CELL CULTURE APPARATUS AND CELL CULTURE METHOD
Provided is a cell culture apparatus including a culture vessel that stores a cell suspension containing cells; a first filter part that has a first filter membrane that performs membrane separation treatment on the cell suspension extracted from the culture vessel; a first circulation flow path that allows components blocked by the first filter membrane to return to the culture vessel; a second filter part that has a second filter membrane that performs membrane separation treatment on components of the cell suspension permeated through the first filter membrane; a second circulation flow path that allows components permeated through the second filter membrane to return to the culture vessel; and a recovery flow path that recovers components blocked by the second filter membrane. In the cell culture apparatus, an average hole diameter of the first filter membrane is 20 .Math.m or smaller, and 0 < B/A ≤ 0.5 is satisfied in a case where an average hole diameter of the first filter membrane is A and an average hole diameter of the second filter membrane is B; or an average hole diameter of the first filter membrane is 20 .Math.m or smaller, and the second filter membrane is an ultrafiltration membrane.
FLUID FILTRATION SYSTEM
An improved fluid filtration system is described. The system uses improved sensor assemblies to avoid the problem of biomass build up and reduce the holdup volume of liquid outside of the process vessel. It significantly enhances the performance, robustness and consistency of the filtration.
BIOREACTORS CONFIGURED FOR UV STERILIZATION, AND METHODS OF USING UV STERILIZATION IN BIOPROCESSES
In some variations, a UV-sterilizable bioreactor system comprises: a chamber configured to carry out a reaction; a component configured for introducing a gas into the chamber; and one or more UV light sources configured to expose ultraviolet light to surfaces within the chamber. Some variations provide a method of cleaning and sterilizing a bioreactor, comprising: providing a bioreactor system with a chamber to carry out a reaction, a component for introducing a gas into the chamber, and one or more UV light sources to expose ultraviolet light to chamber surfaces; cleaning the chamber; and exposing the chamber to UV radiation to sterilize the chamber. The disclosed technology is a fundamental advance in the field of sparged bioreactors, for many types of commercial fermentations. The bioreactor may incorporate materials that are expressly incompatible with steam sterilization, which allows for the use of lower-cost materials, among many other benefits from UV sterilization.
CULTURE DEVICE
A culture device includes a culture vessel that contains a culture solution for culturing cells, a gas supply device that supplies a gas to the culture vessel, and a humidification device that humidifies the gas flowing from the gas supply device to the culture vessel. The humidification device includes a hollow fiber membrane filter that includes a hollow fiber membrane through which the gas from the gas supply device passes and a casing that accommodates the hollow fiber membrane, a water supply device that fills the casing of the hollow fiber membrane filter with water, and a first heater that heats the hollow fiber membrane filter.
