Gerden radish (Raphanus sativus L.) peroxidase in the detoxication of hazardous aromatic wastes

Abstract

Peroxidase used in oxidation of a wide range of aromatic chemicals. We used a domestic source of peroxidase (garden radish, Raphanous sativus L.) to treat the following hazardous chemicals: phenol, aniline, bnzidine, alachlor, butachlor, acid red 88 and acid blue 62. Crude enzyme removed the above-mentiond chemicals more efficiently in 24 hr treatment. Changes in pH cause a removal efficacy change, for example lowering pH from 7 to 4.0 for phenol treatment increased removal from 0.5% to 100% for crude enzyme. In conclusion, Garden radish is a good substitute for horseradish in order to treat aromatic wastewaters.
