In order to utilize energy grasses as substrates for production of biofuels and expand the diversity of lignocellulosic feedstocks, this work developed an evaluation system considering 16 kinds of parameters related to the contents of three main compositions (cellulose, hemicellulose and lignin), inhibitors generated from the pretreatment, the extent of enzymatic hydrolysis and microbial fermentation. Giant reed, corn stalks, switch grass, pennisetum and silvergrass were investigated. Comprehensive utilization indexes of giant reed (55.0) and corn stalks (40.6) revealed that giant reed had the potential for producing biofuels but corn stalks, widely used in bio-ethanol and xylitol production, possessed high contents of inhibitors which were harmful to microbial fermentation.
为了利用能源草作为生物燃料生产的底物，并扩大木质纤维素饲料的多样性，本工作开发了一个评价体系，考虑了与三种主要成分（纤维素、半纤维素和木质素）含量、预处理产生的抑制剂、酶解程度和微生物发酵相关的 16 种参数。对芦竹、玉米秸秆、柳枝稷、狼尾草和银草进行了研究。芦竹（55.0）和玉米秸秆（40.6）的综合利用指数表明，芦竹具有生产生物燃料的潜力，但玉米秸秆作为生物乙醇和木糖醇生产的广泛应用原料，其抑制剂含量较高，对微生物发酵有害。
