The possibility of controlling the development of microbial communities was investigated on the
basis of experimentally determined requirements for basic nutrients in R, S, and M dissociants of
Pseudomonas
aeruginosa.
On media with the limitation conditions preset on the basis of the predictions of a mathematical
model, exhaustion of glucose was experimentally confirmed for all monocultures and mixed cultures, as well
as balanced consumption of glucose, nitrogen, and phosphorus by the R dissociant at the corresponding initial
medium composition. The experimentally determined composition of mixed cultures was found to conform to
the ones calculated using the mathematical model. The data obtained suggest the possibility of cyclic consumption
of phosphorus by
P. aeruginosa.
