Multi-enzyme product with glucoamylase, proteolytic and xylanase activities and method for producing same by solid state fermentation of wheat bran with Aspergillus niger



Multi-enzyme product with glucoamylase, proteolytic and xylanase activities and method for producing same by solid state fermentation of wheat bran with Aspergillus niger



Official Gazette of the United States Patent & Trademark Office Patents 1277(4), Dec 23



The invention concerns a multi-enzyme product with glucoamylase, proteolytic and xylanase activities, characterized in that it consists of wheat bran fermented with an Aspergillus niger strain, said enzymatic glucoamylase, proteolytic and xylanase activities being present in the following minimum values: glucoamylase activity: at least 100 UG per gram of dry matter; proteolytic activity: at least 100 UP per gram of dry matter; xylanase activity: at least 100 UX per gram of dry matter, provided that at least one of the following conditions is satisfied: the gluycoamylase activity is at least 750 UG per gram of dry matter, or the xylanase is at least 300 UX per gram of dry matter. The invention is useful for producing ethanol or monogastric animal feed.
