Resumen de: AU2023414181A1
The present invention provides a method which is for producing ethanol and in which the permeation flow rate when performing membrane separation is improved. In more detail, provided is a method for producing ethanol, the method comprising: a first step for generating ethanol through saccharification and fermentation in a reaction system containing a lignocellulose-based raw material, a saccharifying enzyme, yeast, and water; and a second step for processing, by using a separation membrane, a first mixture containing ethanol, water, yeast, the saccharifying enzyme, and a lignocellulose-based raw material reaction residue obtained in the first step to acquire a mixture containing ethanol and water, and a second mixture containing yeast, the saccharifying enzyme, water, and the lignocellulose-based raw material reaction residue. The solid content concentration of the first mixture is 4-9.5 mass%.
