A CELL CULTURE CHAMBER DEVICE FOR CELL AND TISSUE GROWTH
A cell culture chamber device for growing cell cultures and tissues. The device includes: an enclosure containing a cell culture media, the enclosure being defined partly by a first end, a second end, and a connecting wall. The first end or a part or window thereof is substantially transparent, and the second end and/or the connecting wall, or a respective part or window thereof, is/are substantially transparent/translucent. The first end is configured to be optically aligned, at least for some period of time or periodically, with the second end and/or with the connecting wall so that light or another illumination or visualisation signal, transmitted through or by the second end and/or through or by the connecting wall into the enclosure is transmitted through the cell culture media and out through the first end to outside the enclosure, and e.g. to outside the cell culture chamber device.
Growth of bacterial host cells in gas permeable low-density polyethylene bags for production of plasmid DNA or recombinant molecules
The present disclosure pertains to methods of growing bacterial host cells in a low-density polyethylene (LDPE) bag to produce plasmid DNA or express recombinant protein. The LDPE bag is filled with media, an antibiotic, and host bacterial cells that have been transformed with plasmid DNA encoding a protein of interest. The LDPE bag is sealable to the external environment and incubated at a growth temperature until a desired concentration of bacteria is achieved. When plasmid DNA is desired, host cells are harvested and plasmid DNA is separated from host cell components. When recombinant protein is desired, expression is induced while host cells are in the LDPE bag, followed by the harvest and separation of the recombinant protein. The LDPE bags are sterile and conducive to bacterial growth equal to or greater than that afforded by conventional shake flasks under similar growth conditions.
EXTRACTION APPARATUS AND EXTRACTION METHOD FOR A FERMENTATION MEDIUM
An extraction apparatus for a fermentation medium comprises an extraction chamber configured to receive a fermentation medium and comprising a lower portion and an upper portion above the lower portion, as well as a feed device configured to feed at least one gas and one liquid into the lower portion of the extraction chamber, as well as a discharge opening arranged in the upper portion of the extraction chamber and configured to drain a washout liquid, loaded with microorganisms, from the extraction chamber.
CELL CULTURE DEVICE
A cell culture device (200) includes a cell culture vessel (22) for culturing cells, a factor container (81) for storing a factor, a reagent container (82) for storing a reagent for introducing the factor into the cells, and a flow path for transporting the factor and the reagent from the factor container (81) and the reagent container (82) to the cell culture vessel (22).
ROTARY INTERFACE FOR FLUID ASSEMBLIES AND RELATED METHODS OF FABRICATION AND USE
The present disclosure provides advantageous rotary interfaces for fluid assemblies (e.g., rotary interfaces for fluid flow in bioreactor applications), and related methods of fabrication and use. More particularly, the present disclosure provides improved rotary interfaces for fluid flow through porous impellers for filtration and/or sparging for fluid assemblies (e.g., bioreactor applications), and related methods of fabrication and use. Disclosed herein is a fluid assembly (e.g., bioreactor) that includes a porous impeller which is in fluid communication with a hollow shaft that can be used to transport a reaction fluid to an external storage tank or the like. The fluid assembly/bioreactor can include a coupling mechanism that transmits rotary motion from a motor to a primary shaft and then to a hollow secondary shaft, while at the same time permitting removal of a filtrate from the fluid assembly or bioreactor via the hollow secondary shaft and a porous impeller.
CELL CULTURE DEVICE
A cell culture device is provided. A cell culture device according to an exemplary embodiment of the present invention comprises: a housing which has a plurality of through-holes formed through at least one surface thereof to allow carbon dioxide to be introduced thereinto from the outside and includes an inner space filled with a medium for culturing cells; a plurality of supporters which are arranged in the inner space in multiple steps while being spaced at an interval from each other so as to culture cells and are provided in a plate-shape having a predetermined area; and a porous member which is attached to one surface of the housing so as to cover the plurality of through-holes, prevents the medium filled in the inner space from leaking to the outside, and allows carbon dioxide to be introduced into the inner space from the outside.
Solid state fermentation reactor equipped with active support material
An active solid state fermentation bioreactor for producing gases, liquid(s) or solids from gaseous or gaseous and liquid starting materials and a fermentation process using the reactor are disclosed, The bioreactor includes three major phases; a solid phase including the porous solid support, a liquid phase comprising liquid, and a gaseous phase. The solid phase includes a porous solid support, in which at least 20% of the pore volumes have a size resulting in a liquid suction of about 0.01 to about 0.1 bars if these pores are filled with liquid, the porous solid support is inoculated with desired micro-organisms, the volume of the gaseous phase is 20% to 60% of the volume of the bioreactor, and the liquid phase is at least 20% of the reactor volume, The unsaturated capillary conductivity of filling/packing solid material of the bioreactor is at least 0.1 cm/ h. The solid state fermentation bioreactor enables a large gas-liquid interface, in which the filling material has a good capillary conductivity despite the unsaturated state.
