Microbial insights of enhanced anaerobic conversion of syngas into volatile fatty acids by co-fermentation with carbohydrate-rich synthetic wastewater

摘要

Performance in syngas–glucose co-fermentation bottles: syngas consumption at steady state, produced VFA in the effluent at steady state, degradation of glucose in 24 h and syngas consumption rate in 24 h. The steady state was defined by a sustained VFAs production and syngas consumption within ± 5% deviation. The CO/H conversion efficiencies calculated with the CO/H consumptions dividing by the total volume of CO/H in bottles. Ethanol production was insignificant (
