摘要：以酸、碱及蒸汽爆碎预处理的蔗渣、杨树作底物，进行纤维素酶解（５０℃、２４ｈ）试验，其中以碱预处理的蔗渣得糖率为最高。通过测定不同原料不同预处理方法得到的水解液的总糖、糖组分及紫外吸收；分析不同预处理所引起的植物纤维组成变化、同时对预处理前后的蔗渣和杨树进行了ｘ－衍射分析测定，从结晶度的变化综合分析了预处理对纤维素酶降解的影响，并对植物纤维生物量的全利用进行了初步探讨。
Bagasse and chopped poplar wood were used as substrates for studying the effects of pretreat-ments on enzymatic hydrolysis of cellulose. Pretreatments by acid ,alkali and steam-explosion and enzymatichydrolysis at 50℃ for 24 h were adopted in the experiments, Pretreated materials were analysed by de-terming total sugar,sugar fraction and lignin contents in the hydrolyzates. The crystallinity of bagasse andpoplar before and after pretreatments was estimated by X-ray diffraction。 Effects of different pretreatrnentson variations of composition and enzymatic hydrolysis of cellulosic materials were seen from the results andthe total utilization of biomass of these materials was tentatively discussed.
