Abstract
Abstract Crude hemicellulase by novel mycoparasitic Trichoderma asperellum (GenBank accession nos. T. asperellum could withstand up to 50% selected hydrolytic and fermentation inhibitors. Supplement of hemicellulase crude to Celluclast 1.5 L at 1FPU:5U enhanced the hydrolysis of alkaline-treated OPEFB biomass achieving a 91.7% saccharification yield, higher than 77.9% yield or 12.2% yield when no hemicellulase was used or used without addition of cellulase respectively. The high saccharification yield, which has not been attained in any previous report on OPEFB, demonstrates the potential of T. asperellum for the development of efficient enzyme system for lignocellulosic bio-conversion. As far as we know, this is the first report on enhancement of lignocellulosic co-hydrolysis through synergism of hemicellulase crude by T. asperellum and commercial cellulase.
