Abstract
An electrochemical cell comprising an anode electrode, a cathode electrode and a reference electrode electronically connected to each other; a first biocatalyst comprising a consolidated bioprocessing organism (e.g., a cellulomonad or clostridium or related strains, such as Cellulomonas uda (C. uda), Clostridium lentocellum (C. lentocellum), Acetivibrio celluloyticus (A. cellulolyticus) Clostridium cellobioparum (C. cellobioparum), alcohol-tolerant C. cellobioparum, alcohol-tolerant C. uda, and combinations thereof) capable of fermenting biomass (e.g., cellulosic biomass or glycerin-containing biomass) to produce a fermentation byproduct; and a second biocatalyst comprising an electricigen (e.g., Geobacter sulfurreducens) capable of transferring substantially all the electrons in the fermentation byproduct (e.g., hydrogen, one or more organic acids, or a combination thereof) to the anode electrode to produce electricity is disclosed. Systems and methods related thereto are also disclosing a consolidated bioprocessing organism.
