A culturing device is provided with an accommodation portion that accommodates culturing solution and microalgae. The accommodation portion is inclined with respect to the vertical direction and is supported by a support body. In this state, microalgae are cultured. A gas gathering portion is provided at an upper part of a side wall of the inclined accommodation portion, the outer surface of the side wall facing obliquely upward. The gas produced by the microalgae is gathered by the gas gathering portion.

The invention relates to methods and apparatuses for producing Class A biosolids. In yet another embodiment, the invention relates to a method comprising digesting waste material by anaerobic digestion, and yielding Class A biosolids. In still yet another embodiment, the invention relates to a system for anaerobic digestion of waste material to produce Class A biosolids. In still yet another embodiment, the invention relates to a system for anaerobic digestion of waste material comprising a mixing chamber, a digester, a heating pit, and an effluent pit.

The method of growing a biopolymer material employs incubation of a growth media comprised of nutritive substrate and a fungus in containers that are placed in a closed incubation chamber with air flows passed over each container while the chamber is maintained with a predetermined environment of humidity, temperature, carbon dioxide and oxygen. The air flows may be directed parallel or perpendicularly to the surfaces of the growth media.

A perfusion bioreactor and a perfusion device. Each perfusion device has a mesh structure, and an encapsulated organ tissue (EOT) disposed in the mesh structure. The EOT has a body with a thickness defined between a first surface of the body and a second surface of the body. The body has at least one channel extending into the body from one of the first and second surfaces to receive a fluid therein. The at least one channel has a diameter selected to diffuse solutes out of the fluid and into the body. The perfusion devices are arranged one adjacent to another and spaced apart from each other along the length of the bioreactor to receive fluid, and to perfuse the fluid to the EOT of each perfusion device and to the at least one channel therein. A method of processing blood plasma and an artificial liver system are also disclosed.

A cell culturing system includes a reactor, a flow channel that allows a culture medium to flow into and out of the reactor, a waste liquid channel that discharges the culture medium from the flow channel, and a waste liquid container capable of storing the culture medium passing through the waste liquid channel. The waste liquid channel includes a temporary storage unit capable of temporarily storing the culture medium. The waste liquid container is located below the temporary storage unit) in a gravity direction, and the temporary storage unit is provided above the flow channel in the gravity direction. The temporary storage unit temporarily stores the culture medium discharged from the flow channel and allows the culture medium to flow out toward the waste liquid container.

An incubator for cell and tissue culture under controlled atmospheric conditions has a primary air flow control device that forms a primary, preferably laminar flow, air veil across an opening that allows access to the cells or tissue cultures disposed within the incubator. Preferably, most if not all of the air in the primary (laminar flow) air veil is recirculated, and a secondary air flow control device is used that forms a secondary, preferably laminar flow, air veil between the primary (laminar flow) air veil and a user of the incubator.

A method for biogas production includes feeding a receiving structure with a feed containing biomass that comprises lignocellulose and directing the feed from the receiving structure into an anaerobic secretome bioreactor (ASB) reactor environment which includes a synthetic microbial community consisting of at least one selected from extremophile thermophilic anaerobic microorganisms that are essentially acidogens and acetogens, the synthetic microbial community producing a secretome of exozymes. The ASB treated biomass is further directed to an aerobic digestion (AD) reactor environment, the ASB treated biomass being pasteurized so as to be essentially free of non-thermophilic microorganisms, the ASB treated biomass comprising liquid effluent containing solubilized biomass products and metabolized biomass products, and solid effluent. Contents or heat are recycled through a conduit between the ASB reactor environment and the AD reactor environment.

A system for growing algae includes a gas concentrator configured to receive a first gas containing CO2 at a first concentration and discharge a second gas containing CO2 at a second concentration higher than the first concentration, and a photobioreactor containing algae in an algae slurry and fluidically coupled to the gas concentrator to receive the second gas. A recycling line extends from a gas outlet on the photobioreactor to remove a third gas from the photobioreactor for future use in the photobioreactor.
