Immobilized Peroxidase as a Valuable Tool in the Remediation of Aromatic Pollutants and Xenobiotic Compounds: A Review

The authors attempted to survey literature based on the role of immobilized peroxidases in the treatment and remediation of various types of organic pollutants present in wastewater. Peroxidases from fungal (Caldariomyces fumago, Lentinula edodes, Phanerochaete chrysosporium, Pleurotus pulmonarius, Aspergillus oryzae, Trametes versicolor, Chrysonilia sitophila [TFB-27441]) and plant sources (horseradish, turnip, tomato, soybean, bitter gourd, white radish chayote, and Saccharum uvarum) were immobilized by using different methods of enzyme immobilization (adsorption, covalent attachment, entrapment and micro-encapsulation). Various types of organic and inorganic supports have been considered for the immobilization of peroxidases. These immobilized peroxidase preparations were employed for the oxidative degradation and removal of organic compounds such as phenols, derivative of phenols, anilines, anthracene, benzidine, dyes, 2,4-dimethyldibenzothiophene, 2-chlorobiphenyl, chlorolignins, 4,6-dimethyldibenzothiophene chlorpromazine, 2,4,6-trinitrotoluene, and hydroxylated aromatic compounds in batch processes as well as in different types of continuous reactors at a large scale.
