- This study was undertaken to evaluate the effect of nisin and cone essential oil of Metasequoia glyptostroboides against Listeria monocytogenes ATCC 19116 inoculated in whole (8%), low (1%) and skim (no fat content) milks. Essential oil at the concentrations of 2% and 5% revealed strong antilisterial effect against L. monocytogenes ATCC 19116 in all categories of milks. Nisin at the concentrations of 250 and 500IU/ml displayed a remarkable antilisterial effect as compared to the control group. Also, the synergistic combinations of cone essential oil (1% and 2%) and nisin (62.5, 125, 250 and 500IU/ml) had a remarkable antilisterial activity in all categories of whole, low and skim milks after 14days. Results of this study indicate that the cone essential oil of M. glyptostroboides might be a useful candidate for using in food industry to control the growth of pathogenic microorganisms.
