Effect of gas feed composition (CO/H2/N2) on steady-state bubble column performance of the C. autoethanogenum-E. rectale coculture system. (a) C. autoethanogenum and E. rectale biomass concentrations exiting the column; (b) gas-phase CO concentration as a function of column position; (c) acetate and ethanol concentrations exiting the column; (d) acetate secretion rates for C. autoethanogenum and uptake rates for E. rectale; (e) E. rectale growth rates as a function of column position ; (f) butyrate concentrations and mass productions based on the liquid stream exiting the column.
