WitrynaListeriosis usually results from infection by Listeria monocytogenes, a Gram positive rod. L. monocytogenes is relatively resistant to freezing, drying and heat. It will grow at temperatures from 1°C to 45°C and can proliferate at refrigeration temperatures on contaminated foods. It can tolerate a pH from 3.6 to 9.5, Joseph Lister, and more. WitrynaThe synergistic effect of heat‐treatment (55 °C) and nisin (500 IU ml−1) on the Nisr cells and the WT L. monocytogenes Scott A was also studied. When the cells were grown in the absence of nisin, there was no significant (α = 0·05) difference in heat resistance between WT and Nisr cells of L. monocytogenes at 55, 60 and 65 °C.
