Application of immobilized GPAp by recycling to maintain the stability of Ala-Gln production. a The catalytic activities of GPAp were detected daily by HPLC during the 5 days which GPAp was stored at the optimal reaction pH and temperature (8.5 at 28 °C). b The catalytic activities were detected and compared among free GPAp with one unit of OD600, immobilized GPAp with one unit of OD600 and immobilized GPAp with double OD600. c The reusability of immobilized GPAp was detected at optimum conditions for recycling 10 times
