The aim of this study was to evaluatethe effects of different colored light emitting diodes (LEDs) on the growth, pigment yield, and photosynthetic performance of Arthrospira maxima, a commercially exploited species of cyanobacteria. The highest growth and chlorophyll a (Chl a) concentration were obtained under red LED and white fluorescent light, while the lowest growth and Chlaconcentration were observed under blue LED. However, blue LED produced the highest levels of phycobiliproteins (3.20 mg·gphycocyanin [PC]; 0.19 mg·g allophycocyanin [APC]; 0.97 mg·gfor phycoerythrin [PE], effective quantum yield (Φ) and maximum relative electron transport rate (rETR) inA. maxima. The results of this study suggest that red and blue LEDs increase the biomass yield and pigment content of cyanobacteria, respectively, and the combined use of red and blue light may significantly improve algal biomass and biopigment yield.
本研究旨在评估不同颜色发光二极管（LED）对商用蓝藻螺旋藻生长、色素产量和光合作用性能的影响。在红色 LED 和白色荧光灯下，藻体获得了最高的生长和叶绿素 a（Chl a）浓度，而在蓝色 LED 下，藻体的生长和 Chlaconcentration 最低。然而，蓝色 LED 产生了最高水平的藻胆蛋白（3.20mg·g 藻蓝蛋白 [PC]；0.19mg·g 别藻蓝蛋白 [APC]；0.97mg·g 藻红蛋白 [PE]）、有效量子产率（Φ）和最大相对电子传递率（rETR）。本研究结果表明，红色和蓝色 LED 分别增加了蓝藻的生物量产量和色素含量，而红蓝光的联合使用可能显著提高藻类生物量和生物色素产量。
