Antimicrobial activity of nisin incorporated in pectin and polylactic acid composite films against Listeria monocytogenes
An extruded composite food packaging film containing pectin, polylactic acids (PLAs) and nisin was developed to inhibit Listeria monocytogenes. The mechanical properties and surface structure of the film were also examined. Cells of L. monocytogenes were reduced by 2.1, 4.5 and 3.7 log units mL by the pectin plus PLA (pectin ⁄PLA) film containing nisin (1000 IU mL of tested liquid) in Brain Hea...
متن کاملSynergistic effects of nisin and thymol on antimicrobial activities in Listeria monocytogenes and Bacillus subtilis.
Nisin Z and thymol were tested, alone and in combination, for antibacterial activity against Listeria monocytogenes ATCC 7644 and Bacillus subtilis ATCC 33712. The antibacterial effect of nisin Z, produced by Lactococcus lactis KE3 isolated from the traditional Moroccan fermented milk, was greatly potentiated by sub-inhibitory concentrations of thymol in both bacterial strains. Our data showed ...
متن کاملSensitivity 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 کاملInfluence of nisin and selected meat additives on the antimicrobial effect of ovotransferrin against Listeria monocytogenes.
The objective of this study was to determine the effect of nisin and selected meat additives (salt, lactate, lactate-diacetate combination, and polyphosphate) on the antimicrobial activities of ovotransferrin (OTF) against the growth of Listeria monocytogenes. A Bioscreen C turbidometer (Oy Growth Curves AB Ltd., Helsinki, Finland) was used to evaluate the effect of various concentrations of ni...
متن کاملNisin, Carvacrol and Their Combinations Against the Growth of Heat-Treated Listeria monocytogenes Cells
Listeria monocytogenes is a Gram-positive microorganism responsible for one of the most serious food-borne diseases in the world, listeriosis. The aim of this study is to evaluate the combined effect of a heat pretreatment with the use of antimicrobials, nisin and carvacrol, on the growth of L. monocytogenes, and their potential uses as food preservatives. Carvacrol showed a dose-dependent inhi...
