Device and method for producing photosynthetic microorganisms in a photobioreactor

Résumé

Device and method for the production of photosynthetic microorganisms in a photobioreactor The present invention relates to a photobioreactor device (1) comprising a culture chamber (2), containing a reaction medium (3) for growth of microorganisms, provided with at least one means for stirring said medium (3). Said device (1) comprises a closed loop (6), starting from said enclosure of said device (1), integrating an extraction pump (7) from the reaction medium (3) to an extraction unit (9) of the biomass (10) that comprises said loop, which unit (9) incorporates a means of separating part of the biomass (10) from the reaction medium (3) to obtain a clarified reaction medium (10a) which is returned in said enclosure (2). Said device (1) further comprises at least one measuring means (14, 14a) of the concentration of biomass or of photosynthetic activity in said reaction medium (3, 10), and a unit (15) for processing measurements and control capable of actuating said pump (7).
