Rezumat

The growth of Spirulina platensis biomass in synthetic copper-containing effluents with different chemical composition in order to obtain renewable biosorbent was studied. Metal uptake by biomass was traced using neutron activation analysis. Biomass survival ability was strongly dependent on metal ions concentration and chemical composition of the effluents. At higher metal ions concentrations (Cu -10mg/L, Fe-5mg/L, Ni – 2mg/L and Zn- 2mg/L) biomass was able to grow only for one cycle, while reducing metal concentration (up to Cu – 2.5mg/L, Fe-1.25mg/L, Ni – 0.5mg/L and Zn- 0.5mg/L) the number of cycles increased. The effect of metals ions on biomass productivity and its main components content: proteins, carbohydrates, lipids, phycobilins and beta-carotene was assessed. The decrease of productivity as well as proteins, phycobilins and beta-carotene in varying degrees was noticed in all studied systems. Content of carbohydrates decreased at high metal ions concentration in all studied systems, while their increase was observed with reduction of metal concentration. Lipids were less affected by presence of metal ions in the cultivation medium. Spirulina platensis can be considered as renewable biosorbent for diluted effluents or wastewater post-treatment.
