  • Method for culturing mammalian cells in a horizontally rotated bioreactor
    Patent number: 5153133
    Abstract: A bio-reactor system where cell growth microcarrier beads are suspended in a zero head space fluid medium by rotation about a horizontal axis and where the fluid is continuously oxygenated from a tubular membrane which rotates on a shaft together with rotation of the culture vessel. The oxygen is continuously throughput through the membrane and disbursed into the fluid medium along the length of the membrane.
    Type: Grant
    Filed: April 15, 1991
    Date of Patent: October 6, 1992
    Assignee: The United States of America as represented by the Administrator, National Aeronautics and Space Administration
    Inventors: Ray P. Schwarz, David A. Wolf, Tinh T. Trinh
