ABSTRACT:
A system and method for its use for efficiently culturing algae such as Spirulina are provided. The system comprises a culture pool for exposing a culture fluid containing the algae to sunlight, a culture tank having a larger depth than the culture pool, which is disposed adjacent to the culture pool, a supply unit for supplying the culture fluid from the culture pool to the culture tank, and at least one filter for removing grown algae from the culture fluid overflowing from the culture tank to the culture pool, while allowing to return a filtrate containing immature algae to the culture pool. It is preferred that this system further comprises a unit for mixing a gas containing carbon dioxide in the culture fluid to be supplied in the culture tank, and a lighting unit disposed in the culture tank to provide an artificial light to the culture fluid. In this case, it is possible to carry out the photosynthesis of the algae night and day.
