英文摘要Blocking the unproductive adsorption of cellulase to lignin has been popularly thought to be the chief mechanism of non-ionic surfactant improving enzymatic hydrolysis of lignocellulose. This study, however, proposes a different viewpoint. Laccase and hemicellulase-xylanase (HXase) which respectively modify lignin and degrade hemicellulose were used to treat raw and ball-milled sugarcane bagasse (SCB). The treated SCB maintained similar relative lignin and hemicellulose contents as the untreated SCB. Laccase treatment resulted in wrinkles on the SCB micro-surface, while HXase treatment led to the formation of many pores in SCB. It found that Tween20, a kind of non-ionic surfactant, could obviously facilitate the adsorption of cellulase to untreated and treated SCB. It was completely opposite to the abovementioned popular mechanism. The enzymatic hydrolysis efficiencies of raw SCB treated by laccase and HXase, ball-milled SCB treated by laccase for 72 h and HXase for 24 h or 72 h, and ball-milled SCB treated by HXase for 24 h with Tween20 addition were 26.10%, 61.65%, 61.42%, and 70.86%, respectively, which had significant differences against those without Tween20 addition. Combined with surface structure observations, it hints that the enhancing effect of a non-ionic surfactant on the enzymatic hydrolysis of lignocellulose tends to depend on the lignocellulosic structural feature rather than lignin presence.
