title: [Synchronization of bacterial division in rapid change of tryptone concentration].
abstract: 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.
