Abstract：Objective To study the effects of red and blue LED light on growth and material synthesis of Spirulina.Methods Spirulina platensis was cultivated under six ratio of red and blue LED mixture light,measuring and analysing the filaments morphology,growth index,photosynthetic pigments composition and oxygen-releasing capacity.Results Compared with the red light,the mixture light with low doses of blue light induced the length of the filaments to grow shorter,while diminished the screw tightening degrees.Furthermore,it increased the content of chlorophyll a,carotenoid and phycocyanobilin,promoted the growth of spirulina and substance accumulation,as well as enhanced the oxygen-releasing capacity.Conclusion 8R2B is the efficient light quality that can promote the growth and photosynthetic oxygen of spirulina markedly.
