbial fuel cells.
