| Abstract: | WY-4 was a variant strain of Lactococcus lactis ssp.lactis(1.2030) obtained through microwave mutagen treatment, its Nisin activity was 511.56 IU/mL determined by the agar diffusion assay and its Nisin yield was 42.13 % higher than that of the primitive strain. The hereditary characters of the mutant strain were stable after several subcultures. |
