Item Comperative study of catalase immobilization on chitosan, magnetic chitosan and chitosan-clay composite beads(2013) Başak E.; Aydemir T.; Dinçer A.; Becerik S.Ç.Catalase was immobilized on chitosan and modified chitosan. Studies were carried out on free-immobilized catalase concerning the determination of optimum temperature, pH, thermal, storage stability, reusability, and kinetic parameters. Optimum temperature and pH for free catalase and catalase immobilized were found as 35°C and 7.0, respectively. After 100 times of repeated tests, the immobilized catalases on chitosan-clay and magnetic chitosan maintain over 50% and 60% of the original activity, respectively. The ease of catalase immobilization on low-cost matrices and good stability upon immobilization in the present study make it a suitable product for further use in the food industry. © 2013 Informa Healthcare USA, Inc.
