Schematic representation of the metabolite flow in a continuous bioreactor operated with a methanogenic coculture system. Acetate production is assumed to take place directly from CO only, by the hydrogenogen. In contrast to CO, H2 and CH4, CO2 is also removed in significant amounts via the liquid outflow (HCO3/CO2). Calculations were performed using pH 7.2.
