Abstract: One goal of the syngas fermentation is the shift from acid to alcohol production. Continuously gassed batch processes in a controlled stirred-tank reactor with Clostridium ragsdalei showed that lowering the pH to pH 5.5 as well as the process temperature to 32 °C was beneficial for alcohol production (ethanol and 2,3-butandiol). The combination with an appropriate sulfide feed resulted in a substantial shift from acid to alcohol production, leading to an alcohol to acetate mass ratio of > 17.
