Abstract
A process provides high ethanol productivity levels during fermentation of a CO-containing substrate. The process controls CO-substrate feed rates and cell density to avoid culture upset and CO inhibition. The process includes fermenting a CO-containing gaseous substrate to obtain a target cell density and a target CO feed rate, and then periodically reducing and increasing the CO feed rate.
