Abstract
A method is provided for improving enzymatic hydrolysis in saccharification of a lignocellulosic material. The method is comprising pretreating the lignocellulosic material to obtain a slurry ofpretreated lignocellulosic material; adding at least one reducing agent to the slurry of pretreated lignocellulosic material or the liquid fraction thereof to decrease the enzymatic hydrolysis inhibitory properties of slurry of the pretreated lignocellulosic material or the liquid fraction thereof; and subjecting the slurry of pretreated lignocellulosic material or the liquid fraction thereof to enzymatic hydrolysis in the presence of the at least one reducing agent.
