  • Patent number: 11560542
    Abstract: The invention relates to the cultivation of unicellular red algae (URA) for producing biomass for the production of products of interest, such as dry biomass or compounds or mixtures of compounds of interest extracted from the biomass produced, particularly food pigments or colouring agents. The invention more particularly relates to the industrial production of said biomass, which must satisfy an economic equilibrium of profitability, with both an increase in productivity (quantity of biomass and of compounds of interest in the biomass) and an economically acceptable production cost.

  • Publication number: 20220372428
    Abstract: The present invention relates to the field of culturing unicellular red algae (URA). The invention relates in particular to a method for culturing URA, characterised in that the culture medium includes milk permeate as the main contribution of at least one carbon source. The invention also relates to biomass which can be obtained by the method according to the invention, to the uses of said biomass and to the products that can include said biomass.

  • Patent number: 11162126
    Abstract: The invention relates to the field of alga culture, particularly the culture of unicellular red algae (URA). In particular, the invention relates to a method for the culture of unicellular red algae, characterized in that the specific culture conditions, in terms of lighting and nutrients, allow the production of a protein-rich biomass that can contain an increased amount of URA and produce, in addition to pigments, particularly phycocyanin and carotenoids: ?-carotene and zeaxanthin. The invention also relates to the biomass that can be produced using the method of the invention, to the uses of the biomass and to products that can contain said biomass.

  • Publication number: 20200239820
    Abstract: The present invention relates to a reactor including a tank (81) intended to contain a mass to be treated and at least one lighting and heating device (83) intended to promote the treatment of this mass, remarkable in that the lighting and heating device comprises: a plate including at least one groove extending longitudinally and composed of a bottom and two side walls, illumination means in thermal contact with the bottom of the groove, so that the heat generated by the illumination means is transmitted to the mass to be treated via the bottom of the plate.

  • Patent number: 10100340
    Abstract: A method for culturing a protist of the Aurantiochytrium mangrovei genus. The genus is characterized genetically and by virtue of the lipid profile thereof. The method makes it possible to obtain a high biomass yield and a lipid, and more particularly docosahexaenoic acid (DHA), enrichment of the protists thus cultured. The development of a culture medium allows the production, at high cell density, of a DHA-rich protest of the Aurantiochytrium mangrovei genus. The medium is chemically defined at low sodium ion (Na+) and chloride ion (Cl?) content.
