Fig. 1

The model of Baranyi and Roberts incorporates three stages of bacterial growth. An illustration of the three stages of bacterial growth (lag, exponential and stationary) described in the model of Baranyi and Roberts [2, 3] (solid blue line). Other classical models for the population size, x(t), incorporate only the exponential and stationary phases (black dashed line) on the logarithmic scale. The top panel shows how the specific growth rate changes with the logarithm of the cell concentration during the three stages, whilst the bottom panel demonstrates how these phases correspond to the familiar sigmoidal shape that is observed when plotting the log cell concentration over time
