An anaerobic digestion device based on self-sustained air flotation includes an anaerobic digestion tank unit, a self-sustained air flotation screening unit and a biogas measurement and collection unit. The self-sustained air flotation screening unit includes an air flotation screening part, a material sedimentation part, a reflux part and a three-phase separation part connected sequentially from bottom to top. A digested material in the anaerobic digestion tank unit is pumped into the air flotation screening part, overflows into the material sedimentation part, and then is raised to the reflux part. Gas passing through the three-phase separation part and gas produced in the anaerobic digestion tank unit enter the biogas measurement and collection unit to be measured and collected.

A heating assembly for a bioreactor is disclosed. The heating assembly includes a holder having a plurality of segments coupled to each other to define a unitary structure and a heating component coupled to at least one segment of the plurality of segments. The unitary structure includes a top end, a bottom end, and a side wall. The side wall extends between the top end and the bottom end and along a circumferential direction of the heating assembly to define a cavity. At least a portion of the unitary structure has a gradually varied perimeter along a direction perpendicular to a plane which intersects the side wall and is parallel to the top end and the bottom end.

Reactor for enzymatic hydrolysis of a raw material comprising in sequence: i)—a first heat exchanger adapted to heat the raw material supplied to the reactor to a temperature within a range that favours enzymatic hydrolysis, ii)—a reactor comprising plural in reactor chambers connected in series, separated by closable valves, iii)—a second heat exchanger adapted to heat the reaction mixture to a temperature higher than the temperature range favouring enzymatic hydrolysis, the reactor being formed with inclined tubular reactor chambers assembled to form a reactor with vertical axis, the first reactor chamber being the vertically uppermost chamber of the reactor, while at least one reactor chamber is adapted to be stirred with a through-flowing inert gas.

Systems and methods are provided for growing algae and/or other microorganisms in a controlled environment while reducing or minimizing the amount of energy required for maintaining desired conditions in the growth medium. The systems can be based on a photobioreactor having a “tube-in-tube structure”, where an outer cylindrical tube contains a heat regulation fluid that surrounds one or more inner cylinders that contain microorganisms in growth media. The heat regulation fluid in the outer cylinder, as well as the outer cylinder itself, can assist with regulating the temperature of the growth media in the inner cylinder(s).

A dynamic incubator system and method for mammalian cells. The dynamic incubator system includes an incubator and a programming device communicatively coupled to the incubator. The programming device includes a memory, one or more processors, a display, and an input mechanism. The programming device is adapted to enable at least one preset temperature and gas concentration sequence to be one or more of designed for the interior of the incubator, saved to the memory of the programming device and/or selected for implementation within the interior of the incubator. The at least one temperature and gas concentration sequence includes programmed changes to the temperature and a CO.sub.2 gas concentration. A purging mechanism is coupled to the incubator and releases a portion of a gas concentration to enable rapid changes in the temperature and gas concentration in the incubator.

An enzymatic processing plant for continuous flow-based enzymatic processing of organic molecules, comprises an enzymatic processing area, wherein the enzymatic processing area comprises a turbulence-generating pipe with a repeatedly changing centre-line and/or a repeatedly changing cross-section, for generating turbulence to mix a reaction mixture and prevent sedimentation of particles as the reaction mixture is flowing through the turbulence-generating pipe, and wherein the enzymatic processing plant and the enzymatic processing area are arranged such that the reaction mixture is subjected to turbulence within the enzymatic processing area for a reaction time of 15 minutes or more.

An inclined reactor of bottom gas-inlet type for aerobic fermentation and a method for aerobic fermentation are provided, a fermenter is provided with a circular inner tank, end covers and a jacket; an airtight fermentation space is formed in the fermenter by the inner tank, an upper end cover and a lower end cover; a feed opening and an exhaust outlet are arranged at an upper part of the fermenter, and a discharge opening is arranged at a lower part of the lower end cover of the fermenter; a length of the fermenter is greater than or equal to a diameter of the fermenter, the fermenter is fixed on a base having a height difference and is hence in an inclined state; an energy-saving stirrer is mounted in the fermenter, and the energy-saving stirrer is formed by connecting several groups of tangential plates or a spiral combination of tangential plates, a radial rod, a stirring rod and a stirring shaft; several groups of air chambers are arranged at an external wall at the bottom of the inner tank of the fermenter, the air chambers are arranged inside the jacket, several aeration nozzles are defined on an inner side of each air chamber, and the aeration nozzles are close to the inner tank.

A system and method for producing bio-organic compounds may include a vessel, a first phase comprising an aqueous medium including host cells capable of producing a bio-organic compound, where the bio-organic compound comprises a second phase in contact with the aqueous medium.

A configurable system for repeatably performing processes related to tissue growth in a controlled environment, possibly part of an industrial production line. The system can accommodate various sizes and shapes of culture vessels, and can maintain the cells at a desired temperature in the culture vessels, thus enabling a plug and play system that can produce consistent and repeatable results. The system includes gas management, fluid management, and control of multiple processes simultaneously, and can be automatically operably coupled with a variety of supporting technologies that can enable tissue-related processes. The system can communicate with supporting technologies upstream and downstream on a manufacturing line, enabling fully automated process control, centralized data historization, and centralized control.

A method for directly bonding a metal to a transparent substrate includes providing a substrate; placing a metal foil directly on a face of the substrate; irradiating a portion of the metal foil with a laser beam so that metal corresponding to the portion melts and bonds directly to the substrate and forms a metal pad; and pumping a gas above the portion to prevent oxidation of the melted metal.
