김치에서 분리한 Lactobacillus plantarum과 Leuconostoc mesenteroides에 대한 향신료 에탄올추출물의 선택적 항균효과

Selective Antimicrobial Effects of Spice Extracts Against Lactobacillus plantarum and Leuconostoc mesenteroides Isolated from Kimchi.

Abstract

This study was performed to investigate antimicrobial effects and their actions of the ethanol extracts of 12 spices against Lactobacillus plantarum and Leuconostoc mesenteroides, which are related to Kimchi fermentation. The cardamon, thyme, and cumin ethanol extracts among 12 spices showed antimicrobial activities against Lac. plantarum, not against Leu. mesenteroides through paper disc method. The growth of Lac. plantarum was inhibited in MRS broth containing each extracts of cardamon (>4%), thyme (>4%) and cumin (>1%). SDS-PAGE and transmission electron micrographs showed that the cell walls and membranes were disrupted and the cytoplasmic components were leaked in strains treated with ethanol extracts.
