3.6 Reuse stability
The reuse stability of
immobilized enzymes was investigated, as shown in Fig.7. After 7
consecutive cycles of reactions, the residual activities of
DAADH/ZIF-8/RGO and DAADH/ZIF-8 were 64.3% and 45.6%, respectively.
Enhanced stability of DAADH/ZIF-8/RGO probably as DAADH tends to combine
with the hydrophobic surface of RGO. Hydrophobic effect greatly improves
enzyme recovery activity and shows better reuse stability than
immobilization by DAADH/ZIF-8.
