  1. Notes: Values of cellulose, hemicellulose and lignin after bio-pretreatment were presented as the relative content. Degradation rate of cellulose after M.V. pretreatment = [10 × 38.34% − (10 − 10 × 23.67%) × 48.79%]/(10 × 38.34%) × 100% = 2.78%, the other degradation rate of each components after different pretreatment were calculated by the same method, and the degradation rate of cellulose after P.C. pretreatment was 17.02%; the degradation of lignin degradation rate after M.V. pretreatment was 42.30%; the degradation of lignin degradation rate after P.C. pretreatment was 30.04%. Each value was the mean of the three replicates.
