Summary
Biomass production of Zymomonas mobilis in continuous cultivation on synthetic or complex glucose media was increased up to 100% when CO2 partial pressure was reduced from 1,460 to 95 mbar at high dilution rates. Biomass yield increased and specific glucose uptake and ethanol production rates decreased approximately 6% when pCO2 was lowered from 1,160 to 95 mbar. Product yield was not affected by pCO2. Long time adaptation superimposing these effects was considered.
