1. A method for culturing algae, the method comprising:
- culturing alkaliphilic algae in an open pond medium having a pH above 9.5; and
incorporating into the open pond medium an inorganic carbon buffer sufficient to allow increased fixation of atmospheric CO2 into the open pond medium;
wherein the open pond medium is free of any concentrated supply of CO2, and no concentrated source of CO2 is used to supply carbon into the open pond medium.
