[Motionless dissipative structures formed by soil bacteria].

A model of the stationary distribution of bacteria in soil, formed upon filtration of soil solution was constructed. The region of parameter values was determined at which the distribution is dissipative and has the form of alternating strips. Regularities in the degeneration of the dissipative structure as the parameters approach the boundary of the region were discovered. The analysis was made using qualitative, analytical and quantitative investigation of differential equations of the transfer. Data on the growth, nourishment, and death of copiotrophic bacteria were used in the calculations.
