摘要
FIELD: biotechnology, microbiology.;SUBSTANCE: invention relates to producing ethyl alcohol or fodder for monogastral animals. The polyenzyme product with glucoamylase, proteolytic and xylanase activities is prepared by fermentation of wheat bran using microorganism Aspergillus niger. Indicated glucoamylase, proteolytic and xylanase activities have the following minimal values: glucoamylase activity - at least 100 U/g of dry matter; proteolytic activity - at least 100 U/g of dry matter; xylanase activity - at least 100 U/g of dry matter under condition that glucoamylase activity has to be at least 750 U/g of dry matter and/or xylanase activity has to be at least 300 U/g of dry matter. Invention provides enhancing the soluble nitrogen content in wort after saccharification, reducing viscosity and effectiveness in using.;EFFECT: improved preparing method, valuable properties of hydrolyzed bran.;14 cl, 10 tbl, 7 ex
