【摘要】 利用羧甲基纤维素钠为唯一碳源培养基从朽木、腐烂的竹叶与稻草中分离得到8株纤维素分解菌,测定了其产酶活性。对其中产酶活性较高的2#菌株进行紫外线诱变,进一步筛选得到突变株M10,其相对酶活较出发菌株提高了89.1%。更多还原

【Abstract】 Eight strains of microbes degrading cellulose were isolated from putrid wood,bamboo sheet and straw on medium using sodium carboxymethylcellulose as the sole carbon source.The mutant strain M10 was obtained from strain 2# by UV irradiation.Its enzyme activity increased 89.1% than the original strain.更多还原
