Notes:
Oxygen transfer in a novel pulse bioreactor has been evaluated. The agitator consists of a series of alternately fixed and movable parallel plates mounted so that the movable plates vibrate at 30 Hz causing a pulsating fluid motion. Pure oxygen, at pressures up to 5 atm, diffuses through silicone rubber tubing that also vibrates at 30 or 60 Hz. The main feature of this bioreactor is high oxygen transfer with low shear to prevent damage to fragile animal cell membranes. We estimate that sufficient oxygen can be supplied to support over 108 cells/mL of human diploid foreskin cells growing on microcarriers. © 1993 John Wiley & Sons, Inc.
