A synthetic syngas mixture (CO/CO2/H2/N2: 52/21/24/3) and 100% CO were used as the carbon and energy source in chemically defined mineral medium (without yeast extract and vitamins). a, b Biomass (OD600), acetate formation, and maximum specific growth rate on syngas (a) and CO (b). c, d.Gas uptake (positive) and production (negative) rates on syngas (c) and CO (d). Change of gas uptake/production rates at the end of the experiment due to flushing with N2. The maximum specific growth rate µmax ( ± standard deviation) was calculated from the exponential growth phase of each culture (6−13 h for syngas and 13−19 h for CO). Source data are provided as a Source Data file.
