The acumulation of copper in biomass of cyanobacteria Spirulina platensis CNM - CB – 02 at the cultivation in the presence of coordination compounds of Cu (II) has been determined. Bioaccumulation of copper depends on the nature of ligands of the compounds. It was established that compounds [CuL2(Sfz)3H2O] and [Cu(L-2H)] contribute to the increasing of copper content in the biomass of spirulina in 2,94 – 3,42 times compared to the reference sample.
The action of some coordinative compounds of Cr(III) on Spirulina strain growth and development has been studied. High stimulation action of K2[Cr(NTA)(C2O4)(H2O)]·2H2O and [K2Cr2(SO4)4]·12H2O on Spirulina productivity has been established.
