Using high cell density cultures is an efficient way to increase the volumetric productivity of fermentation processes, thereby enabling faster and more robust processes and use of smaller reactors.
WebHigh cell density fermentation (HCDF) is widely used to provide a high level of productivity to derive proteins or cells. For these cultures the oxygenation capacity of conventional bioreactors like stirred tanks or bubble columns is rapidly exhausted. The dissolved oxygen concentration usually becomes limiting for microbial growth.
