Systems For Cell Culture Scaling
20230091993 · 2023-03-23 ·

The present set of embodiments relate to a bioproduction system, method, and apparatus for creating a scalable bioreactor system. Specifically, the present set of embodiments enable the determination of bioreaction performance characteristics of a commercial scale by matching operational parameters between a small test scale bioreaction to that of a commercial scale bioreaction. The system and methods do not rely on simply making bioreactor apparatuses across scales the same dimensionally which would not account for differences in fluid dynamic properties between very small to very large volumes, but requires tuning of a variety of systems (mixing assembly, sparger system, and headspace airflow system) in conjunction with one another to achieve predictive outcomes.

SYSTEM AND METHOD FOR ORGANOID CULTURE

The present disclosure provides a system, including methods and apparatus, for culturing, monitoring, and/or analyzing organoids. In an exemplary method of organoid culture, the method may comprise disposing a scaffold in a receptacle having an open side. A sealing member may be bonded to the open side of the receptacle to create a chamber. An organoid may be formed in the chamber using the scaffold. Fluid and/or at least one substance may be introduced into the chamber from an overlying reservoir for contact with the organoid.

SYSTEM AND METHOD FOR OPTIMIZATION OF THE FERMENTATION PROCESS

The invention comprises one or more gas volume fraction measurement devices operatively connected to one or more controllers and one or more deaeration mechanisms which receive control signals from said one or more controllers and perform an act on the system, such as by controlling a level of deaeration chemistry into some portion of the fermentation system. In one embodiment, the deaeration mechanism is an antifoam feed pump which pumps antifoam chemistry into a feed line of the fermenter in response to the measured gas volume fraction in the fermenter's recirculation loop, in an amount determined by the controller to be effective to reduce foaming and lower column height in the fermenter.

METHOD FOR PRODUCTION OF A SOIL AMENDMENT

A system and method for the production of microbial consortiums and by-product material is provided. A physical containment system comprising phase spaces arranged in a discrete order to favor specific biological reactions is also provided. Phase profiles and phase data sets include the pre-determined physical and biological parameters for the phase space transitions. Movement of material from one phase to the next is hydraulically balanced enabling working fluid to continuously move in a fixed direction and rate of flow. Continuous monitoring of phase profiles and phase data sets provide feedback to the system enabling alteration of the conditions in the system to control reactions therein.

SYSTEMS AND METHODS FOR GENERATING BACTERIOPHAGES ADAPTED TO INFECT A TARGET BACTERIAL STRAIN

One aspect of the invention provides a method of generating bacteriophages adapted to infect a target bacterial strain. The method comprises: providing host bacteria that are susceptible to phage as input to a host chemostat containing phage; providing target bacteria that are related to the host bacteria, but not susceptible to phage as input to a target chemostat containing phage; filtering outflows from the host chemostat and the target chemostat to isolate phage from the populations of the host bacteria, the target bacteria, and macromolecules; combining the outflows; and introducing the combined outflow into each of the host chemostat and the target chemostat.

Example embodiments include a cell culture apparatus, methods for cell cultivation by using the cell culture apparatus, and a cell culture incubator comprising the cell culture apparatus. The cell culture apparatus comprises a plurality of cell culture modules arranged adjacent to each other. Each cell culture module comprises two or more culture medium reservoirs connected by two or more flow channels that go through a basal chamber arranged under an apical chamber. The apical and basal chambers are separated by a porous membrane. The basal chamber has a bottom part arranged higher than a bottom part of each of the culture medium reservoirs. The culture model comprises further a cavity under at least the bottom part of the basal chamber and at least one means for capturing at least one image from a bottom and/or top of the at least one cell culture module.

Systems and methods for producing a sugar stream

An improved dry grind system and method for producing a sugar stream from grains or similar carbohydrate sources and/or residues, such as for biofuel production. In particular, a sugar/carbohydrate stream, which includes a desired Dextrose Equivalent (DE) where DE describes the degree of conversion of starch to dextrose (aka glucose) and/or has had removed therefrom an undesirable amount of unfermentable components, can be produced after saccharification and prior to fermentation (or other sugar conversion process), with such sugar stream being available for biofuel production, e.g., alcohol production, or other processes. In addition, the systems and methods also can involve the removal of certain grain components, e.g., corn kernel components, including protein, oil and/or fiber, prior to fermentation or other conversion systems. In other words, sugar stream production and/or grain component separation occurs on the front end of the system and method.
