  • Process for improving mass transfer in a membrane bioreactor and providing a more homogeneous culture environment
    Patent number: 5202254
    Abstract: A process for improving mass transfer in a bioreactor having at least one semi-permeable membrane defining first and second chambers on opposite sides of the membrane provides for circulating a first media including nutrients and the like through the first chamber and for circulating a second media for cell culture through the second chamber of the bioreactor. The first and second media may be circulated through a plurality of bioreactors connected in parallel while balancing the flow in each reactor. The flow in the second circuit can be periodically reversed to provide increased cell culture.
