【摘要】 [Objective] To optimize the culture condition of Spirulina platensis under industrialized condition and to compare the contents of nutritional componentsin spring. [Method] In the enclosed workshop with collecting light panel as the ceiling,S. platensis was cultured by photo bioreactors with four different opticalpaths. The maximum cell densities of photo bioreactors with different optical paths were compared as well as the contents of different nutritional components. [Result] The maximal cell density was 1. 52 g / L in 20 cm bioreactor. The contents of protein and phycocyanin were the highest in 20 cm light path,which were 61.2% and 10. 9% ,respectively. The contents of polysaccharides,crude fat and chlorophyll a were the maximum in 10 cm bioreactor,the content of crude fat reached 7. 48% ,the content of polysaccharides reached 8. 2% ,and the content of chlorophyll a reached 1. 3 mg / g. [Conclusion]This method optimized the culture condition of S. platensis under industrialized condition,which provided theoretical references for the development and utilization of S. platensis.
