At last, three strains of high activity was induced mutagenesis by ntg, after the routine screening procedures, activity of n28 and n118 was higher 47. 5 and 40. 9 percent than that of a. niger an01001, and higher 29. 5 and 23. 7 percent than that of a199
最後，用亞硝基胍對產酶較高的3個菌株誘變，經復篩后， n28和n118的酶活比黑麴黴an01001高出47 . 5和40 . 9 ，比a199高出29 . 5和23 . 7 ， n28和n118經過5次連續傳代后，產酶能力基本穩定。 -
