NOVEL ALKALI-RESISTANT GLYCOSIDE HYDROLASE FAMILY 10 XYLANASE PRODUCED FROM MICOBACTERIUM SP. HY-17 STRAIN

Title:

NOVEL ALKALI-RESISTANT GLYCOSIDE HYDROLASE FAMILY 10 XYLANASE PRODUCED FROM MICOBACTERIUM SP. HY-17 STRAIN

Document Type and Number:

WIPO Patent Application WO/2015/026150

Kind Code:

A1

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.
