Surfactant-assisted [EMIM]OAc pretreatment of beech wood for efficient enzymatic hydrolysis

Bioethanol is a promising green energy alternative that can utilize lignocellulosic feedstock from plant materials. However, the rigid and recalcitrant structure of lignocelluloses is a major obstacle to their efficient bioconversion. The present study investigated the pretreatment of beech wood with 1-ethyl-3-methylimidazolium acetate to improve its enzymatic digestibility. Moreover, the effect of pre-soaking in 4% Tween 20 solution prior to the ionic liquid pretreatment was assessed. The ionic liquid pretreatment significantly enhanced the substrate enzymatic digestibility by over 12-fold. The use of surfactant successfully intensified the impact of ionic liquid pretreatment on beech wood composition and its hydrolysis yield.
