A photobioreactor includes one or more annular chambers concentrically positioned about a central axis, and an algae slurry contained within the one or more annular chambers.

An algae cultivation system may include: a plurality of panels within a cultivation container, positioned along a first axis perpendicular to the gravitational force, wherein a cultivation volume is created between each pair of panels, and wherein the cultivation volumes are fluidly coupled so as to allow horizontal flow therebetween along the first axis; at least one first sparger, to distribute a first fluid into the container at a first operating flow rate; at least one second sparger, to distribute a second fluid into the container at a second operating flow rate; and at least one controller, to control the first operating flow rate and the second operating flow rate. The first operating flow rate may be adapted to allow turbulent mixing the algae in the cultivation container, and the second operating flow rate may be adapted to allow assimilation of materials in a liquid in the cultivation container.

A deepwater photobioreactor system including a vertical stack extending between an ocean surface and an ocean floor. The vertical stack includes an inlet conduit and an outlet conduit where the inlet conduit is arranged to transport at least seawater and the outlet conduit is arranged to transport at least a biomass. The system includes a first photobioreactor in fluid communication with the inlet conduit and the outlet conduit that is connected to the vertical stack via the inlet and outlet conduits at a first position along the vertical stack below the ocean surface.

The system also includes a mooring system arranged to anchor the vertical stack to the ocean floor and arranged to receive the biomass via the outlet conduit and output the biomass to a harvest pipeline.

The present invention relates to a reactor comprising a vessel (1) for containing: • a mass to be treated, and • at least one lighting device (2a, 2b) intended to promote the treatment of said mass, characterized in that each lighting device (2a, 2b) comprises a light diffuser including at least one micro-etched plate (211) which is transparent to light radiation.

The technology disclosed herein relates to, at least in part, a removable imaging cassette. An illumination plate is configured to transmit light. A cassette body defines an outer surface and a cassette cavity within the outer surface, where the outer surface surrounds the illumination plate. The cassette cavity abuts the illumination plate. A light source is disposed in the cassette cavity. Mating electrical contacts extend through the outer surface of the cassette body, where the mating electrical contacts are operably coupled to the light source.

The present disclosure provides methods and materials for the cultivation and/or propagation of a photosynthetic organism. Such methods may comprise the use of a lamp assembly that comprises a plurality of circuit boards, each comprising at least three edges, arranged in a substantially spherical shape defining an interior lamp assembly volume, wherein the plurality of circuit boards comprise a first planar surface in contact with the interior lamp assembly volume and an opposing second planar surface comprising light emitting diodes (LEDs); and a barrier that surrounds the plurality of circuit boards forming the substantially spherical shape.

The present invention relates to the field of stem cells. More specifically, the present invention provides compositions and methods for using optogenetics to sustain the pluripotency of stem cells. In one embodiment, a vector comprises a nucleotide sequencing encoding a fusion protein comprising the intracellular domain of fibroblast growth factor 1 receptor (FGFR1) and a photoactivatable domain.

A photobioreactor is particularly suited for producing micro-organisms such as microalgae. The photobioreactor is a closed reactor with reactor vessels which have an open top that is closed by a top wall of the photobioreactor and in which a nutrient medium can be held. At least some of the reactor vessels are individual vessels. Adjacent reactor vessels form a gap between a front wall and a rear wall, the gap being closed at the top side by an overflow wall region and having a vessel overflow opening between the adjacent reactor vessels. A lighting element is held in the gap. Each of the reactor vessels has a partition which divides the reactor vessel into a front reactor chamber and a rear reactor chamber. At least one partition through-flow opening between the front and rear reactor chambers is formed in the partition close to the bottom wall.

A compound algae culture apparatus is provided, which includes a photobioreactor module, a growth regulating module, a circulation transfer module, and a circulation pipeline module. The photobioreactor module includes at least one photobioreactor unit, and the growth regulating module includes at least one growth tank unit. The photobioreactor unit includes a light-transmitting coiled pipe. The growth tank unit has a tank body, and a plurality of partitions are disposed in the tank body to divide an inside of the tank body for formation of a curved flow channel A culture fluid for culturing algae passes through the photobioreactor unit and enters the growth tank unit. A volume of the growth tank unit is larger than a volume of the photobioreactor unit, and a residence time of the culture fluid in the growth tank unit is greater than a residence time of the culture fluid in the photobioreactor unit.
