Nadine Kuhl (process chemist) and Jacob Forstater (engineer and physicist) join the pod to share a pretty neat story that had its origins from a chemical catalog brochure advertising a new and green solvent called Cyrene. From that brochure blossomed a really amazing biocatalytic transamination to make a key chiral amine building block. In order to make this process more robust and tolerant of organic solvents, the team immobilized the transaminase enzyme and leveraged a Spinchem rotating bed reactor (we also had no idea what this was, but now we do) to make a robust process. We learned a lot on this episode, and we hope you do too!
