FIELD: pulp industry.
SUBSTANCE: invention relates to a method of producing bioethanol from cellulose-containing material. Method involves preliminary processing of raw materials, such as straw, or fruit shells of cereals, or oil crop wastes or silver grass, or pulp of crops with diluted solution of acid with concentration of 1-14 % at temperature of 85-98 °C and atmospheric pressure for 3-18 hours, combined steps of enzymatic hydrolysis and alcohol fermentation, which is performed by means of any types of nonpathogenic ethanol-synthesising yeast, extraction of bioethanol from brew.
EFFECT: method increases output of bioethanol.
