The objective of the project is to design an LED illumination system optimized for the accumulation of high-value lipids enriched with stable isotopes during the growth of microalgae. The lighting system makes it possible to select wavelengths and adjust them so as to influence the quantity and quality of the biomass produced by favoring the production of certain biomolecules. Iso-Biokem aims to increase the production of certain lipids and sugars of higher value by knowing the optimal lighting conditions.
