In this study, the characterization of bacteriocin produced by Enterococcus mundtii YB6.30 with antilisterial activity isolated from fermented sucuk was aimed. The YB6.30 inhibited various Gram-positive and Gram-negative bacteria, including Listeria species, as well as food pathogens such as Staphylococcus aureus, Bacillus cereus, Salmonella Enteritidis, S. Typhimurium and Escherichia coli. As a result of proteolytic enzyme treatment, the antimicrobial substance produced by YB6.30 was identified as bacteriocin. Identification of E. mundtii YB6.30 was done by 16S rRNA gene sequence analysis and polymerase chain reaction (PCR) using species-specific primers. As a result of different temperature and pH treatments, it was determined that bacteriocin is heat stable and shows activity in wide pH range (2.0-10.0). Bacteriocin showed a bactericidal activity against vancomycin resistant E. faecium ATCC 51559. As a result of the PCR experiment, the presence of mundtisin KS gene was detected in E. mundtii YB6.30. Molecular size of active protein band was determined as 7.56 kDa as a result of Tricine-SDS-PAGE analysis.
