Abstract

Comparing analysis of complete nucleotide successions of the genes 16S pPHK of closely related subspecies of the industrial strains Lactococcus lactis applied as starter cultures for fermented milk products manufacturing was made. Possibility to apply the method for identification of two subspecies of Lactococcus lactis: cremoris and lactis was shown. Existence of unique replacements in the proximal area of the gene 16S pPHK subspacies cremoris has been demosntated that allows precisely identify the cultures L.lactis subsp: cremoris and L. lactis subsp. lactis.
