In pediocin AcH producing Pediococcus acidilactici strains the genes for both the production of pediocin and immunity against it are encoded in an 8.9 kb plasmid pSMB74. Following loss of this plasmid, the variants lost the ability to produce pediocin AcH, but some retained the resistance against it. This resistance was a transient trait, acquired while nonproducing cells grew in the presence of pediocin AcH but lost when the cells were grown in the absence of it.
