Title:
METHOD FOR PRODUCING STARTING MATERIAL FOR ENZYMATIC SACCHARIFICATION, METHOD FOR PRODUCING SUGAR, AND METHOD FOR PRODUCING ETHANOL
Document Type and Number:
WIPO Patent Application WO/2012/096236
Kind Code:
A1
Abstract:
A method for producing a starting material for enzymatic saccharification according to the present invention comprises: a modified biomass production step for treating a lignocellulose-containing plant biomass material with a treating agent containing ammonia to give a modified biomass; and a water treatment step for immersing the modified biomass in water at 40-100°C and thus eluting polysaccharides in the modified biomass in water to give a starting material to be subjected to an enzymatic saccharification step. Thus, the present invention can provide a method for producing a useful starting material for enzymatic saccharification, said starting material being usable in a method for producing a sugar, enabling efficient performance of the enzymatic saccharification and ensuring an increase in the productivity of the sugar.
