Taking this to the next level, it would be of particular interest to immobilize enzymes directly onto active membrane supports, and hence to develop bifunctional membranes allowing to simultaneously host the immobilized enzymes and perform the product separation to intensify the transamination process. The immobilization of enzymes onto polymeric membranes has already been reported with lipases, carbonic anhydrase, and glucose oxidases . Recently, Howdle et al. developed an electrospun polycarvone acrylate diepoxide/polyvinylidene fluoride (PCADE/PVDF) membrane and exploited it for the immobilization of the TA from Halomonas Elongata (HeWT) . This epoxy-functionalized membrane allowed 61.0 % immobilization yield and 43.6 % of specific activity recovery (no TA leaching), paving the way for potential application in combined reaction-separation processes.
