Amylase immobilized on a reticulated polymer containing rosin group

摘要

Two polymer carriers of reticulated rosin group were synthesized to immobilize amylase in this paper, the nature of immobilized amylase was inspected. Results indicated that the optimal temperature for immobilize amylase was 40 °C, the optimal pH was 6.4, thermal stability and acid-base stability was superior to free amylase, 17% of the amylase activity existed after been used six times.
