The optimal time to harvest spirulina biomass for phycocyanin extraction was established. The phycocyanin yield and purity depend on used extracting solution, recording the maximum values for 1% CaCl2 solution in 10% alcohol. The testing for antioxidant activity of phycocyanin preparations by ABTS+ was carried out for both: preparations obtained from spirulina biomass grown on Zarrouk medium, as well as those obtained from biomass cultivated on medium enriched with germanium. The antioxidant activity of containing germanium phycocyanin preparations was the highest.
