摘要： A system and method for controlling a mammalian cell culture process are provided. Such control of the cell culture process involves control of the level of dissolved carbon dioxide in the cell culture media and the resulting ability to prevent increases in the osmolality level is achieved by enhanced stripping of carbon dioxide with little or no damage to the mammalian cells. The disclosed methods and systems of dissolved carbon dioxide stripping include enhanced surface gas exchange mechanisms within the bioreactor vessel through the use of an upward flow impeller combined with vertical baffles to convert swirling motions of the liquid into a largely vertical flow.

摘要： Methods for controlling the level of dissolved carbon dioxide and limiting osmolality in a mammalian cell culture process to enhance cell growth, viability and density, and increase biologic product concentration and yield are provided. Such control of the level of dissolved carbon dioxide and pH as well as the resulting ability to limit osmolality in a mammalian cell culture process is achieved by adopting alternative pH control strategies and CO2 stripping techniques during a mammalian cell culture process. Such pH control techniques and carbon dioxide stripping occur without foam and with little or no damage to the mammalian cells.
