NOVELTY - An isolated organic acid-consuming thermophilic electricigenic bacterium, is new.    USE - The bacterium, processes, and apparatus are useful for generating ethanol, electricity, and hydrogen (all claimed).    ADVANTAGE - The present invention provides enhanced bioethanol and/or hydrogen production from plant waste. The current invention results in higher yields of ethanol, hydrogen and/or electricity. More energy will be extracted from the plant waste (cellulose) for less cost with a better yield than what previously could be done with corn or cellulose.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are:    (1) a process for generating electricity by supplying a microbial catalyst and a fuel source to a microbial fuel cell under thermophilic conditions, where the microbial catalyst consumes the fuel source and generates electricity;    (2) a process of generating ethanol and electricity by (A) supplying a microbial catalyst and a fuel source to a fermentation vessel in operable relation with a microbial fuel cell, where the microbial catalyst has a cellulolytic activity, an ethanologenic activity, and an electricigenic activity, and where the fuel source is consumed and ethanol and electricity are generated, or (B) supplying a microbial catalyst having ethanologenic activity and a fuel source to a first fermentation vessel, where a spent fuel source is generated, and supplying the spent fuel source and a second microbial catalyst having a cellulolytic activity and an electricigenic activity to a second fermentation vessel, where the second fermentation vessel is in operable relation with a microbial fuel cell, where the spent fuel source is consumed, where ethanol and electricity are generated;    (3) a process of generating hydrogen by supplying a microbial catalyst and a fuel source to a bio-electrochemically assisted microbial reactor (BEAMR) system, where the microbial catalyst consumes the fuel source and generates hydrogen, where the BEAMR system is under thermophilic conditions;    (4) a process of generating ethanol and hydrogen by supplying a microbial catalyst and a fuel source to a BEAMR system, where the microbial catalyst has a cellulolytic activity, an ethanologenic activity, and an electricigenic activity, where the fuel source is consumed and ethanol and hydrogen are generated;    (5) an apparatus for generating ethanol and electricity comprising a fermentation vessel in operable relation with a microbial fuel cell; and    (6) an apparatus for generating ethanol and hydrogen comprising a chamber, a fuel source, a microbial catalyst, and a power source in connective relation to an anode and a cathode, where the anode and the cathode are located within the chamber.
