Bioreactor and uses thereof
The present invention relates to the field of fermentation. In particular, the present invention relates to a method and apparatus for production of products by use of living cells or active components derived from such cells using a bioreactor having a built in gas distributor and a specific system/device for handling foam formed in the process. The invention also relates to a bioreactor comprising: a reaction chamber having a fermentation zone and a foam settling zone, wherein the reaction chamber is arranged such that the foam settling zone is spaced from or physically separated from the fermentation zone so as to reduce the effect of activity in the fermentation zone on foam in the settling zone. The separation of the fermentation zone from the activity of the fermentation zone encourages settling of the foam. The invention also provides a method of forming a bioreactor comprising: overlapping two flat, flexible sheets of material; and causing said two sheets to adhere to each other in selected areas so as to define a reaction chamber. This is a particularly cost-effective way to produce a single use, disposable reactor.
Method for producing a product (e.g. polypeptide) in a continuous cell culture fermentation process
A method for improving productivity in microbial fermentations and mammalian cell culture bioreactors.
Ejector Equipped Fermenter
Disclosed is a fermenter comprising one or more two phase injectors for providing oxygen for the fermentation and a circulation loop, circulating the fermentation broth and providing liquid for the two-phase injectors. Further disclosed is a fermentation plant comprising one or more fermenters of the invention and utility for the fermenters. Also disclosed is the use of the fermenters for the production of a fermentation product such as an enzyme.
METHODS AND SYSTEMS FOR PROPAGATING MICROORGANISMS FOR MITIGATING MYCOTOXIN CONTAMINATION, AND RELATED SYSTEMS AND METHODS
Systems and methods for propagating at least one microorganism expressing one or more enzymes to mitigate mycotoxin contamination at a bioprocessing facility.
System, apparatus and method for biomolecules production
An automated method for the production of cells and/or biomolecules such as protein or peptides includes culturing cells in at least one high cell density bioreactor, thereby fluidly connecting said bioreactor with a culture medium supply and a gas or gaseous mixture; fluidly connecting said bioreactor with a downstream unit; and growing cells to a density at least 50 million cells per ml. The total volume of the bioreactor is at least 10 liters. A system suitable for implementation of the automated method above is a small-scale and cupboard-sized system, which can be placed in a portable clean room.
Perfusion bioreactor and related methods of use
A method of controlling a bioreactor system includes providing a cell culture in a bioreactor, wherein conditions in the bioreactor enable the cell culture to produce a protein of interest (POI), measuring process parameters (PPs) of the culture within the bioreactor by RAMAN, wherein the process parameters are selected from the group consisting of nutrient concentration, viable cell concentration, and protein attributes, measuring a predetermined weight of the bioreactor with the cell culture, removing cell-free spent media from the cell culture using a first output conduit at a first specified rate, removing cells from the cell culture using a second output conduit at a second specified rate, and introducing one or both of fresh media or nutrients into the cell culture using an input conduit at a third specified rate.
Multivariate Spectral Analysis and Monitoring for Biomanufacturing
The disclosure features methods that include obtaining a vibrational spectrum of a solution in a biological manufacturing system, analyzing the vibrational spectrum using a first chemometrics model to determine a value of a first quality attribute associated with the solution, analyzing the vibrational spectrum using a second chemometrics model to determine a value of a second quality attribute associated with the solution, and adjusting at least one parameter of a purification unit of the biological manufacturing system based on at least one of the values of the first and second quality attributes.
