Abstract

The present invention relates to novel xylanase having alkali resistance, which corresponds to glycoside hydrolase family 10 (GH10) isolated from Micobacterium sp. HY-17 strain. More specifically, the xylanase is a novel enzyme which is stable in an alkali environment, effectively hydrolyzes various xylans, hydrolyzes beta-glucan, and degrades cellobiose. Thus, the zylanase of the present invention can be used as an enzyme in the food industry, an enzyme for feed, a biomass pretreatment enzyme, and a useful enzyme for various industry groups including a pulp process.

Description

technical field

[0001] The present invention relates to a new xylanase with alkali-resistance properties, which is isolated from the strain of Micobacterium sp. HY-17 and belongs to glycoside hydrolase family 10 (glycosidehydrolase family 10, GH10). Background technique

[0002] A great deal of research has been conducted to use various carbon sources as raw materials. Starch polysaccharides contained in this raw material are easily hydrolyzed and are mainly used in the food industry. Therefore, in order to use carbon sources as raw materials in various industrial groups, the necessity of nonstarch polysaccharides (Nonstarch polysaccharides) is increasing.

[0003] Xylan (Xylan) is a non-starch polysaccharide that exists in woody, plant and grain by-products. Non-starch polysaccharides can be divided into cellulose and hemicellulose, and the important component of hemicellulose is xylan. Xylanase is an enzyme that hydrolyzes this xylan (xylan) into xylose, xylobiose, and ...
