ABSTRACT:
The present invention uses one or more bags that are capable of being selectively pressurized and deflated in conjunction with a disposable bio bag such as a fermenter, mixing bag, storage bag and the like. The pressure bag(s) may surround a selected outer portion of the bag or may be contained within an inner portion of such a bag. By selectively pressurizing and deflating the pressure bag(s), one is able to achieve fluid motion in the bag thereby ensuring cell suspension, mixing and gas transfer within the bag without damaging shear forces or foam generation.
