The productivity of cyanobacteria Spirulina platensisat the cultivation in presence of coordinative compound of Cu(II) havs been determined. The spirulina productivity depends on coordination compounds nature and concentrations. Coordinative compounds: [Cu(L1-H)H2O(NO3)], CuL32(NO3)2 and CuL(NO3)2 had the most favorable effect for biomass accumulation
