Title:
METHOD FOR PRODUCING GLUCOSE
Document Type and Number:
WIPO Patent Application WO/2013/137151
Kind Code:
A1
Abstract:
A thermophilic anaerobic microorganism is cultured in the presence of cellulose and β-glucosidase, whereby a cellulase is produced to decompose the cellulose into a saccharide such as cellooligosaccharide, the resultant cellooligosaccharide is further decomposed with β-glucosidase into glucose and the glucose is accumulated in a culture medium. Alternatively, a thermophilic anaerobic microorganism is cultured in the presence of a mixture of starch and cellulose, β-glucosidase, α-amylase and glucoamylase, whereby a cellulase is produced to decompose the starch-cellulose mixture into glucose and the glucose is accumulated in a culture medium.
