Membrane bioreactor for simultaneous enzymatic cellulose hydrolysis and product separation

The membrane bioreactor for simultaneous enzymatic cellulose hydrolysis and product separation is a vessel having a lower hydrolysis reaction chamber and an upper distilled water chamber separated by a semipermeable membrane attached to the top of the lower reaction chamber. The membrane is supported on a stainless steel mesh and sealed to the mesh by epoxy glue to prevent leakage. A peristaltic pump is connected to the reaction chamber and maintains a flow of distilled water through the membrane and the upper chamber, the effluent being collected in a beaker or other product collection vessel. The reaction chamber is agitated at a moderate rate by a magnetic stirrer, and the upper chamber is agitated more rigorously by a mechanical stirrer. A thermocouple and temperature controller and a buffer solution, respectively, maintain temperature and pH in the reaction chamber optimal for enzymatic hydrolysis of cellulose.

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.

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.
