| Summary: | This paper describes the biocatalytic performance of soybean peroxidase enzyme to oxidize aqueous aromatic pollutants such as organophosphorus pesticides and polycyclic aromatic hydrocarbons (PAHs), and flavonoids from agro-industrial wastes. The conversions achieved were for the pesticides terbufos (14%) and dimethoate (30% conversion); for HPAs such as azulene (32%), 9-methyl anthracene (22%); anthracene, pyrene (29% each), and carbazole (18%); and for flavonoids such as ferulic acid (99%), quercetin (98%), rutin (50%) and naringin (10%). The tests were carried out on model samples and on simulated samples of contaminated effluents. In addition, the effect of pH and temperature on the enzyme activity was studied, being active from pH 3 to 6, and from 25 ˚C to 80 ˚C. The above concludes that soybean peroxidase is a good candidate for more comprehensive studies for possible application in effluents treatment containing aromatic pollutants
