RESUMO

The full factorial experimental design used for optimization of the nutrient medium composition for cultivating Spirulina platensis Geitl. Optimization was carried out. The introduction into the medium of selenium (Na2SeO3), germanium (GeO2), and iodine (KI) considerably improved the nutritive value of the biomass. Productivity on the optimized medium made up 1.55-1.60 g/L for six days of cultivation.
