[A mechanism of development of spatial-temporal orderliness in bacterial systems].
Peculiarities of the mechanism of intercellular regulation capable of initiating nonhomogeneous spatial structures in different experimental bacterial systems are analysed. A model of band formation of bacterial density in agar-stabilized bacterial system with opposite gradients of the substrate and oxygen is suggested. It is shown that for the appearance of spatial structures in the bacterial systems a time delay in the cell response to the external signal is of principal importance, as well as the hysteresis of transitions between differentiated bacterial states.
