METHOD OF GROWING MICROALGA PORPHYRIDIUM PURPUREUM Russian patent published in 2018 - IPC C12N1/00 

FIELD: biotechnology.

SUBSTANCE: invention relates to biotechnology. Invention is a method comprising cultivating a culture of P. purpureum at a twenty-four-hour surface illumination of 13 kL, temperature 26–28 °C, the air purging rate of 1.25 liters per liter of culture per minute, with continuous bubbling of the culture carried out by spraying through an aquarium air diffuser in the medium according to Trenckensch, having a composition of NaNO₃ – 1.2 g⋅l^-1, NaH₂PO₄ × 2H₂O – 0.45 g⋅l^-1, Na₂EDTA – 0.037 g⋅l^-1, FeC₆H₅O₇ × 7H₂O – 0.0265 g⋅l^-1, MnCl₂ × 4H₂O – 0.0040 g⋅l^-1, CoCl₂ × 6H₂O – 0.0031 g⋅l^-1, (NH₄)₆Mo₇O₂₄ × 4H₂O – 0.0009 g⋅l^-1, K₂Cr₂(SO₄)₄ × 24H₂O – 0.0017 g⋅l^-1. Invention allows to increase biomass yield in the storage mode by 2.7 times in comparison with the prototype.

EFFECT: invention makes it possible to increase the yield of biomass in a cumulative regime.
