<p><P>PROBLEM TO BE SOLVED: To provide a method for producing ethanol by efficiently converting, into ethanol, hexose and pentose contained in a saccharified liquid obtained by hydrolyzing lignocellulosic biomass. <P>SOLUTION: The method for producing ethanol from lignocellulosic biomass by fermentation includes the following steps: A saccharified liquid is subjected to fermentation from hexose using a relevant yeast or bacterium, and while simultaneously feeding an inert gas, the ethanol is removed. Thereafter, a pentose-fermenting microorganism is used in the resultant fermented liquid after primary fermentation, without separating microbial cells from the fermented liquid, thus performing fermentation from pentose. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
