A model describing the effect of temperature history on lag time for Listeria monocytogenes.
A model was built to describe the influence of the temperature and the duration of pre-incubation on the lag time for regrowth of Listeria monocytogenes at low temperature. This model is consistent with the usual procedure used to calculate lag times of cultures growing under fluctuating temperatures. It also describes the effect of prolonged starvation conditions on the regrowth lag time and takes into account the influence of the physiological state of inocula in predictive models.
