Application of Soybean Meal on Butanol Production from Corncob Hydrolysate by Clostridium acetobutylicum CH012

Abstract:

Soybean meal, the residue of soybean extract oil, mainly consists of protein. It was used as the only additive of corncob hydrolysate to produce acetone, butanol and ethanol with C. acetobutylium CH012. Because of inhibitors existing in corncob acid hydrolysate, butanol concentration was obtained only 6.61gL-1 by fermentation. Acetone concentration was 5.1gL-1 which was higher than a normal ratio of starch and molasses ABE fermentation. ABE fermentation of corncob enzymatic hydrolysate resulted in a productivity of 0.28gL-1h-1 and a solvent yield of 0.30. It was suggested that soybean meal could be a potential economical protein provider for ABE fermentation. Furthermore, for all experiments, cultivate including strain inoculum developed and batch fermentation was done in calorstat which would be beneficial to apply in the hydrolyate ABE fermentation industry.
