title: [The process of bacterial population splitting into dissociants and long-term batch cultivation of bacteria].
abstract: The growth and composition of a population were studied during long-term (up to 50 days) batch cultivation of mono and mixed cultures of Pseudomonas aeruginosa S- and M-dissociants and Rhodobacter sphaeroides R- and M-dissociants without the addition of nutrients. During the cultivation of P. aeruginosa on a glucose-containing mineral medium, periodic lysis followed by polyculture growth resumption in the late stationary phase occurred on account of the M-dissociant: the change in its cell number corresponded to the change in the total cell number of the association. It was shown that the periodic occurrence of reducing sugars in the medium preceded the resumption ofpolyculture growth.
