Claim:
1. A microbial fuel cell comprising: an anode electrode contained in an anode chamber, a cathode electrode contained in a cathode chamber, and a reference electrode contained in the anode chamber or the cathode chamber, wherein the anode electrode, the cathode electrode and the reference electrode are electronically connected to each other; a first biocatalyst located in the anode chamber and comprising a mesophilic consolidated bioprocessing organism configured to hydrolyze and/or ferment biomass to produce one or more fermentation waste byproducts, wherein the mesophilic consolidated bioprocessing organism is also configured to anaerobically co-ferment six- and five-carbon sugars and comprises a second biocatalyst located in the anode chamber and comprising an alcohol-tolerant electricigen cultured at a temperature not greater than 40° C. and configured to convert substantially all of the fermentation waste byproducts to electricity by transferring substantially all electrons present therein to the anode electrode, wherein the fermentation waste byproducts converted to electricity include acetate, formate, and/or lactate.
