Proposed model of the metabolic flux and carbon and electron balance of the three member community. * Values given are in moles. ** Circled electron equivalents could be hydrogen, interspecies electron transfer, or ethanol. See text for details. *** N-moles of biomass determined according to C4H7O1.5N + minerals, 104 gMW (Harris and Adams, 1979). Note: The underlined biomass value (0.1) was used for calculations in Additional File 1.
