摘要
以HS-5乳酸链球菌为出发菌株,进行紫外线照射诱变,经初筛、复筛得到2株高产乳酸链球菌肽的稳定性菌株。其效价比原始菌株分别提高了12.41%和4.76%,效价达到了3116IU/mL和2904IU/mL。
2 high-nisin-yield strains were screened with HS-5 lactic acid streptococci as starting strains by UV radiation. The titer of the two strains increased by 12.41 % （3116 IU/mL） and 4.76 % （2904 IU/mL） respectively compared with that of the starting strains. （Tran. by YUE Yang）
