Chlorophenols degradation by catalytic siderophores from white rot fungi Phanerochaete chrysosporium ME 446

摘要

In this work the reactions between parachlorophenol (p-CP), 2,4-DCP (2,4-dicholorphenol), 2, 4, 6-TCP (2, 4, 6-trichlorophenol), pentachlorophenol PCP and fungal siderophores (FS), from Phanerochaete chrysosporium ME 446 (FS-Pc) were investigated. Furthermore, Fention reaction systems by using iron chelates in the ame iron concentration,, [DTPA-Fe(II)/H_2O_2] and [EDTA-Fe(II)H_2O_2] and free iron as [Fe(II)H_2O_2], [Fe(III)/H2O2] were also carried out to compare with [FS-Pc/Fe(II)/H_2O_2] reaction. Our results indicate that FS-Pc can degrade all the testd chlorinated compounds. Moreover the PS-Pc reaction was more effective than EDTA, DTPA and Fe(II) reactions.
