1. A method for culturing algae, the method comprising:

  • culturing alkaliphilic algae in an open pond medium having a pH above 9.5, sufficient to allow increased fixation of atmospheric CO2 into the open pond medium; and

    incorporating into the open pond medium an inorganic carbon buffer, wherein the inorganic carbon buffer comprises HCO3

    present at a concentration ranging from 4.5 mM to 60 mM and the open pond medium has a salinity in the range of from about 10 g/L to about 30 g/L and an alkalinity of up to about 1 M;

    wherein the open pond medium is free of any concentrated supply of CO2, and no concentrated source of CO2 is used to supply carbon for culturing the alkaliphilic algae.
