Systems and methods relating to dynamic spargers for generating fine bubbles within reactors such as biological and chemical reactors. A sparger system is positioned within a reactor and comprises a support plate, multiple annular shrouds engaged with the support plate, and spargers positioned within the annular shrouds defining a gap between an interior surface of the annular shroud and an exterior surface of the corresponding sparger. Liquid flows through the defined gap between an interior surface of the annular shroud and an exterior surface of the sparger. Acceleration of the liquid through the gap shears bubbles at the exterior surface of the sparger creating bubbles or fine bubbles.

Computerized devices provide microscopy and electrochemistry tests, performed in dual channels. The devices can be brought to the field, for on-site testing with instant results. The dual channels include an imaging (optical or microscopic) channel and a signal channel Microfluidic chips are disclosed for use with the microscopy channel optics.

Disclosed herein is a microalgae incubator. The microalgae incubator is formed as a container in the form of a barrel having an open upper surface and a predetermined depth to accommodate water containing microalgae. The microalgae incubator has a regular polygonal cross section having an even number of vertices or a circular cross section. The microalgae incubator includes an air pipe configured such that an inner tube is located inside the microalgae incubator along a direction passing through a center of a cross section in a lower portion of a body of the microalgae incubator and both ends of the inner tube form connection holes in a surface of the body of the microalgae incubator.

Provided is a cell culture device that has a simple structure and ensures sufficient nutrient supply to cells and oxygenation of the cells to thereby enable mass cell culture. The cell culture device comprises: a cell culture container which is an approximately cylindrical body provided with a flat bottom part at the lower end; a dish-shaped body having an approximately disc shape which is provided with a plurality of magnetic attraction members, said magnetic attraction members being positioned in the circumferential part at equal intervals, and horizontally disposed in a non-contact state within a hollow space inside the cell culture container; and a cyclic body which is provided with a plurality of magnetic attraction members and positioned outside the cell culture container so that the cell culture container is located within the cycle thereof. The cyclic body and the dish-shaped body move vertically in magnetic conjunction to thereby agitate a medium and supply nutrients to cells.

The invention relates to a digester for a liquid medium, comprising a container, a dividing wall between two spaces, and a device for injecting gas into the lower part of one of the spaces. The gas creates an upflow of the mixture of liquid medium and injected gas in said space, and a downflow in the other space. The dividing wall is equipped with at least one device for establishing a fluid communication between the spaces, so that the fluid communication configuration is automatically varied between a first open configuration in which fluid can flow freely from one space to the other, and a second closed configuration in which the flow of fluid is blocked fully or partially by the aforementioned device.

A computerized device provides microscopy and electrochemistry tests, performed in dual channels. The device can be brought to the field, for on-site testing with instant results. The dual channels include an imaging channel and a signal channel.

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.

A bioreaction container including a culture chamber configured to contain a culture solution and a life form in an inner space, the culture chamber having an open upper end; a chamber cover portion coupled to the upper end of the culture chamber, the chamber cover portion having a protruding tube provided on one side thereof so as to communicate with the inner space; a filter cap coupled to the protruding tube in an attachable/detachable manner so as to open/close the protruding tube; a gas introduction portion configured to penetrate the chamber cover portion and to communicate with the inner space so as to supply a predetermined gas into the inner space; and an acidity/basicity adjustment portion installed on the chamber cover portion while containing an adjustment solution that adjusts pH of the culture solution such that the adjustment solution is discharged into the inner space by pneumatic pressure.

The invention relates to a microbioreactor module for the three-dimensional cultivation of cells, especially stem cells. Said microbioreactor is intended for single use and, in an embodiment of the invention, can be used as a multi-microbioreactor.
