Abstract: | Summary Extended Kalman Filter (EKF) is used for the on-line estimation of viable cell and monoclonal antibody (MAb) concentrations during batch and fed batch cultures of the OKT3 hybridoma cell line. A kinetic model and an experimental system are presented. The practicability of EKF is demonstrated under both cultivation modes using glucose and ammonia as observation variables. For the same process duration, the concentration of viable cells and antibodies are twice as high in the fed batch as in the batch culture. |
