Cooxidation of Carcinogenic Benzo(a) Pyrene and Phenols by Horseradish Peroxidase (Armoracia lapathifolia)

Abstract

Suwimury:The catalytic activity of horseradish (Avnroracia Zapathifolia) peroxidase in the oxidation reactions of benao(a)pyrene (BP) and phenols, separately and in admixture, has been studied. Experiments were carried out with model phenols from industrial sewage (phenol, m-. p-cresols, catechol, hydroquinoiie, resorcinol, orcinol), keeping to the real csoricentration ratio of reagents, 0.5 mM for phenols, 0.1 nM for benzo(a)pyrene.The total oxidation process for all reagents tested is described by the second-order formal The resiilts obtained permit a supposition that peroxidase containing plants are capable of simultaneously transforming carcinogenic benzo(a)pyrene and toxic phenols in water reservoirs and in the soil. thus promoting the detoxication of environment.
