title: Synergistic effect of nisin and garlic shoot juice against Listeria monocytogenes in milk.
abstract: The aim of this research was to determine the synergistic effect of nisin and garlic shoot juice (GSJ) against Listeria monocytogenes ATCC 19118 found in whole (3.5%), low (1%) and skim (no fat content) milk. Garlic shoot juice (GSJ) at concentrations of 2.5%, 5% and 10% revealed strong and similar patterns of antilisterial effect against L. monocytogenes ATCC 19118 in all categories of milk. Nisin only at concentrations of 62.5, 125, 250 and 500IU/ml displayed a strong antilisterial effect as compared to the control group. Also, the synergistic combinations of GSJ (2.5%, 5%) and nisin (62.5, 125, 250 and 500IU/ml) had a remarkable antilisterial activity in all categories of whole, low and skim milk after 14 days. Results of this study indicated the synergistic effect of GSJ and nisin as a potential antilisterial agent for the food industry.
