[Sensitivity of lactobacilli of the subgenus Thermobacterium to the action of bacteriocins].

Sensitivity of 278 cultures of Thermobacterium to 30 types of bacteriocins produced by L. acidophilus, L. salivarius, L. jugurti, L. casei, L. plantarum, L. fermentum, L. brevis and L. buchneri was studied with the method of delayed antagonism. It was shown that all cultures of L. Salivarius, L. jugurti, L. helveticus, L. lactis, L. leichmannii, L. bulgaricus and L. delbrueckii and 94.1 per cent of L. acidophilus were sensitive to one or several bacteriocin types. The cultures of L. acidophilus, L. salivarius and L. jugurti, L. helveticus, L. lactis, L. bulgaricus and L. delbrueckii were sensitive to 26, 15, 28, 2 and 29 lactocin types respectively.
