Hydrolysis Profile of Oil Palm Empty Fruit Bunch by An Extracellular Enzyme From Aspergillus niger

Abstract

Large quantities of oil palm empty fruit bunch (OPEFB) biomass with low economic value were released during oil palm production. This biomass components are cellulose (41-46%), hemicellulose (25-34%), lignin (27–32%), and C/N ratio 70-100 so that in nature OPEFB decomposition takes much time. To overcome this problem microbial utilization is needed. In this research, an extracellular enzyme from Aspergillus niger was used to hydrolyze OPEFB and gave the rate hydrolysis at 1.5% (756ug/ml) for 6 hours respectively. It was estimated by Gas Chromatograph (GC) analysis as alditol acetate proved that the main sugar in hydrolysate as monosaccharide was glucose with the concentration 74.2%. Suggested, much cellulase was released by A. niger during solid stated fermentation.
