Bacillus sp. strain TW-1, grown in corn hull as carbon source under an anaerobic condition could produce xylanolytic and cellulolytic enzymes such as xylanase, avicelase, mannanase, carboxymethyl cellulase (CMCase), beta-xylosidase, beta-glucosidase, and arabinofuranosidase. These enzymes could be hydrolyse xylan and cellulose present in agricultural wastes. The hydrolysis of corn hull was better than those of corn cob, rice bran, sugarcane bagasse, and rice straw. The products of this hydrolysis were xylose, xylobiose, and other oligosaccharides. Moreover ethanol and acetic acids were found in culture supernatant of Bacillus sp. strain TW-1, grown in corn hull as a sole carbon source under limited oxygen.
