Xylanase XY20L is produced by submerged fermentation of Trichoderma reesei followed by purification and formulation. Xylanase degrades hemicellulose substances and reduces the viscosity of starch slurry. It’s widely applied in alcohol industry or brewing especially when wheat raw materials are used.
The enzyme contains mainly endo β-1,4 xylanase and β-xylosidase. The former degrades xylan into oligoxylose and
xylobiose, while the latter further degrades the oligoxylose and xylobiose into
xylose. In this way, the viscosity caused by xylan is greatly reduced.
