A closed-loop system for growing algae in a bioreactor is disclosed, for example, to produce biofuel. An aqueous bioreactor solution is formulated such that the principal source of carbon for algae growth is supplied by sodium bicarbonate. During algae growth in the aqueous solution, the concentration of sodium bicarbonate in the solution is reduced while the concentration of sodium carbonate increases. A regenerator is provided to regenerate sodium bicarbonate from the sodium carbonate. Specifically, after sufficient growth, the algae are concentrated and an algae depleted media is produced. Carbon dioxide is then introduced into the algae depleted media to regenerate sodium bicarbonate from the sodium carbonate. The regenerated sodium bicarbonate is then recycled into the bioreactor to supply carbon for further algae growth.
