[Data on the cultural and morphologic features of dissociation forms of nisin-producing Streptococcus].

Colonies and cells of S and G variants of Streptococcus lactis, strain MSU were studied comparatively. It was shown that in the G form the growth rate and other biosynthetic peculiarities and in particular the capacity for the nisin synthesis were lower. Morphological properties of the colonies and cells of the S and G variants of the nisin-producing streptococcus were investigated.
