Also provided is a method for growing light-sensitive microbes.

A two-stage or two-tier system and method for rapid screening of compounds for inotropic effects is disclosed. The system comprises, in a first tier, an engineered cardiac tissue strip (CTS) comprising cardiomyocytes, such as human ventricular cardiomyocytes, embedded in a biocompatible gel wherein the gel comprises at least two biocompatible structural supports such as polydimethylsiloxane posts for elevating the gel. The system further comprises, in a second tier, an apparatus comprising at least one organoid module comprising at least one organoid cartridge, wherein each organoid cartridge comprises an organoid, and a minor arrangement. The system further comprises at least one detection device, such as a high-speed camera, for detecting deflection of the CTS gel in the first tier of the system and/or for detecting tissue or organoid behavior in the organoid cartridge or cartridges of the second tier of the system. The method comprises application of a compound to the cardiac tissue strip and detection of any deflection of the gel in response to application of the compound to detect compounds showing a possible inotropic effect and introduction of such a compound to an organoid module, wherein modified contractility of the cardiac tissue or organoid in the organoid module identifies a compound having an inotropic effect. A method of making a cardiac tissue strip is also provided. The second tier system is also useful in methods of producing and monitoring, characterizing, manipulating or testing one or more organoids (e.g., human organoids) ex vivo. The system, methods, apparatus, and compositions are useful in a variety of contexts, including the assessment of potential therapeutics for efficacy and/or toxicity.

The present invention relates to a photobioreactor for treatment of the waste water. The photobioreactor comprises a treatment chamber for receiving a culture of algae, a water inlet for supplying waste water to said chamber, at least one light source provided within said chamber for providing light to said culture and at least one water outlet for removal of treated water. The at least one water outlet is further arranged in use to selectively remove a proportion of the biomass produced within said chamber when said biomass reaches a predetermined maximum level so as to maintain a continuous or substantially continuous culture of algae within said chamber.

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.

Disclosed is a mass-cultivation system for microalgae, including a reactor that contains a cultivation liquid in the interior thereof, wherein the liquid includes functional particles. According to the mass-cultivation system for microalgae according to the present invention, because various functions that are necessary for cultivation of microalgae may be uniformly distributed in a cultivation liquid by allowing functional particles having various functions to flow in the cultivation liquid, a suitable environment may be created based on the cultivation of a large amount of microalgae and the growth of microalgae so that a high efficiency cultivation system may be realized while the problems of mass-cultivation of an existing cultivation system may be solved.

A photobioreactor system and a process for its use is illustrated, whereby water and nutrients from multiple sources are balanced (mixed using aeration) to the specific requirements of the particular photosynthetic organism strain used, sterilized, further mixed to balance the system and seeded with the photosynthetic microorganism, e.g. microalgae (dilution of a concentrated stock or added to an existing algal biomass). In accordance with such an embodiment, the algal biomass is then grown for a most efficient number of hours in a totally controlled environment where temperature (using aeration, an internal coil cooling system, or a combination thereof), pH (via CO.sub.2 delivery) and light delivery (using internal lighting directly inside the algal biomass) are optimized to the algal strain grown.
