Effect of addition of different lignin samples in the system on protein content and activities of CBH, EG, BGL, and xylanase in the supernatant, and enzymatic hydrolysis of avicel, PASC, and holocelluose. a Effect on protein content and enzyme activities of BGL, EG, CBH and xylanase, in which reduced ratio was based on protein content and enzyme activities in the reaction system without lignin. b–d Effect on enzymatic hydrolysis of avicel, PASC, and holocellulose
