ABSTRACT. The development of the mining industry and non-ferrous metallurgy is one of the main factors of anthropogenic pollution of the environment by various chemical pollutants. One of the possible and most promising direction for solving the problem of environmental pollution and biocenoses, in particular with heavy metals, is the use of physiological adaptive mechanisms of tolerance and biosorption of saprotrophic microflora. A high level of inhibitory action of the investigated essential elements was established when creating a massive cationic load on the studied microorganisms of the genus Bacillus with a high level of sorption of copper and cobalt on the surface structures of bacterial cells.

KEYWORDS: bioaccumulation, copper, cobalt, diffusion, atomic force microscopy.
