When CduCPR and TgGDH are confined in the sodium alginate (SA)-coated hNFs [CduCPR/TgGDH-Ca3(PO4)2], both of them have excellent reusability and high stability. The SA-coated hNF reactor successfully catalyzes the asymmetric synthesis of (R)-PL, which exhibits satisfactory stereoselectivity and promotes reusability in repeated batches. The SA coating functioned to competently immobilize the coenzyme NADP+ on the CduCPR/TgGDH-Ca3(PO4)2 hNFs, which maintains the maximum bioactivity to synthesize (R)-PL without exogenous coenzyme addition.
