Title:
FILAMENTOUS FUNGUS MUTANT STRAIN AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/018471
Kind Code:
A1
Abstract:
Provided are the following: the construction of a filamentous fungus mutant strain with which the interference with enzyme production that is attributed to glucose is inhibited; a method for producing a glycolytic enzyme using the filamentous fungus; a method for saccharide production from a biomass; and a biomass saccharification method. The filamentous fungus mutant strains shows reduced or depleted Sre1 expression when compared to the parent strain.
