Abstract
A continuous fermenter vessel such as an air-lift fermenter for receiving and cultivating a suspension culture of cells. The vessel contains a mechanism for agitating the suspension culture received in the vessel and causing a gross flow movement of the suspension culture. The vessel includes an inlet for continuously supplying culture medium to the vessel and an outlet for removing the culture supernatant. A filter material is disposed inside the vessel so that the gross flow movement of the suspension culture substantially prevents clogging of the filter material by cells and/or cell debris.
