CELL CULTURE BIOREACTOR WITH ZONE CONTROL

A cell culture bioreactor has membranes divided into a plurality of zones. The membranes may include perfusion membranes carrying a liquid media and/or gas transfer membranes. The bioreactor has one or more sensors configured to collect data from one or more locations within the bioreactor. The supply of one or more of the gaseous and/or liquid media to a selected zone or zones may be controlled. In some examples, the supply includes a background supply and a selectable incremental supply. The bioreactor may be used to grow cells in suspension. Liquid media circulates within an extra-capillary space of the bioreactor. In some examples, a portion of cells is permitted for a period of time to be restrained within one or more zones of the membranes. Elements of a reactor may be made in a mold. A reactor may be operated in a fed-batch process.

CELL CULTURE DEVICE

A cell culture device for culturing cells in a closed container kept in an aseptic state includes: a chamber including an opening/closing part capable of being opened and closed; a connection path configured to connect closed containers accommodated in the chamber to each other and each having an inside kept in an aseptic state; a driving part configured to move cells from one closed container to the other closed container via the connection path; and a container attachment/detachment device. After the cells are moved from one closed container to the other closed container, the container attachment/detachment device is configured to remove one closed container from the connection path while maintaining an aseptic state inside the other closed container and the connection path, and connect a new closed container loaded into the chamber to the connection path while maintaining an aseptic state inside the new closed container.

Single Use Bioreactor

A single-use bioreactor is provided. The single-use bioreactor may include a bioprocess container, a shell, at least one agitator, at least one sparger, at least one gas filter inlet port for the sparger(s) and headspace overlay, at least one fill port, at least one harvest port, at least one sample port, and at least one probe. In examples, at least one controller may monitor and control one or more parameters associated with the single-use bioreactor A method to cultivate and propagate mammalian cells is also provided. The method may include cultivating under suitable conditions and in a suitable culture medium in a first single-use bioreactor, transferring the medium containing the cells obtained by propagation from the at least one mammalian cell is into a second single-use bioreactor, transferring the medium containing the cells obtained by propagation from the at least one mammalian cell is into a third single-use bioreactor, and cultivating the cells in the third bioreactor.

Heat exchanger system with flexible bag

A bag assembly for use with a heat exchanger includes a flexible bag having of one or more sheets of polymeric material, the bag having a first end that bounds a first compartment and an opposing second end that bounds a second compartment, a support structure being disposed between the first compartment and the second compartment so that the first compartment is separated and isolated from the second compartment. A first inlet port, a first outlet port, and a first drain port are coupled with the flexible bag so as to communicate with the first compartment. A second inlet port, a second outlet port, and a second drain port are coupled with the flexible bag so as to communicate with the second compartment.

BIOREACTOR WITH ADDITION TUBE
20230093940 · 2023-03-30 ·

The invention discloses a bioreactor with a vessel defining an inner volume, agitation means and at least one addition tube, wherein a delivery orifice in the addition tube is located within the inner volume and a check valve is arranged in proximity of the delivery orifice for allowing flow of a fluid in the direction from the addition tube into the inner volume of the vessel and blocking flow in the reverse direction.

Integrated waste conversion system and method

An entirely water-based, energy self-sufficient, integrated in-line waste management system is provided for comprehensive conversion of all organic fractions of municipal and wider community waste to fuels suitable for use in transportation, with all solid residues converted to high nutrition compost. The system is based on a combination of pre-treatment, involving alkaline hydrolysis and saponification; three-way separation of the pre-treated waste into different streams that are each directed to suitable further processing including fuel production; which includes biodiesel generation in a continuous-flow catalytic esterification unit, and anaerobic digestion to produce methane or other small molecule biofuel. Remaining solids are converted to compost in a quasi-continuous process.

PLATFORMS AND SYSTEMS FOR AUTOMATED CELL CULTURE

Disclosed herein are platforms, systems, and methods including a cell culture system that includes a cell culture container comprising a cell culture, the cell culture receiving input cells, a cell imaging subsystem configured to acquire images of the cell culture, a computing subsystem configured to perform a cell culture process on the cell culture according to the images acquired by the cell imaging subsystem, and a cell editing subsystem configured to edit the cell culture to produce output cell products according to the cell culture process.

Integrated Bioreactor Apparatus for Fabricating Polyhydroxyalkanoate Bioplastic Products
20230101520 · 2023-03-30 ·

The present disclosure provides an integrated and energy-efficient apparatus for the fabrication of completely biodegradable Polyhydroxyalkanoate, PHA, bioplastic products. The apparatus combines a bioreactor fermenter, mixing chambers, and an oven and mold chamber in a single compact design, allowing the entire fabrication process to be handled by a process controller if desired. Plates, cups, masks, packaging materials, and other plastic products can be produced directly from biomass media, with solvents and other agents recycled within the apparatus between batches.

CELL CULTURE ANALYZER AND CELL CULTURE ANALYSIS METHOD USING SAME, ADDITIVE SUPPLY UNIT AND CELL CULTURE ANALYZER PROVIDED THEREWITH, AND SENSOR UNIT AND CELL CULTURE ANALYZER PROVIDED THEREWITH

A cell culture analyzer comprises a stirring member and an air discharge and intake unit. The stirring member is used in a state of being immersed in a medium, and has a liquid discharge and intake port for discharging or drawing in the medium, and an air discharge and intake port for discharging or drawing in air in order to discharge or draw in the medium from the liquid discharge and intake port. The air discharge and intake unit is linked to the air discharge and intake port of the stirring member, and discharges or draws in the air discharged or drawn in from the air discharge and intake port.

Methods for Mixing a Fluid with Foldable Impellers

A method of mixing a fluid includes at least partially unfolding a collapsible bag bounding a compartment, the collapsible bag containing in the compartment at least a portion of an elongated drive line or drive shaft and an impeller secured to the drive line or drive shaft, the impeller including a plurality of impeller blades that are pivotable relative to the drive line or drive shaft, at least one of the plurality of impeller blades being in a collapsed position. A fluid is delivered into the compartment of the collapsible bag.
