摘要：为了研究NaOH+蒽醌预处理对竹材的化学组成及结构和对进一步酶水解的影响，本文选用采自浙江杭州的六年生竹材。一共有四种不同的处理方法，分析发现处理后的竹材中纤维素含量分别由原来的38.5%增加到46.5%、47.7%、54.4%、47.2%和46.7%.半纤维素由原来的20%增加到23%、24.2%、54.4%、24.3%和23.5%。而木质素含量却由原来的27.1%下降到17.8%、18.3%、17.4%、18.5%。X 射线衍射分析发现处理后竹材的结晶度有所升高，红外光谱分析表明部分分子间氢键断裂，更有利于提高竹材的酶水解效率，扫描电镜观察发现，处理后纤维束表面缝隙和孔洞明显增多，在纤维素酶解实验中，我们发现1%NaOH+5mg/gAQ预处理0.5小时的竹材的还原糖水解得率提高得最多。

Abstract: in order to study the chemical composition and structure of bamboo and the influence of the chemical composition and structure on the further enzymatic hydrolysis of NaOH+, this paper selects six years old bamboo from Hangzhou, Zhejiang. A total of four different treatment methods, the analysis showed that after the treatment of bamboo cellulose content respectively by the original 38.5% to 46.5%, 47.7% and 54.4%, 47.2% and 46.7%. Semi cellulose from the original 20% to 23%, 24.2% and 54.4%, 24.3% and 23.5%. While lignin content decreased from 27.1% to 17.8%, 18.3%, 17.4%, 18.5%. X-ray diffraction analysis found that treatment of bamboo crystallinity increased, the infrared spectrum analysis showed that part of the intermolecular hydrogen bond breaking, more conducive to improving the efficiency of enzymatic hydrolysis of bamboo, was observed by the scanning electron microscope, the fiber bundle surface cracks and holes was significantly increased after treatment and in cellulose enzyme solution in the experiment, we found that pre 1%NaOH+5mg/gAQ processing bamboo 0.5 hour of reducing sugar hydrolysis rate increased the most.Key words: bamboo NaOH+, enzymatic hydrolysis, enzymatic hydrolysis, xylanase, xylanase
