摘要
以米曲霉(沪酿3.042)为出发菌株,经紫外诱变与化学诱变,通过培养筛选,得到一株变异菌株A11。其蛋白酶活性比原菌株(3447U)提高了3688U,耐温性能较强,遗传稳定性较好。
The Aspergillus oryzae-Huniang 3.042 start strain was mutated multiply by UV and EDS, a mutant strain A11 was obtained by separation, purification and cultivation. The mutant strain's enzyme activity of proteinase was increased 3688U to compare with the original (3447U), and the hot-resistant character was stronger than the original, the hereditary characters of the mutant strain were very stable.
