| 摘 要： | 从5种菌株中,通过初筛和复筛筛选出一种变色范围大,产乳酸量高的菌株D(产酸量为69.36g/L),以此菌株作为出发菌,进行紫外诱变育种。从诱变处理后的计数平板上,选取10株hc值大的菌株,通过复筛最终选出了一株平均产乳酸量高的菌株D_6,其产乳酸量平均为71.73 g/L,比出发菌株高出2.37g/L。

| Abstract: | A high-yield strain D(69.36 g/L)was selected from 5 strains(A,B,C,D,E).Ultraviolet ray mutation breeding was carried out by using strain D as original strain.The mutation treatment and final screening results show that the yield of lactic acid of strain D6 is 71.73 g/L and 2.37 g/L higher than that of original strain. |
