The focus of this research is spectral shifting of light using phycocyanin solution extracted from the blue-green microalga Spirulina platensis in order to increase biomass productivity of the green microalga Chlorella sp. Also, lipid and chlorophyll content of the green alga was investigated. With regard to the shift of the spectrum with the phycocyanin solution, a double layer flat panel photobioreactor and two different spectral shifting strategies were used. In each strategy, the effect of two different concentrations of the solution was investigated. In the first strategy, the light passes through the chamber containing the solution and then enters the microalga culture chamber. In the second strategy, the light first enters the culture chamber and then enters the chamber containing phycocyanin pigment. The results showed that the use of phycocyanin pigment by both strategies increased the biomass productivity (P) and the specific growth rate (μ_max) with a significant difference compared to the control system; the increase in P for first strategy was up to about 69%. Moreover, the use of phycocyanin solution with a lower concentration had a greater effect on the increase of total chlorophyll content; however, the solution with a higher concentration was more successful in the production of cell lipid content. Using the phycocyanin solution as spectral converter in a double layer flat panel photobioreactor increased the biomass productivity and chlorophyll content.

这项研究的重点是使用从蓝绿色微藻螺旋藻提取的藻蓝蛋白溶液对光进行光谱移动，以提高绿色微藻小球藻的生物量生产力。sp。此外，还研究了绿藻的脂质和叶绿素含量。关于藻蓝蛋白溶液的光谱移动，使用了双层平板光生物反应器和两种不同的光谱移动策略。在每种策略中，研究了两种不同浓度溶液的效果。在第一种策略中，光穿过包含溶液的腔室，然后进入微藻培养腔室。在第二种策略中，光首先进入培养室，然后进入含有藻蓝蛋白色素的室。结果表明，由这两种策略的使用藻蓝蛋白颜料的增加的生物量产率（P）和所述比生长速率（μ_最大）与控制系统相比有重大差异；第一种策略的P值增加了约69％。此外，使用较低浓度的藻蓝蛋白溶液对增加总叶绿素含量有较大的影响。但是，浓度较高的溶液在产生细胞脂质方面更成功。在双层平板光生物反应器中使用藻蓝蛋白溶液作为光谱转换器可提高生物量生产力和叶绿素含量。
