Determination of the stoichiometry of electron transfer in the two sulfur reductase reactions. The relative biomass yield ratios of ethanol to hydrogen were obtained from experimental data of P. carbinolicus grown in batch culture with ethanol or hydrogen as electron donor and Fe(III) oxide or Fe(III)-NTA as electron acceptor [17], and were compared to simulation results varying the stoichiometry of the electron transfer in the two sulfur reductase reactions. The red arrow indicates a close match between experimental and simulation results.
