Title:
METHOD FOR PRODUCING ETHANOL
Document Type and Number:
WIPO Patent Application WO/2012/114610
Kind Code:
A1
Abstract:
A method for producing ethanol from a cellulose-containing starting material has: a saccharification step for adding a sugar-containing solution-derived fermented liquor to the cellulose-containing starting material, and saccharifying the resulting product; and a fermentation step for ethanol-fermenting the sugar solution obtained during the saccharification step. The method for producing ethanol is characterized in that the sugar-containing solution-derived fermented liquor is obtained by ethanol-fermenting at least one type of sugar-containing solution selected from a group consisting of an agricultural product liquid extract containing water-soluble sugars, molasses, and the enzyme-treated product of a grain.
