[Bacteriocin sensitivity as a supplementary taxonomic sign of bacteria belonging to the genus Lactobacillus].

It was shown that 90.6 per cent of the Lactobacillus isolates belonging to 15 species was sensitive to one or more lactocin types. Lactocins produced by bacteriocinogenic strains of Lactobacillus in liquid media are characterized by a narrow spectrum limited by the representatives of Lactobacillus. The lactocin sensitivity test may be used with taxonomic purposes as an additional indication of the bacteria belonging to Lactobacillus. A kit of 8 bacteriocinogenic strains of Lactobacillus producing 8 lactocin types is recommended to be used in determination of Lactobacillus sensitivity to bacteriocins.
