Abstract: Porous starch graft copolymers(PSGC) beads were synthesized and their proper-ties were studied. The PSGCbeads prepared have good mechanical properties and high porosity(about 30%-40%), the pore size is about 19. 5 nm. The PSGCbeads are stable in the range of pH3.13 as well as in boiling water. They contain large amount of active groups making them suitable for use as support material for immobilized enzymes.

Key words: Porous starch graft copolymer beads, Support of immobilized enzymes, Glucoamylase
