When aiming to perform such reactions in continuous flow, possibly coupled with product separation, membrane technologies can be of particular interest . Membrane contactors are known to offer operational flexibility, large and tunable interfacial area, modular linear scaleup which allows easy concatenation with other operations, compactness, and low energy consumption. Therefore, researchers have implemented membrane contactors at the outlet of the transamination flow reactor to separate their outputs . In these processes, membranes are solely employed as separation unit for downstream processing and the transaminases are immobilized separately (onto classical supports) and packed into distinct fixed-bed reactors.
