[Bacteriocin typing of Lactobacillus cultures using a basic set of bacteriocinogenic strains]

Lactic bacilli of 15 species were divided into 78 bacteriocin types by their sensitivity spectra with respect to the main set of the bacteriocinogenic strains. L. acidophilus-L. salivarious, L. jugurti, L. casei, L. plantarum, L. fermentum, L. brevis, L. buchneri, L. helveticus, L. lactis and L. leichmannii were used in the study. The cultures were divided into 30, 9, 7, 25, 5, 20, 13, 8, 2.2 and 2 bacteriocin types respectively. The method of determining the lactic bacilli sensitivity spectra to 8 bacteriocinogenic strains of the main kit is simple and economic. It allows marking of lactic bacilli and their dividing into bacteriocin types within the species. This may be used in taxonomy and epidemiological studies.
