Abstract:
The purpose of the research was to accumulate results proving the ability of biocenosis in natural water bodies and biological treatment facilities to maintain stability at nickel concentrations above the MPC up to 30% without reducing biomass growth. Studies have shown that microbial communities in the aquatic environment synchronize natural defense systems and are able to change the mechanisms of resistance. The complex formation of nickel with inorganic compounds and mixed-ligand complexes of conjugated bases of amino acids makes it possible to obtain three-dimensional spatial structures near the silt particle that bind nickel ions and thereby reduce its toxic effect.
