Abstract
Nizin is produced by Str. lactis, strain MSU. During biosynthesis it is excreted into the fermentation broth and gradually adsorbed on the organism cells. This was confirmed by experiments with an inactive variant of Str. lactis IIa. The cells of this culture adsorbed nizin from "active" fermentation broth. Adsorption of nizin depended on pH of the medium; at pH 2,3 the cells did not adsorbe the antibiotic and at pH 6.6 the amount of the antibiotic adsorbed by the cells was maximum.
