Natural polymers such as alginate, pectin, chitosan etc. were used as carriers for the immobilization of different types of enzymes. Among investigated enzymes, peroxidases hold a special place. Immobilized enzymes are frequently used in phenol removal reactions. In this research horseradish peroxidase was immobilized within alginate micro-beads. This natural polymer was previously oxidized with sodium periodate and modified with tyramine hydrochloride. Percent of oxidation was varied from 2.5 mol% to 10 mol%, and an increase in specific activity was noticed with increasing the oxidation percent. Immobilized peroxidases showed satisfactory stabilities after 10 days of storage. Phenol concentration in a batch reactor decreased during its oxidation with horseradish peroxidase immobilized on tyramine-alginate hydrogels.
