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.
Claims6
A method for utilizing flue gas to produce biomass, comprising:
- (a) combusting a fossil fuel to form a flue gas comprising carbon dioxide and one or more of a nitrogen oxide, a sulfur oxide, and a volatile organic compound, and
- (b) culturing a Haematococcus sp. in a culture medium in contact with the flue gas and in the presence of light, thereby producing the 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 H3PO4, and freshwater.
