Title:
VARIANT OF CELLULASE-PRODUCING FUNGUS, CELLULASE MANUFACTURING METHOD, AND CELLO-OLIGOSACCHARIDE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/142325
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a variant of a cellulase-producing fungus, a cellulase manufacturing method, and a cello-oligosaccharide manunfacturing method using the cellulase, the variant of a cellulase-producing fungus enabling the preferential production of cello-oligosaccharides when selectively generating cello-oligosaccharides by the enzymatic decomposition of a cellulosic substance in the presence of cellulase. The present invention relates to a cellulase-producing fungus variant in which cellobiohydrolase and β-glucosidase genes have been knocked out.
