Biphasic inactivation of all culturable (---) and healthy culturable (-·-) cells as described by (a) the independent models and (c) the sublethal injury model that are constructed with the model of Cerf [50]. Based on these modelling results, the evolution of the sublethally injured population (···) and the percentage sublethal injury (—, (b,d) are calculated. The data are based on counts of culturable (x) and healthy (o) cells on non-selective and selective media as published by Noriega et al. [12]. The data were obtained by heat-treating low-density colonies of Listeria innocua at 54 °C (Dataset 2).
