Sensitivity of nisin-resistant Listeria monocytogenes to heat and the synergistic action of heat and nisin.
Nisin, a bacteriocin produced by some strains of Lactococcus lactis, acts against foodborne pathogen Listeria monocytogenes. A single exposure of cells to nisin can generate nisin-resistant (Nisr) mutants, which may compromise the use of nisin in the food industry. The objective of this research was to compare the heat resistance of Nisr and wild type (WT) Listeria monocytogenes. The synergisti...
متن کاملBioenergetic mechanism for nisin resistance, induced by the acid tolerance response of Listeria monocytogenes.
This study examined the bioenergetics of Listeria monocytogenes, induced to an acid tolerance response (ATR). Changes in bioenergetic parameters were consistent with the increased resistance of ATR-induced (ATR(+)) cells to the antimicrobial peptide nisin. These changes may also explain the increased resistance of L. monocytogenes to other lethal factors. ATR(+) cells had lower transmembrane pH...
متن کاملinhibition effect of lactic acid bacteria against food born pathogen, listeria monocytogenes
in recent years due to changes in lifestyle and eating behavior of the human populations, disease caused by contaminated food has increased significantly. listeria monocytogenes, escherichia coli o157:h7 and salmonella enteric are three of the most important food borne bacterial pathogens and can lead to food borne diseases. also today wide spread of resistance to antibiotics among bacteria occ...
متن کاملSalmonella typhimurium and Listeria monocytogenes Growth Inhibition by Zataria multiflora Essential Oil in Ground Meat
Background: Zataria multiflora boiss is a member of Lamiaceae family with antibacterial, antifungal, and antioxidant activity. The aim of this study was to evaluate chemical composition and antibacterial effect of Zataria multiflora essential oil against two foodborne pathogens in meat. Methods: The inhibitory effect of Zataria multiflora essential oil (Minimum inhibitory concentration and Min...
متن کاملThe synergistic effect of nisin and lactoferrin on the inhibition of Listeria monocytogenes and Escherichia coli O157:H7.
AIMS The goal of this study was to determine whether nisin and lactoferrin would act synergistically to inhibit the growth of Listeria monocytogenes and Escherichia coli O157:H7. METHODS AND RESULTS Lactoferrin and nisin separately or in combination were suspended in peptone yeast glucose broth and following inoculation with L. monocytogenes or E. coli O157:H7 growth inhibition of each pathog...
