Document Type and Number:
WIPO Patent Application WO/2019/044887
Kind Code:
A1
Abstract:
The purpose of the present invention is to extract and provide a β-glucosidase gene having the effect of efficiently promoting saccharification in hydrolysis of cellulose-containing biomass from a hardly culturable symbiotic protozoan community in Coptotermes formosanus, and the present invention specifically relates to a β-glucosidase derived from protozoans of genus Pseudotrichonympha, comprising the amino acid sequence represented by SEQ ID NO: 1.
