Résumé: The distributions of the times to turbidity for wells inoculated with single cells of Listeria innocua were determined in different environmental conditions (pH 4.5 to 7 and with 0.5% to 8% of NaCl at 30 degreeC). It was established by statistical analysis that the main source of the variability of the detection times, T, is the variability of individual lag times. A linear relation dev(T) apprx T was observed between the detection times and their standard deviation. At slow growth, other sources of variability became increasingly significant.   http://dx.doi.org/10.1016/j.mimet.2003.08.006
