Title:
METHOD FOR PRODUCING SUGAR AND ALCOHOL FROM CELLULOSIC BIOMASS, AND MICROORGANISMS USED FOR SAME
Document Type and Number:
WIPO Patent Application WO/2013/115305
Kind Code:
A1
Abstract:
Obtained are microorganisms belonging to the genus Trichoderma, which express a β-glucosidase gene (bgl1) derived from microorganisms belonging to the genus Aspergillus under the control of a promoter for egl1 of the microorganisms of the genus Trichoderma. It has been discovered that the use of a diastatic enzyme produced by this transformant enables efficient saccharification of cellulosic biomass. It has also been discovered that fermenting the cellulosic biomass thus saccharified enables efficient production of ethanol.
