title: Bacteriocin typing of some Lactobacillus species of the subgenus betabacterium.
abstract: One hundred and forty cultures of L. fermenti, L. brevis, and L. buchneri were tested by the method of delayed antagonism for sensitivity to 39 bacteriocins produced by lactobacillus strains of different species. According to their bacteriocin sensitivity patterns, 84 L. fermenti, 43 L. brevis and 13 L. buchneri cultures were differentiated into 26, 18 and 10 bacteriocin types, respectively. Bacteriocin typing allows not only intraspecific differentiation of L. fermenti, L. brevis and L. buchneri cultures but also a subdivision of their biochemical-physiological variants.
