Abstract

Provided is a method for producing ethanol from a lignocellulose biomass at low cost using yeast. The method for producing ethanol from a lignocellulose biomass according to the present invention comprises (1) a step of pretreating the lignocellulose biomass (2) a step of treating a cellulose fraction obtained in step (1) with a cellulose hydrolase (3) a step of mixing a glycosylated biomass obtained in step (2) with yeast to perform ethanol fermentation and (4) a step of separating a fermentation product obtained in step (3) into a solid material and a liquid material wherein a cycle comprising the above mentioned steps (1), (2), (3) and (4) is repeated at least two times and yeast obtained in step (4) is used as the whole or a portion of the yeast to be used in step (3) in the next cycle.
