Fig. 1From: The effects of CO2 and H2 on CO metabolism by pure and mixed microbial culturesFermentation of (a–d) CO, and (e–h) CO: CO2: H2 by the mixed and pure CO-consuming cultures. Panels d and h show that no CO, H2, or CO2 was abiotically consumed. The initial CO partial pressure was 30.4 kPa. The data are averages of triplicates; error bars indicate one standard deviationBack to article page
