Abstract:
1. A method for improving enzymatic hydrolysis in saccharification of a lignocellulosic material, comprising: pretreating the lignocellulosic material with an acid or SO adding at least one reducing agent, wherein the at least one reducing agent is selected from sulfur oxyanions and sulfhydryl reagents, to the slurry of pretreated lignocellulosic material or the liquid fraction thereof to decrease the enzymatic hydrolysis inhibitory properties of the 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.
