Previous studies showed that light quality affects the morphogenesis of phototrophic microorganisms, growth rate, and biosynthesis.
The active spectra of PAR can be efficiently utilized, and the Photosynthetic Efficiency (PE) can be regulated to optimal levels by manipulating the spectral distribution and the intensity of light perceives by microorganisms.
Therefore, it is important to study the effects of different light qualities in order to identify the most efficient ones. Among artificial lighting systems, Light-Emitting Diodes (LEDs) allows to easy manage the main light qualities (PPFD and emission spectrum) and has the potential to be used.
Therefore, in this study, Arthrospira platensis F&M-C256 was cultivated in Internally illuminated PhotoBioReactors (IlPBRs) under LEDs lamps emitting red, blue, purple and white with the aim to investigate the effects of different light quality on the growth, biosynthesis and energy utilization efficiency.
