Abstract

Ionic liquid heat (IL-heat) pretreatment for the downstream processing of enzymatic saccharification was tested in this study. Three lignocellulosic materials—bagasse, rice straw, and rice husk—were treated in 1-n-ethyl-3-methylimidazolium acetate ([Emim]OAc) under conditions of various temperatures and reaction times. The cellulase saccharification ratio was 70% for bagasse powders after IL-heat pretreatment at 110℃ for 2 hr.
