Steady-state gas uptake and production in gas-fermenting C. autoethanogenum chemostats. Data for high biomass concentration chemostats (~ 1.4 gDCW/L) are shown and represented as the average ± standard deviation between biological duplicates (syngas) and quadruplicates (CO and high-H₂ CO). Syngas data from our previous work [28]. DCW dry cell weight, \(q_{{{\text{CO}}_{2} }}\) specific CO₂ production rate, q_CO and \(q_{{{\text{H}}_{2} }}\) specific CO and H₂ uptake rates, respectively
