식중독 유해균에 대한 해외 식물 추출물의 항균활성

초록

This study was performed to determine the inhibitory effects of tropical plant extracts on four foodborne pathogens (Salmonella Typhimurium, Bacillus cereus, Staphylococcus aureus, and Listeria monocytogenes). Five hundred plant extracts were obtained from the International Biological Material Research Center and screened; five were found to display an inhibitory effect on foodborne pathogens. The antimicrobial activity was estimated by the disk diffusion method, which was used to measure the clear zone and to determine the minimum inhibitory concentration of the plant extract. Among the extracts tested, Lithocarpus tubulosus and Corylopsis sinensis showed notable bactericidal effects against S. Typhimurium, B. cereus, S. aureus, and L. monocytogenes, which suggested their potential use as potent natural additives for the food or cosmetic industries.
