摘要
A process is provided that is effective for reducing CO2 emissions, enhancing STY and/or increasing cell density. The process allows for utilization of syngas from different sources by controlling concentration levels of CO, CO2 and H2 in syngas provided to the fermentation and by controlling relative concentrations of CO, CO2 and H2 in the syngas provided to the fermentation. The process includes providing syngas to a first fermentation zone and fermenting the syngas. If the first fermentation zone off-gas includes about 4 mole % or more CO, then at least a portion of the first fermentor off-gas is provided to one or more subsequent fermentation zones.
