Pennisetum hybrid was proved to be a prospective feedstock for cellulosic ethanol production.
The ratio of syringyl and guaiacyl units of lignin played an important role on the hemicellulose hydrolysis in LHW.
Branch degree of hemicellulose contributed more on the characterization of xylooligomers degree of polymerization.
No significant corresponding relationship was observed between increase of ED and changes of CrI, DP and surface area.
