In spite of differences in producing strains and their plasmid profiles, amino acid sequence analysis indicates that the bacteriocin produced by Pediococcus acidilactici SJ‐1 is identical to that produced by PAC 1.0 and H. Protoplasts prepared from cells of pediocin‐resistant strains of Lactobacillus plantarum and Lact. fermentum were lysed by exposure to the pediocin. The interaction of the pediocin with sensitive Lact. plantarum cells did not alter the fluidity of the cell membrane.
