Role of ARA in the hydrolysis of pretreated corn stover. Hydrolysis of 10% corn stover after pretreatment with aqueous ammonia (AA-CS) by CTec2 (10 FPU/g DM) (a), or CEL (2 mg/g DM Cel5A, 8 mg/g DM Cel7A, and 0.2 mg/g DM Cel3A) (b), and XYL (2 mg/g DM), and/or ARA (2 mg/g DM) at 50 °C for 48 h. Hydrolysis of 10% AA-CS by CTec2 (10 FPU/g DM) and CEL (2 mg/g DM Cel5A, 8 mg/g DM Cel7A, and 0.2 mg/g DM Cel3A) with the addition of AXOS (4 mg/mL) and/or ARA (2 mg/g DM) at 50 °C for 48 h (c). The error bars represent the standard error of three independent experiments
