Hydrolysis of delignified corn stover using cellulase and rPcAxe at a fixed total protein dosage. a Amount of released reducing sugars determined by the DNS method. b Amount of glucose (white bars), xylose (light gray bars) and cellobiose (dark gray bars) determined by HPLC. c Concentration of acetic acid in the hydrolysate determined by HPLC. Hydrolysis reactions were performed at 37 °C for 24 h with 2% (w/v) biomass loading. Values are the means and standard deviations of triplicate experiments. Statistical significance is indicated by different letters on columns based on ANOVA (P < 0.05)
