Abstract

Lactococcin, a bacteriocin produced by subsp. lactis ADRIA 85LO30, was purified as a 2.3-2-4 kDa peptide. Six non-bacteriocin-producing (Bac) and non-immune (Imm) strains were isolated after curing experiments. These strains had in common the loss or modification of two plasmids: pOS4 (32 kb) and pOS5 (70 kb). By comparing pOS5 and several modified plasmids, a DNA region from pOS5 of about 10 kb, which was necessary for wild-type bacteriocin production and immunity, was identified.
