摘要：
alpha-Amylase enzyme was immobilized onto gelatin Carrier system. Chromium (III) acetate and potassium chromium (III) sulfate were used as crosslinking agents. Effect of carrier system composition on immobilization was investigated by combining different proportions of carboxymethylcellulase or polyacrylamide with gelatin. Considerable relative activity enhancements were achieved (41% for carboxymethylcellulose-gelatin and 25% for polyacrylamide-gelatin). Reusability's of immobilized enzymes were also investigated. Activities were stable at least for 20 uses.
