Enhanced enzymatic hydrolysis of corn stover using twin?screw extrusion under mild conditions

This paper aims to investigate the effect of extrusion at high solid loading on corn stover (CS) properties and its enzymatic hydrolysis. biomass was extruded under different screw speeds loadings impact these parameters physicochemical evaluated. It found that lignocellulosic components were not significantly affected by pretreatment, while surface area increased with rotation speed. Different enzyme cocktails used for hydrolysis untreated CS. Overall, mild twin-extrusion enhanced CS through an increase in glucose xylose yields 134–212% 214–294%, respectively, when using Trichoderma longibrachiatum cellulase.
