The aim of this study was screening of 45 Lactobacillus strains for bacteriocin genes using polymerase chain reaction (PCR) with specific primers and using DNA/DNA hybridization with specific probes.Specific PCR products were detected for gassericin K7A (6 strains), gassericin K7B (5 strains), acidocin A (1 strain), acidocin B (1 strain), gassericin T (6 strains), gassericin A (2 strains) and lactacin F (0 strain) using PCR and specific primers. The results were confirmed for gassericin K7A and gassericin K7B using DNA/DNA hybridization with exception one strain.
