Xylanase Sunson XY20L to reduce viscosity for ethanol fermentation yield improvement
Xylanase degrades xylan and reduces the viscosity of starch slurry or culture medium containing xylan. It’s applied to ease alcohol fermentation and increase ethanol yield when raw materials rich in xylan are used, such as wheat-based raw materials.

Product Description
DESCRIPTION
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.
MECHANISM
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.
