Rapid decrease from 1 to 0.4% or rapid increase from 0.4 to 15 in tryptone concentration caused synchronization of cell division in a culture of Escherichia coli. The effect was not observed for the mutants impaired in reception of taxis system AW-569 and AW-618. Maintenance of the constant concentration of serine prior to and after alteration in tryptone concentration prevented synchronization in wild-type strains J621 and AW-405. Based on the results obtained, it was inferred that reception of the change in the concentration of the substrates-attractants is necessary for synchronization of bacterial cell division this way.
胰蛋白胨浓度从1%迅速降至0.4%或从0.4%迅速升至15%会导致大肠杆菌培养物中细胞分裂同步。在趋化系统AW - 569和AW - 618接收功能受损的突变体中未观察到这种效应。在胰蛋白胨浓度改变之前和之后维持丝氨酸浓度恒定可防止野生型菌株J621和AW - 405出现同步。根据所得结果推断，以这种方式实现细菌细胞分裂同步，底物 - 引诱剂浓度变化的接收是必要的。
