Complex enzyme composition for degradating non starch polysaccharide and method for preparation thereof

摘要

PURPOSE: A complex enzyme composition for the non-starch polysaccharide degradation, and a producing method thereof are provided to effectively decompose non-decomposable polysaccharide. CONSTITUTION: A producing method of a complex enzyme composition for the non-starch polysaccharide degradation comprises the following steps: culturing strains of aspergillus oryzae GB-N1 aspergillus niger GB-X2; culturing starter culture liquid using a forced circulation solid fermentation method by controlling the moisture content; and collecting cultured materials to obtain enzymes. The enzymes are protease, amylase, alpha-galactosidase, xylanase, and cellulase. The starter culture liquid is cultured in a culture medium including wheat bran. The moisture content of the complex enzyme composition is controlled in 45-50%.
