Phytoremediation is an interesting strategy because of the ability of some plants to adsorb, accumulate and/or tolerate high concentrations of pollutants such as heavy metals, organic compounds and radioactive elements. In the particular case of phenolic compounds, two different methods are usually employed; (a) the phytoextraction, in which roots capture these organic compounds which are accumulated in roots, stems and leaves and can be afterwards precipitated and concentrated; (b) the phytodegradation, whereby aquatic and terrestrial plants capture, store and degrade organic compounds to less toxic or harmless byproducts [1].In the present work, the phytodegradation of 4-chlorophenol using different peroxidases i.e: two Total Peroxidase Extracts (TPE), obtained from turnip (Brassica napus) and tobacco (Nicotiana tabacum cv. Wisconsin) hairy roots (HR) respectively, and a commercial soybean peroxidase (SBP), has been investigated. In addition, a complete characterization and a comparative study of these peroxidases have been carried out.
