Patent

CA 2361264

The invention concerns a multi-enzyme product with glucoamylase, proteolytic and xylanase activities, characterised 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 - the xylanase is at least 300 UX per gram of dry matter. The invention is useful for producing ethanol or monogastric animal feed.

Produit multienzymatique présentant des activités glucoamylasique, protéolytique et xylanasique, caractérisé en ce qu'il est constitué de son de blé fermenté avec une souche d'Aspergillus niger, lesdites activités enzymatiques glucoamylasique, protéolytique et xynalasique étant présentes aux valeurs minimales suivantes: glucoamylasique: au moins 100 UG par gramme de matière sèche; protéolytique: au moins 100 UP par gramme de matière sèche; xylanasique: au moins 100 UX par gramme de matière sèche; avec la condition que l'activité glucoamylasique soit d'au moins 750 UG par gramme de matière sèche et/ou l'activité xylanasique soit d'au moins 300 UX par gramme de matière sèche. Utilisation dans la production d'éthanol ou d'aliments pour animaux monogastriques.
