Title
(EN) METHOD FOR PRODUCING ETHANOL
Abstract
(EN)
The method for producing ethanol according to the present invention comprises (A) a step for mixing a pretreated lignocellulosic biomass with an enzyme to saccharify the lignocellulosic biomass, and (B) a step for inoculating, with a yeast, and fermenting a saccharification liquid and saccharification residue obtained in step (A), wherein: the yeast is Saccharomyces cerevisiae; and the method comprises, before step (A), or after step (A) but before step (B), (M) a step for determining the concentration of yeast cells in step (B) so as to equal to a preset reference value depending on the concentration of furfural in a liquid containing the pretreated lignocellulosic biomass before step (A) or the saccharification liquid obtained in step (A), wherein the preset reference value is the concentration of yeast cells which is higher than or equal to the critical value of the concentration of yeast cells at which fermentation is not inhibited depending on the concentration of furfural, and the yeast is inoculated in step (B) such that the concentration of yeast cells determined in step (M) is attained.
