The glucose (A), xylose (B) and total monosaccharide (C) yields after 24 h hydrolysis of ammonia fiber expansion (AFEX)-treated corn stover for various enzyme cocktails. Accellerase 1000 is a commercial preparation. Core cellulases contain CBH I, CBH II and EG I at equi-mass loading along with 2 mg/g glucan βG. The xylanases (LX3 and LX4 at equi-mass ratio) to cellulases (CBH I, CBH II and EG I) ratio is fixed at 1:3. LβX, LαGl and LArb were loaded at 0.6, 0.8 and 0.6 mg/g glucan, respectively).
