Study of phycocyanin production from Spirulina platensis under different light spectra

ABSTRACT

The aim of this work was to investigate the production of phycocyanin by Spirulina platensis under different spectra of light. The dependent variables evaluated were the amount of phycocyanin obtained and its purity, demonstrating that there might be a restructuring of phycobilisomes, especially when the culture was subjected to red light, which increased the purity level up to 33 percent with a reduction of 16 percent in phycocyanin content, but with higher photosynthetic efficiency compared to natural light.
