Abstract

A xylanase composition and a method for manufacturing the xylanase composition are provided, wherein the xylanase composition comprises a xylanase and a stabilizer, and the xylanase is from an anaerobic fungus, the stabilizer comprises a polyol, and the content of the polyol is at least 40 wt %, based on the total weight of the xylanase composition.

Claims

exact text as granted — not AI-modified

What is claimed is: 
     
         1 . A method for manufacturing a xylanase composition with increased stability comprising:
 providing a xylanase;   providing a stabilizer, comprising a polyol; and   mixing the xylanase and the stabilizer to form a xylanase composition;   wherein the xylanase is from  Neocallimastix  genus, and the content of the polyol is at least 60 wt %, based on the total weight of the xylanase composition, wherein the polyol is selected from the group consisting of glycerol, sorbitol, sucrose, and combinations thereof.   
     
     
         2 . The method according to  claim 1 , wherein the xylanase is from  Neocallimastix frontalis.    
     
     
         3 . The method according to  claim 1 , wherein the polyol is glycerol. 
     
     
         4 . The method according to  claim 1 , wherein the content of the polyol is at least 80 wt % based on the total weight of the xylanase composition.
