AIMS: Listeria monocytogenes ΔgadD1 and ΔlisK mutants display enhanced and reduced sensitivity, respectively, to the food preservative nisin in laboratory media. However, the behaviour of these strains in a nisin-containing food has not been assessed. Here we use cottage cheese as a model food to address this issue. MATERIALS AND RESULTS: Antibiotic-resistant forms of the wild-type and mutant strains were...
