Polyethylene glycol was found to enhance adsorption of Bacillus subtilis OC-amylase on starch in optimum concentration 10 % (w/w). Degree of adsorption at 12°C was increased from 83 to 98 % and from 30 to 81% for cross-linked and raw starch, resp. Higher sorption capacity and easy desor~otion of ~-a
## Abstract **BACKGROUND:** A malto‐oligosaccharide forming α‐amylase from __Bacillus subtilis__ KCC103 immobilized in calcium alginate beads was repeatedly used in batch processes of starch hydrolysis. The degree of starch degradation and operational stability of the immobilized system were optim
