It was indicated that the ratio of syringyl and guaiacyl units of
lignin played an important role on the hemicellulose hydrolysis in LHW than branch degree, but latter
contributed more on the characterization of xylooligomers degree of polymerization. Moreover, the analysis
of multi-scale changes of substrate suggested that cellulose crystallinity index and degree of
polymerization seemed no direct relationships for increase of enzymatic digestibility
