Cellulases and xylanase-producing Aspergillus niger KK2, produced enzymes and solid materials thereof

摘要

PURPOSE: Cellulase and xylanase-producing Aspergillus niger KK2, and a process for preparing enzymes and solid culture products using the same microorganism are provided, thereby cheaply producing cellulase and xylanase in higher yield. CONSTITUTION: Cellulase and xylanase-producing Aspergillus niger KK2(KFCC-11285) is provided. A process for preparing enzymes comprises the steps of: seed culturing the cellulase and xylanase-producing Aspergillus niger KK2(KFCC-11285); inoculating the seed cultured medium into a broth or solid medium;culturing the broth or solid medium; and recovering the cultured medium, wherein the enzyme is selected from FPase(filter paper decomposing enzyme), CMCase(carboxymethylcellulose F decomposing enzyme), beta-glucosidase and beta-xylanase; the broth medium contains the combination of rice-straw and wheat bran, and the solid medium contains single or combination of rice-straw and wheat bran; and the solid medium has the water content of 50 to 80%.
