title: Effect of various environmental parameters on the recovery of sublethally salt-damaged and acid-damaged Listeria monocytogenes.
abstract: The influence of supplementing the culture medium with magnesium sulphate, D-glucose, L-cysteine, catalase or lithium chloride, of incubation temperature and of oxygen availability on the recovery of salt- or acid-damaged Listeria monocytogenes, was studied on a solid repair medium according to a Hadamard matrix, with seven parameters varying between a high and a low level. The most important factors for repair of stressed Listeria were further studied with complete factorial design experiments. Results show that conditions promoting resuscitation of acid- or salt-injured cells are stress-specific, and differ in part from those described in the literature for heat-stressed Listeria.
