(692f) Model Predictive Control: A Process Development Tool for Mammalian Cell Culture Processes
AIChE Annual Meeting
Thursday, November 17, 2016 - 2:00pm to 2:18pm
A model predictive control (MPC) technology platform incorporating Raman spectroscopy was developed as a tool to streamline upstream bioprocess development and applied to a fed-batch CHO culture. In this talk, the core elements of the MPC will be discussed, namely the development of the Raman PAT method for the online quantification of cell density, substrate and metabolite concentrations, the process model and the MPC control algorithm.
The application of the MPC to process development will be demonstrated through a case study of its application to a CHO fed-batch culture. The MPC enabled the transition from traditional bolus to a PAT-enabled continuous feeding strategy in order to prevent nutrient depletion and deliver a stable macro-environment for the cells. Overall, application of the glucose set-point control strategy resulted in a 1.5 fold increase in peak viable cell density (VCD) and the integral of the viable cell density (IVC) which is directly related to increased titre.
