Light-emitting diodes (LED) can be utilized as tailorable artificial light sources for the cultivation of cyanobacteria such as Arthrospira platensis (AP). To study the influence of different LED light colors on phototrophic growth and biomass composition, AP was cultured in closed bioreactors and exposed to red, green, blue, or white LED lights. The illumination with red LED light resulted in the highest cell growth and highest cell densities compared to all other light sources (order of cell densities: red > white > green > blue LED light). In contrast, the highest phycocyanin concentrations were found when AP was cultured under blue LED light (e.g., order of concentrations: blue > white > red > green LED light). LED-blue light stimulated the accumulation of nitrogen compounds in the form of phycobiliproteins at the expense of cell growth. The results of the study revealed that exposure to different LED light colors can improve the quality and quantity of the biomass gained in AP cultures.
发光二极管（LED）可作为可定制的人工光源用于培养诸如钝顶螺旋藻（AP）等蓝细菌。为研究不同LED光颜色对光合生长和生物质组成的影响，将AP培养于封闭生物反应器中，并使其暴露于红色、绿色、蓝色或白色LED光下。与所有其他光源相比，红色LED光照导致细胞生长最快且细胞密度最高（细胞密度顺序：红色>白色>绿色>蓝色LED光）。相反，当AP在蓝色LED光下培养时，藻蓝蛋白浓度最高（例如，浓度顺序：蓝色>白色>红色>绿色LED光）。蓝色LED光以细胞生长为代价刺激了藻胆蛋白形式的氮化合物积累。该研究结果表明，暴露于不同LED光颜色可提高AP培养物中所获生物质的质量和数量。
