Abstract

Bacillus sp. strain TW-1, grown on corn hull as a carbon source under limited oxygen conditionproduced xylanolytic enzyme (xylanase, β-xylosidase and arabinofuranosidase), cellulolytic enzyme(avicelase, carboxymethyl cellulase and β-glucosidase) and mannanase. These enzymes could hydrolyzexylan and cellulose in corn hull to xylose, xylobiose, and oligosaccharides under batch fermentation.Moreover, ethanol and acetic acid were also detected in the medium. Crude xylanolytic and cellulolyticenzymes produced by Bacillus sp. strain TW-1 could hydrolyze agricultural residues. The result showedthat the crude enzyme could be hydrolyzed corn hull better than corn cob, rice bran, sugarcane bagasseand rice straw respectively.
