METHOD OF VANADIUM-ENRICHED SPIRULINA PREPARING Russian patent published in 2003 - IPC

FIELD: food and microbiological industry. SUBSTANCE: method involves culturing spirulina strain in medium containing sources of nitrogen, carbon, phosphorus, trace elements, in part, in Zarruck medium in the presence of vanadium salt taken among the group: sodium vanadate, vanadium nitrate, vanadyl sulfate taken in the concentration 100-200 mg/l. It is advisably to add vanadium salt in the process of medium preparing or at exponential growth stage in cells concentration 1 g/l of ACB, not less, or at stationary growth stage in cells concentration 2 g/l of ACB, nor less, or by batch addition at exponential stage of spirulina growth. The obtained spirulina biomass contains 250-2050 mcg of vanadium/g of biomass in organic form. Spirulina biomass is used as raw for fodder, food and pharmaceutical industries. Invention can be used for preparing nutrient supplements with biological activity. EFFECT: improved method of preparing, valuable properties of spirulina. 5 cl, 7 ex
