초록
전남 목포시의 각 가정에서 담근 물김치에서 총 24균주의 유산균을 분리하였다. 이들 분리 유산균 중 5균주가 인공위액에서 내성을 나타내었다. 이들 유산균은 Lactobacillus plantarum으로 동정하였고, 특히 물김치로부터 동정된 유산균 MUL-2, MUL-4, MUL-18은 인공위액에서 3시간 배양 후에도 초기 생균수에 비해 변화가 거의 없어 가장 강한 내성을 나타내었다. 이들 분리 유산균은 병원성 미생물인 Listeria monocytogenes, Esherichia coli, Staphyrococcus aureus, Vibrio parahaemolyticus, Samonella typhimurium에 대해 뚜렷한 항미생물활성을 나타내었다.
Abstract
Five strains out of tweeny four strains of lactic acid bacteria isolated from Mul-Kimchi showed a resistance in the artificial gastric juice. These lactic acid bacteria were identified as Lactobacillus plantarum species. In particular, lactobacilli MUL-2, MUL-4 and MUL-18 showed a strong resistance and their viable cell counts of the initial stage were not changed after the 3 h cultivation in the artificial gastric juice. The isolated lactic acid bacteria showed the antimicrobial effect against Listeria monocytogenes, Escherichia coli, Staphylococcus aureus, Vibrio vulnificus, and Salmonella typhimurium in the paper disc method.
