ABSTRACT
OBJECTIVE@#To examine the individual and synergistic anti-listerial effect of nisin and leaf essential oil of Metasequoia glyptostroboides (M. glyptostroboides) against one of the leading foodborne pathogens Listeria monocytogenes (L. monocytogenes) ATCC 19116 in milk samples.@*METHODS@#The whole (8%), low (1%) and skim (no fat content) milk samples were inoculated with L. monocytogenes ATCC 19116 along with leaf essential oil of M. glyptostroboides or nisin alone as well in combinations.@*RESULTS@#In this study, the leaf essential oil at the concentrations of 2% and 5% revealed strong anti-listerial effect against L. monocytogenes ATCC 19116 in all categories of milk samples. Nisin at the concentrations of 250 and 500 IU/mL displayed a strong inhibitory effect against ATCC 19116 as compared to the control group. Additionally, synergistic combinations of leaf essential oil (1%) and nisin (62.5, 125, 250 and 500 IU/mL) also had a remarkable anti-listerial synergism in all the tested milk samples including whole, low and skim milk after 14 days.@*CONCLUSIONS@#As a major finding, the leaf essential oil of M. glyptostroboides might be a useful candidate for using in food industry to control the growth of foodborne pathogenic bacteria as confirmed by its potent anti-listerial synergistic effect with nisin against L. monocytogenes ATCC 19116 in different milk samples.
