This study was carried out to develop a new starter culture for the fermented meat products. Nine strains of lactic acid bacteria isolated from kimchi inhibited the growth of Listeria monocytogenes. Among these nine strains, three strains showing antimicrobial activities against Escherichia coil, Staphylococcus aureus and Vibrio paraphaemolyticus were selected for further study. Growth of the strains was inhibited in MRS broth containing 5% of NaCl at $21^{circ}C$, but not at $32^{circ}C$. Nitrite depletion ratio of the strains was above 70% after 48h incubation at $21^{circ}C$, and above 90% after 48h at $32^{circ}C$ in MRS broth containing $200mu$g/ml of nitrite, Nitrite concentration of cured meats and ground meats was depleted from 87.6% to 92.3% and from 45.5 to 640.6% by addition of the selected strains for 24h at $32^{circ}C$, respectively. Three strains were identified as Lactobacillus plantarum(N4) and Lactobacillus lactis ssp. lactis(N-7, an-8).
