Fermentation of corn-cob hydrolyzates with butanol bacteria

Abstract

Experiments to produce BuOH from hydrolyzates of corn cobs and sunflower husks after addition to beet molasses are described. Corn cobs were heated at atmosphere pressure at 100/sup 0/ for 3 to 8 hourse at 4.1% initial H/sub 2/SO/sub 4/ concentration, for sunflower hulls 120/sup 0/ for 20 minutes was used. The concentration,of solids was 25 and 33%, respectively. The hydrolyzate was neutralized with lime to pH 6.7 to 6.9 and (NH/sub 4/)/sub 2/DO/sub 4/ and superphosphate were added. The best yields were obtained if the mash contained 40 to 60% hydrolyzate and 60 to 40% molasses (on sugar basis). The sugar content of the mashes was 3.7%. Yields in total organic solvents and BuOH were 40% and 27%, respectively, calculated on the initial sugar in the mash. Fermentation time was 2 to 3 days. The strain used in probably a variety of Clostridium butylicum.
