Abstract

When ingredients of Kimchi were mixed and stored in $18^{\circ}C$, lactic acid bacteria, such as Leuconostoc mesenteroides and Lactobacillus plantarum, were selectively grown up. Herefore, to understand why lactic acid bacteria were selectively cultured in Kimchi, antibacterial activities of Kimchi ingredients against some pathogens and Kinlchi lactic acid bacteria were investigated. Kimchi mixed with all ingredients significantly inhibited the growth of all tested pathogens: S. typhimurium, S. sonnei, and E. coli. Kimchi without green onion, garlic or ginger inhibited the growth of S. typhimurium, but did not E. coli and S. sonnei. However, Kimchi without red pepper powder did not inhibit the growth of all tested pathogens. All ingredients of Kimchi did not inhibit the growth of L. plantarum and L. mesenteroides. These results suggest that Kimchi ingredients can synergistically inhibit the growth of pathogens and Kimchi may be a selective medium for lactic acid bacteria.
