THE METHOD FOR ENHANCING FERMENTATION EFFICIENCY OF LIGNOCELLULOSIC BIOMASS

摘要

The present invention relates to a method for improving fermentation efficiency of lignocellulosic biomass and, more specifically, to a method for improving fermentation efficiency of lignocellulosic biomass, which comprises the steps of: providing lignocellulosic biomass; acid pretreating as mixing lignocellulosic biomass and an acid solution; neutral pretreating as mixing the acid pretreated lignocellulosic biomass and an alkaline solution; obtaining a saccharified solution as saccharificating the pretreated lignocellulosic biomass; and removing organic acid as treating the saccharified solution with capacitive deionization (CDI). According to the present invention, organic acid generated during saccharificating lignocellulosic biomass can be removed through capacitive deionization (CDI) treatment, thereby increasing production efficiency of ethanol.
