dc.description.abstract | Photosynthetic pigments from microalgae have great potential biotechnological applications, as healthy food colorants and
cosmetics. The production of photosynthetic pigments depends on many environmental conditions, mainly light intensity during
the cultivation period. The present study aimed to determine the productivity of photosynthetic pigments in the biomass of
S. platensis, including total chlorophylls, carotenoids, and phycocyanin, under different light intensities: 40 µmol m–2 s
–1
(lower light
intensity) and 70 µmol m–2 s
–1
(higher light intensity). The results showed that S. platensis culture responds to changes in light intensity
by changing the composition of photosynthetic pigments as an adaptive mechanism. The higher carotenoids content (69.69 ± 7.47
µg/g dw) was found under high light intensity, meanwhile, the higher chlorophyll (1495.47 ± 279.00 µg/g dw) and phycocyanin
(4995.49 ± 576.52 µg/g dw) contents were observed under low light intensity. The highest productivity of photosynthetic pigments
in S. platensis was shown by phycocyanin (318.86 ± 44.22 µg/L/day) and cholophylls (95.38 ± 19.35 µg/L/day) which were produced
under low light intensity. Our results show that changes in light intensity can contribute to a stronger effect on the productivity of
algal pigments for human health benefits and food colorants. | en_US |
