Thermal inactivation, growth, and survival studies of Listeria monocytogenes strains belonging to three distinct genotypic lineages.

Abstract excerpt

Twenty-one Listeria monocytogenes strains belonging to three different genotypic lineages were evaluated for differences between lineages and between individual strains with respect to thermal inactivation, growth, and survival. Three sets of heat inactivation conditions (60 degrees C, pH 6.0, and 0.5 M lactate; 55 degrees C, pH 6.0, and 0.5 M lactate; and 50 degrees C, pH 4.0, and 0.5 M lactate) were used on...
