ABSTRACT:
Methods and apparatus are provided for growing both suspension type cells and anchorage dependent cells in airlift bioreactors. A packing means, such as stainless steel wool, is provided in the growth chamber of the bioreactor to increase cell density by trapping suspension cells or acting as a solid support for anchorage depended cells without interfering with gentle circulation of liquid growth medium in the bioreactor.
