Title:
METHOD OF PREPARING SUGAR SOLUTION
Document Type and Number:
WIPO Patent Application WO/2016/047589
Kind Code:
A1
Abstract:
The method of preparing a sugar solution according to the present invention is a method of preparing a sugar solution from cellulose-containing biomass, the method including step (1): a step for obtaining an endoxylanase hydrolysate by hydrolyzing the cellulose-containing biomass using endoxylanase derived from microorganisms of the Acremonium genus or the Aspergillus genus, step (2): a step for separating the endoxylanase hydrolysate into an endoxylanase hydrolysate solid and an endoxylanase hydrolysate liquid through solid-liquid separation, step (3): a step for obtaining a cellulase hydrolysate by hydrolyzing the endoxylanase hydrolysate solid using cellulase derived from a filamentous fungus, and step (4): a step for filtering the cellulase hydrolysate through an ultrafiltration membrane to collect a sugar solution from the filtrate side and collect an enzyme component from the non-filtrate side.
