Fig. 1. The identification of optimum CTec 2 dosage and comparison to CE. The enzyme dosage is cellulase: 0.87 FPU g1 substrate, BG: 2 U g1 substrate. Released Glc represents the amount of glucose produced by steam explosion alone. ***p < 0.001, *p < 0.05, ns = not significant (p > 0.05) compared with the sample of CE + BG.
