[Sensitivity of the lactobacilli of the subgenus Streptobacterium to bacteriocins of lactobacilli of different species].

Sensitivity of 167 cultures of Lactobacilli of Streptobacterium to 39 bacteriocins produced by L. acidophilus, L. jugurti, L. salivarius, L. lactis, L. helveticus, L. casei, L. plantarum, L. fermenti, L. brevis and L. buchneri was studied. It was found that the cultures of L. casei were sensitive to 30 types of bacteriocins, while the cultures of L. plantarum were sensitive to 9 bacteriocin types. 89.6 per cent of the cultures of L. casei and all cultures of L. plantarum were sensitive to one or several bacteriocins produced by Lactobacilli of different species.
