【摘要】 纤维素糖化是甜龙竹蛀粉燃料乙醇发酵研究中的重要内容。正交试验和对比试验结果表明,在pH值为4.4、温度为55℃,酶用量为200u/g,酶解时间小于20h条件下,进行纤维素酶解较合适,但酶解率较低。通过酸或碱并结合有机溶剂进行预处理能显著提高蛀粉纤维素糖化率。同时添加半纤维素复合酶进行酶解,能使蛀粉中大部分半纤维素水解,并能促进纤维素的酶解。更多还原

【Abstract】 It is the significant step for saccharification of bores powder cellulose from dendrocalamus to be used In the preparation of fuel ethanol.The results of orthogonal test and comparing test show that the condition of pH4.4,55 ℃,200 u/g of enzyme quantity in 20 hours is more suitable for bores powder cellulose hydrolysis with low rate still. The combination of acid or alkali and organic solvents for pretreatment can significantly improve the rate of saccharification of bores powder cellulose. Adding simultaniously compound enzyme for hemicellulose hydrolysis is enabling the majority of bores powder hemicellulose hydrolysis,and can promote the hydrolysis of cellulose.更多还原
