Abstract

Sucrose phosphorylase fromLeuconostoc mesenteroides was immobilbilized by covalent linkage to several supports, and the specific activity recovery was 2-11%. The enzyme adsorbed onto DEAE-cellulose re tained about 18% specific activity and was stable over eight months. The optimum pH (7.0) and temperature (30°C) did not change after immobilization. Also there was no improvement of thermal stability, and Km for sucrose and phosphate was lower compared to the soluble enzyme.
