초록
This study was performed to investigate the antimicrobial effects of Origanum majorana L. ethanol extract against food-borne pathogens. The antimicrobial activity of Origanum majorana L. extract was determined using a paper disc method. The extract exhibited growth inhibiting activities in a concentration dependent manner on 10 species microorganisms. The extract of Origanum majorana L. showed the highest antimicrobial activity against Salmonella enteritidis. The growth inhibitory effects of Origanum majorana L. extract on food poisoning microorganisms were determined against Salmonella typhimurium and Listeria monocytogenes, gram negative and positive bacteria, respectively. The extract of Origanum majorana L. had strong antimicrobial activity against Salmonella typhimurium and Listeria monocytogenes at the concentration of 700 mg･L-1. At this concentration, the extract of Origanum majorana L. inhibited the growth of Salmonella typhimurium and Listeria monocytogenes up to 60 and 36 hours, respectively. The results in the present study demonstrate antimicrobial effects of Origanum majorana L. ethanol extract against food-borne pathogens, suggesting that Origanum majorana L. could be an effective natural antibacterial agent in food.
