Using MVDA with stoichiometric balances to optimize amino acid concentrations in chemically defined CHO cell culture medium for improved culture performance

Taha Salim et al.

Summary: In this study, the utilization of multivariate data analytics (MVDA) coupled with amino acid stoichiometric balances (SBs) was demonstrated to increase cell growth and monoclonal antibody (mAb) productivity in efforts to support CD media development. Stoichiometric balances measure the difference between theoretical demand of amino acids and empirically measured fluxes to identify various catabolic or anabolic states of the cell, resulting in a 55% increase in total cell growth and about an 80% increase in total mAb productivity through optimized CD media.

Predicting the hydrodynamic properties of a bioreactor: Conditional density estimation as a surrogate model for CFD simulations

Umut Kaya et al.

Summary: The rising demands in biopharmaceutical manufacturing call for a deep understanding of the underlying bioprocesses, which can be achieved through computational fluid dynamics (CFD) simulations. This approach allows for the prediction of hydrodynamics properties and process design. However, CFD simulations are computationally demanding and limited to a small set of input parameters. To address this limitation, the proposed approach offers a computationally tractable model that can interpolate the volume-averaged distributions of hydrodynamic properties, providing a balance between the expressiveness of a CFD simulation and a basic regression model.
