| 摘 要： | 利用自己设计的筛选方法，从不同的酿造曲样中筛选出1株产纤溶酶酶活较高的米曲霉菌株SA-6，其产纤溶酶酶活为25U／mL。SA-6经过紫外线、^60Co和亚硝基胍诱变，筛选得到突变株NA-25，其产酶酶活为63U／mL，是出发菌株SA-6的2．52倍。突变株NA-25的发酵性状改变，其产纤溶酶的高峰比出发菌株迟了约10h。

| Abstract: | A Asperillus Oryzae strain,SA-6 was isolated with different screening methods and the fibrinolytic enzyme activity was 25 U/mL.A mutant was then isolated after SA-6 was treated with UV,~(60)Co and NTG and the relevant firbrinolytic enzyme activity was enhanced to 63 U/mL which was 1.52 times higher than that of SA-6.Comparing with the starting strain,the appearance time of the maximum fibrinolytic enzyme production of the mutant was delayed 10 hours. |
