Enterococcus faecium CWBI-B1430 and Enterococcus mundtii CWBI-B1431 from artisanalproduced Peruvian cheeses showed the presence of 4 putative bacteriocin genes: enterocin A, enterocin B, enterocin P, and mundticin KS. The multiple bacteriocin producer E. faecium CWBI-B1430 presented 1 plasmid of 34.6 kb, whereas E. mundtii CWBI-B1431 contained 1 plasmid of 11.0 kb. The structural gene responsible for mundticin KS production was located on 5.6 and 3.1 kb HindIII plasmid fragments. The reverse transcription-PCR analysis showed the expression of the bacteriocin genes enterocin A, enterocin B, and mundticin KS in E. faecium CWBI-B1430 and the bacteriocin genes enterocin P and mundticin KS in E. mundtii CWBI-B1431. To our knowledge, this is the first report of the expression of mundticin KS in E. faecium and enterocin P in E. mundtii.
