Abstract
The invention is directed to a culture medium for Haematococcus that contains combustion gases like carbon dioxide, carbon monoxide, and oxides of nitrogen or sulfur and which fixes the carbon, nitrogen or sulfur in these combustion gases into biomass and to methods providing superior biomass yields using this culture medium to culture select species of Haematococcus such as Haematococcus sp. KAU-01.
Claims15
A method for producing biomass, comprising:
- culturing Haematococcus in a culture medium in the presence of at least one combustion gas and light, thereby producing biomass;
- wherein said culture medium comprises from:
- 187.50 to 562.50 mg/L NaNO3, 37.50 to 112.50 mg/L KNO3, 12.50 to 37.50 mg/L Ca(NO3)2, 27.50 to 82.50 mg/L Mg(NO3)2·6H2O, 22.50 to 67.50 mg/L K2HPO4, 20.00 to 60.00 mg/L KH2PO4, 5.00 to 15.00 mg/L K2SO4, 11.88 to 35.63 mg/L MgSO4·7H2O, 0.88 to 2.63 mg/L urea, 32.50 to 97.50 μl/L HNO3, 7.50 to 22.50 μl/L in H3PO4, and water;
- wherein said culturing comprises removing eicosapentaenoic acid (EPA) from the culture medium while retaining viable Haematococcus.
