Antibacterial Activity of Poncirus trifoliata Juice against Pathogenic Bacteria
병원성 세균에 대한 탱자즙의 항균효과
Abstract
For development of functional food, antibacterial effect of Poncirus trifoliata juice was examined. Strong antibacterial activities of Poncirus trifoliata juice were observed aginst Gram positive and negative pathogenic bacteria such as Baillus cereus, Bacillus subtilis, Corynebacterium zerosis, Listeria monocytogenes, Micrococcus luteus, Rhodococcus equi, Klebsiella pneumoniae, Pseudomonas aeruginosa, Vibrio alginolyticus, Vibrio cholerae, Vibrio parahaemolyticus, Vibrio vnlnificus and Yersinia enterocolitica. The minimum inhibitory concentration(MIC) of Poncirus trifoliata juice against Bacillus cereus. Listeria monocytogenes, Micrococcus luteus, Rhodococcus equi, Staphylococcus epidermidis, Citrobacter freundil and Pseudomonas aeruginosa was 2.5% and the MIC against Vibrio cholerae, Vibrio parahemolyticus, Vibrio vulnificus and Yersinia enterocolitica was 1.25%. Also, antibacterial activities of Poncirus trifoliata juice treated for 15 min at 121
기능성 식품소재 개발을 위하여 탱자즙의 항균활성을 확인하였다. 탱자즙은 Bacillus cereus, Bacillus subtilis, Coryne-bacterium zerosis, Listeria monocytobenes, Micrococcus luteus, Rhodococcus equi 등의 그림양성세균 6종, Klebsiella pneumo-niae, Pseudomonas aeruginosa, Vibrio alginolytics, Vibrio chloerae, Vibrio parahameolyticus, Vibrio vulnificus, Yersinia enterocolitica 등의 그람음성세균 7종에 대하여 비교적 높은 항균활성을 나타냈다. Bacillus subtilis, Coryne-bacterium zerosis, Listeria monocytobenes, Micrococcus luteus, Rhodococcus equi,Staphylococcus epidermidis, Citrobacter freundil및 Pseudomonas aeruginosa 등의 세균들에 대한 탱자즙의 최소억제농도는 2.5%였으며, Vibrio cholerae, Vibrio parahemoly-ticus, Vibrio vulnificus 및 Yersinia entero-colitica 등의 세균들에 대한 탱자즙의 최소 억제 농도는 1.25%이었다. 또한 최고 121
