SUMMARY: Chlorella cultures were grown in a tubular loop reactor which facilitated both irradiation of the culture and gas mixing compared with a conventional stirred vessel with vortex aeration. Measurements of the inhibition of maximum specific growth rate (proportional to photosynthetic rate) in the tubular reactor showed that CO behaves as a typical inhibitory substrate at partial pressures (P) up to 0.6 atm. The P for 50% reduction in maximum specific growth rate was 0.36 atm. At 0.6 atm there was a discontinuity in the inhibitory effect with a sharp increase in the inhibitory effect at higher P values. Cultures rapidly adjusted to step changes in the P up to 0.6 atm. At a P of 1 atm inhibition was complete but the inhibitory effect was readily reversed.
