Fig. 7From: Epoxidation and etherification of alkaline lignin to prepare water-soluble derivatives and its performance in improvement of enzymatic hydrolysis efficiency a Effect of enzymatic hydrolysis time and additive concentrations of LP6001.2 on enzymatic hydrolysis. b Glucose yields of the enzymatic hydrolysis at 48 h with different additives at 0.12 % concentration; the concentration of Tween-80 was set at 0.2 %. The error bars are standard deviations from experiments performed in triplicateBack to article page
