An Axial Dispersion Bioreactor (ADBR) is designed for the photoautotrophic, mixotrophic or heterotrophic growth and production of microalgae and other microorganisms (bacteria, fungi, etc.) as well as cell cultures of plants, animals, insects and others. The ADBR is equipped with a plate having a plurality of holes that moves longitudinally or axially within the bioreactor to effect superior hydrodynamic and mixing patterns. The ADBR has the advantages of providing a low-shear culture environment, superior liquid mixing, and efficient gas mass transfer.

US_2020323241_A1

Absstract of: US2020315214A1

A new alga having an improved ability to produce a pigment is disclosed. When the new alga is used, a carotenoid-based pigment, specifically, a xanthophyll can be produced by consuming less energy, so that it is possible to efficiently produce the pigment at the industrial level. The pigment can be applied as a raw material for a food, a health functional food and a medicine, which include the pigment. Since a DNA fragment is not likely to be inserted into a target base sequence or a base sequence other than the target, it is expected that the procedure of constructing the mutant is not regulated as a GMO, so that it is expected that the procedure of constructing the mutant can create a big economic effect in terms of an industry which produces lutein and zeaxanthin by using microalgae.

CA_3088849_A1

Absstract of: AU2018380016A1

At least one elongated photobioreactor, at a small angle relative to horizontal and mixed substantially or entirely by large bubble flow, is used for contained cell culture, e.g., microalgae cultivation. Elongated, flexible, transparent, polymeric photobioreactor tubes, in near-grade and near-horizontal (e.g. sloped 1 degree to 3 degrees) orientation, and use of low-pressure air mixing, allow very inexpensive construction and operation. Multiple elongated tubes may be used for an independent operation of the multiple photobioreactor tubes for the same or different cells, e.g., microalgae and different applications. Low-pressure air is delivered near the low end of the bioreactor at less than 10 psig and without sparging, to produce large air bubbles that travel from the low end to the high end of the bioreactor, for turbulent mixing and gas exchange. Each inexpensive, flexible bioreactor tube is easily modified to improve internal flow characteristics and suspension of cells, and/or to include sensor and/or sampling collars and ports.

A combination of these conditions can be used to specifically manipulate a microalgal cell culture to produce a product of interest. The product of interest can be a water-soluble carotenoid, for example, a water-soluble carotenoid produced by culturing an algae belonging to the genus Haematococcus or a capsular exopolysaccharide produced by culturing an algae belonging to the genus Parachlorella. Compositions containing the water-soluble carotenoid, for example, as sunscreen and compositions containing the exopolysaccharide, for example, as moisturizing cream are also described.
