On Opatimize and Mutagenesis to Efficient Strains of Ramie Fiber

LU Bi-tao , CHEN Jing-hao , WANG Tian-you , LAN Guang-qian

摘要: 从已经得到的高效脱胶菌株中选出脱胶效果更好、环境条件依赖更小的菌株，并对该菌株进行紫外灯照射处理，通过对比20 s ，40 s ，60 s照射后的致死率，最后选择了照射60 s的条件，诱变后分别测试相应菌株的果胶酶、木聚糖酶、甘露聚糖酶、纤维素酶的活力。结果表明：采取该条件诱变后，菌株的脱胶关键酶的活性均有一定程度的提高，并通过连续测试四代的酶活力，发现各代之间酶活力变化不大，证明诱变后酶活力能稳定遗传。通过3个菌株的脱胶效果的比较，诱变后菌株1－1的脱胶效果较高且稳定。
