ABSTRACT:
The process consists of culturing in a closed photobioreactor (2) microalgae suspended in a culture medium (1), the oxygen produced by the microalgae by photosynthesis being collected and then reinjected into the culture medium, separating (6) the microalgae from the culture medium (1), dissolving (12) the microalgae, grinding or crushing (14) the solution of microalgae, adding (16) a solvent to the ground or crushed solution for solubilizing the antioxidants produced by the microalgae and then separating (18) the liquid phases present.
