First appearance time and duration of persistence of asymmetric divisions. The time of appearance of the first asymmetric divider in the newly inoculated cultures (hollow bars) and the duration of persistence of asymmetric divisions after the appearance of the first asymmetric divider (filled bars) were noted for cells maintained in the Erd-Schreiber soil extract cultures with one of three different bacterial concentrations. Appearance time of first asymmetric dividers and persistence time of asymmetric divisions were analyzed independently. Error bars: standard error. Levels not connected by the same letter are significantly different (P < 0.05).
