General description

Xylanase is a hemicellulolytic enzyme. It is synthesized by microorganisms like bacteria, yeast and fungi.
Xylanase from Trichoderma viride was shown to have molecular weight of 22 kDa with a Pi of 9.3.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in cellulosic ethanol research. For more information see the article in biofiles and Enzymes for Alternative Energy Research


Xylanase from Trichoderma viride has been used as a component of an enzyme mixture for the hydrolysis of hemicellulose-rich solution (autohydrolysate). It has also been used as a cell-wall degrading enzyme to determine the efficiency of p-coumaryl esterase to release p-coumaroyl and feruloyl group.

Biochem/physiol Actions

Xylanase (endo-1,4-β-Xylanase) is involved in the hydrolysis of xylan. It has a wide range of applications in industrial processes such as, bioleeching of craft pulp in paper industry and production of hydrolysates from agro-industrial wastes. Xylanase is also used in nutritional enhancement of lignocellulosic feed and in clarification of juice and wines.

Unit Definition

One unit will liberate 1 μmole of 4-nitrophenol from 4-nitrophenol-xylan per min at pH 4.5 at 30 °C.
