Abstract
Issue Title: Special Issue: Biorefinery of biomass for bioenergy Using low-cost raw material is an effective approach for reducing the cost of cellulolytic enzymes. The farmland waste corncob was found in this study to be the best carbon source for the production of β-glucosidase by Aspergillus niger. The maximum yield of β-glucosidase activity was 48.7 IU ml^sup -1^ by using 50 gl^sup -1^ of corncob powder as the substrate. It was found that the water-soluble components of the corncob could increase β-glucosidase production significantly only when mixed with Avicel or wheat bran. The soluble components could not enhance the biomass and β-glucosidase production when used alone. On the other hand, the water-insoluble components of the corncob still produced high level of β-glucosidase (30 IU ml^sup -1^) although lower than that of using whole corncob. The results suggested that the water-insoluble components of corncob were beneficial for β-glucosidase production. It was further demonstrated that the xylan in the water-insoluble parts of corncob was the important factor in producing β-glucosidase by A. niger. [PUBLICATION ABSTRACT]
