Abstract
This study was carried out to investigate antimicrobial activities of ethanol extracts from 12 kinds of spices against Lactobacillus plantarum and Leuconostoc mesenteroides to kimchi fermentation. Lactic acid bacteria were isolated from fermenting kimchi, were identified as Leu. mesenteroides, Lac. sake, Lac. plantarum and Pediococcus pentosaceus. The ethanol extracts of cardamon, thyme and cumin among 12 spices showed antimicrobial activities against Lac. plantarum, while they did not showed the activites against Leu. mesenteroides through paper disc method. In addition, the growth of Lac. plantarum was inhibited in MRS broth containing each of cardamon(>4%), thyme(>4%) an cumin(>1%).
