Integration of Bayesian optimization and solution thermodynamics to optimize media design for mammalian biomanufacturing

Le résumé fourni par la source

Rapid, cost-effective biomanufacturing of products like therapeutics, materials, and lab-grown foods depends on optimizing cell culture media, a complex and expensive task due to the combination of components and processing variables. This is especially important for therapeutic production using mammalian systems like Chinese Hamster Ovary (CHO) cells, where long development timelines contribute to high drug costs. Using Bayesian optimization (BO), adapted for bioprocess applications, our method supports multiple parallel experiments and incorporates thermodynamics-based constraints on media solubility to ensure feasible medium formulations. The approach is validated both in-silico and in experimental bioreactor settings, showing improved product titers compared to classical design of experiments (DOE) methods. This work bridges machine learning and physical modeling to create a more data-efficient process optimization strategy. The integration of this method into biomanufacturing pipelines together with robotics-assisted bioreactors paves the way for automated bioprocess optimization and more rapidly available and affordable biotherapeutics.
