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.
SDS-electrophoresis of polypeptide chains of total protein fraction obtained from Spirulina cultivated in the presence of Cr(III) coordination compounds have been carried out. New bands with apparent molecular mass 60, 4 kDa and 66, 7 kDa have been detected in the presence of Cr(III) coordination compounds.
