摘要
利用黑曲霉为出发菌株,经过紫外线和亚硝酸复合诱变,选育出一株高产纤维素酶的菌株,与出发菌株相比,纤维素酶高产菌株CMC酶活力提高了58.7%,滤纸酶活力提高了60.6%,而且产酶性能稳定。
Used as the starting strains of Aspergillus niger, after ultraviolet and mutation of nitrite, to a breeding high-yield strains of cellulose, Compared with the original strain, high-yielding cellulase strain CMC activity increased 58.7 percent, filter paper activity increased 60.6 percent, and production of stable performance
