Pretreated samples in our study were washed with water until neutralized to pH 7.0, but this step required a lot of water, about 300 times the weight of substrate used, because the pretreated sample was sticky and swollen. It was theorized that there was still a small amount of surfactant left in the washed fibers, and that residual surfactant may help enzymatic hydrolysis. Figure 4 shows the effect of residual surfactant after pretreatment on digestibility at 72 h. To see this effect, newspaper was pretreated without surfactant, and then a given amount of surfactant was added to... 

A study was conducted to examine the effects of several parameters on the yields of enzymatic hydrolysis for two major MSW components namely, newspaper and corrugated cardboard [74], The primary aim was to try to determine the modifications of MSW that would lead to increased conversions to ethanol. A full complement cellulase system from T. reesei QM 9414G was used. The enzyme system consisted of endoglucanase,...
