Abstract
Production of bacteriocin activity designated pediocin PA-1 was associated with the presence of a 6.2-megadalton plasmid in Pediococcus acidilactici PAC1.0. The bacteriocin exhibited activity against P. acidilactici, P. pentosaceus, Lactobacillus plantarum, L. casei, L. bifermentans, and Leuconostoc mesenteroides subsp. dextranicum. Partial characterization of pediocin PA-1 is described. The molecular weight of pediocin PA-1 was ca. 16,500. Additionally, strain PAC1.0 was found to contain a 23-megadalton plasmid associated with sucrose-fermenting ability.Keywords
