Co-cultivation under excess CO conditions. Shaking was applied after 4 days (red vertical line). a Acid concentration profile. b Alcohol concentration profile. c Partial gas pressures of CO, CO2, and H2. d Estimated total concentration of products formed, approximated by a Gompertz equation. e Total estimated volumetric production rates displayed as the derivative of the Gompertz equation. f Estimated net volumetric production rates after compensation of product formation and consumption according to Eqs. 3 and 4. Solid and open circle symbols represent left and right y-axis, respectively
