The invention relates to a device (10) for producing microalgae, comprising a basin (12) containing an aqueous medium and a movable support (14) capable of receiving a cell culture made up of algae cells, which movable support is immersed at least partially in the aqueous medium and has at least a first portion and a second portion, characterised in that the movable support is arranged in the basin such that the first portion is exposed directly to a main light source (18) and forms an exposure section (24), and the second portion is not exposed directly to the main light source (18) and forms an inhibition section (26), the device (10) further comprising a secondary light source (28) designed to emit actinic light in the direction of the inhibition section (26) so as to inhibit the pigment synthesis of at least some of the algae cells. The invention also concerns a method for producing microalagae.
Device for producing microalgae, including a basin containing an aqueous medium and a movable support capable of receiving a cell culture made up of algae cells, said movable support is immersed at least partially in the aqueous medium and has at least a first portion and a second portion, characterised in that the movable support is arranged in the basin such that the first portion is directly exposed to a main light source and forms an exposure section, and the second portion is not directly exposed to the main light source and forms an inhibition section, the device further comprising a secondary light source designed to emit actinic light in the direction of the inhibition section so as to inhibit the pigment synthesis of at least some of said algae cells.
Method for producing microalgae, comprising the successive exposure of a cell culture made up of algae cells, with phases of direct exposure to an incident main light and phases in the shade of said incident main light, characterised in that the cell culture is also exposed to actinic light during at least some of the phases in the shade of said incident main light so as to inhibit pigment synthesis and render at least some of the algae cells transparent.
