Autotrophic syngas conversion with a co‐culture of C. carboxidivorans and C. kluyveri (black) and a mono‐culture of C. carboxidivorans (white) in batch‐operated stirred‐tank bioreactors with continuous gassing with an initial CO partial pressures p _CO,in = 100 mbar.

A. CDW concentration of C. kluyveri.

B. CDW concentrations of C. carboxidivorans.

C. Acetate concentrations.

D. Ethanol concentrations.

E. Butyrate concentrations.

F. Butanol concentrations.

G. Hexanoate concentrations.

H. Hexanol concentrations. Error bars indicate the deviation of the minimum and maximum value from the mean value of two independent batch processes. (T = 37°C; pH = 6.0; P V ⁻¹ = 11.7 W l⁻¹; F _gas = 5 l h⁻¹ (10:20 CO:CO₂)).
