Process for the production and the extraction of antioxidants from a culture of microorganisms and a photobioreactor for performing this process.
This process consists in culturing in a closed photobioreactor (2) microalgae in suspension in a culture medium (1), the oxygen produced by the microalgae by photosynthesis being collected and then reinjected into the culture medium, in separating (6) the microalgae from the culture medium (1), dissolving (12) the microalgae, in milling (14) the solution of microalgae, in adding (16) a solvent to the milled solution to solubilise the antioxidants produced by the microalgae and then in separating (18) the liquid phases present.
