FIELD: phytobiotechnology, microbiology, medicine, food processing industry.
SUBSTANCE: method for preparing zinc-enriched spirulina biomass (Spirulina platensis) involves by simultaneous addition of zinc nitrate or sulfate in the concentration 10-30 mg/l and seeding inoculum in the concentration 0.1-0.3 mg of dry mass/l to the cultural medium. Method provides preparing spirulina biomass in the concentration 3.3-4.30 mg/g of dry mass and the yield of biomass 2.5-3.6 g/l for short period (4-5 days of cultivation).
EFFECT: improved preparing method.
