Abstract  

Abstract [Objective] The purpose of this paper was to investigate the effects of mixing intensity on the alga growth. [Method] Spirulina platensis was cultured in the flat plate photo-bioreactors both indoors and outdoors, the alga growth areal yield and chlorophyll content under different mixing intensity were measured. [Result] Results showed that the alga growth yield increased with the mixing intensity increasing; the physiological characteristic was not influenced by the mixing intensity when the alga was cultured indoors, while it was influenced by the mixing under the outdoor condition. [Conclusion] To intensify the culture liquor mixing can effectively enhance the alga yield.
