Division times for the two subpopulations of fast- and slow-growers in Sample A batches from the three wild-type strains.

Fast-growers typically have a division time ranging from 7 to 11 hours, depending on the strain, while slow-growers have much longer division times ranging from 12h to 17h. Division times for slow-growers of the WT 11+ strain could not be calculated, as they were only at the beginning of their exponential phase (N.D.: not determinable).Division times for the two subpopulations of fast- and slow-growers in Sample A batches from the three wild-type strains.
