[The multidimensional character of the niches in Gause's law applicable to prokaryotes and the methods for the spatial separation of competing associates].

The multidimensional niche in Gause's law includes, with respect to prokaryotes, the following factors: the alimentary factor, the symbiosis-antagonism complex, the respiratory function, the concentration of associants, mobility. Cultivation in U-shaped tubes is the optimum method for the detection of spatial separation on account of such factors as respiration and mobility.
