[Kinetic analysis of behavior of chemotactic bacterial population at the interface of two media].
The behavior of a population of bacteria at the boundary with a chemotactically active water medium containing the sites of specific binding to cell receptors was analyzed. A kinetic model of chemotaxis was used for the analysis. Differences in the behavior of strains metabolizing and not metabolizing the substrate were revealed. Six phases of interface taxis were distinguished and characterized. The results of the analysis were confirmed by the densitometric data.
