Corn fiber is a byproduct of the wet milling industry and acts as a low cost feedstock in fuel ethanol manufacture. Experiments evaluated pretreatments, including hot water, alkali, and dilute acid pretreatments, as well as enzymatic saccharification, for the conversion of corn fiber starch, cellulose, and hemicellulose to fermentable sugars. Commercially available hemicellulase products do not effectively hydrolyze corn fiber xylan to simple sugars because of its complex structure. Researchers developed a method involving dilute acid pretreatment of corn fiber and saccharification with commercially available cellulase and beta-glucosidase. Actual yield of monomeric sugars ranged from 85-100 percent of the theoretical yield. Abstract.
