Association of a 13.6-Megadalton Plasmid in Pediococcus pentosaceus with Bacteriocin Activity.

摘要: Pediococcus pentosaceus FBB61 and L7230, isolated from cucumber fermentations, produced a bacteriocin, designated pediocin A, which had identical activity spectra against species of Pediococcus, Clostridium, Staphylococcus, Streptococcus. Both strains possessed 13.6-megadalton plasmid (pMD136). Plasmid curing experiments suggested that both bacteriocin immunity production determinants were encoded by pMD136. Use pediocin-producing in food fermentations is discussed.
