Résumé

This paper examines the synergistic action of carbon dioxide and nisin on Listeria monocytogenes Scott A wild-type and nisin-resistant cells grown in broth at 4 °C. Carbon dioxide extended the lag phase and decreased the specific growth rate of both strains, but to a greater degree in the nisin-resistant cells. Wild-type cells grown in 100% CO2 were two to five times longer than cells grown in air. Nisin (2.5 µg/ml) did not decrease the viability of nisin-resistant cells but for wild-type cells caused an immediate 2-log reduction of viability when they were grown in air and a 4-log reduction when they were grown in 100% CO2.
