  • Bioreactor for microalgae
    Patent number: 10711232
    Abstract: The invention relates to a bioreactor comprising a tank containing a culture medium in which a cell culture composed of algae cells is dispersed. The cell culture of algae has a concentration greater than 0.1 g/L in the culture medium, and each algal cell has a minimum absorption in a specific range of wavelengths of light. The bioreactor comprises a light source that is capable of emitting incident light in the direction of the tank, 60% of the photons of the incident light having a wavelength which is included in said specific range of wavelengths of light. The invention also relates to the use of the bioreactor for the production of biomass.
    Type: Grant

  • Method and unit for producing microalgae
    Patent number: 10106765
    Abstract: The invention relates to a method for producing microalgae on a support (14) that is movably mounted essentially in an aqueous medium contained in a tank (12), said method comprising a succession of phases in which the microalgae developing on the support (14) are exposed to sunlight and phases in the shade, the light intensity received in the shade being less than 50% of the average light intensity received during the sunlight exposure phases. The total length of the shade phases is more than 50% longer than the total length of the sunlight exposure phases.
