General description

2,4-Dichlorophenol is anthropogenic organic compound and a common water and soil pollutant. It is precursor required for the synthesis of herbicides:2,4-dichloro- and 2,4,5-trichloro-phenoxyacetic acids and wood preservative: pentachlorophenol.

Application

2,4-Dichlorophenol was used to study the degradative pathway of 2,4-dichlorophenol by Phanerochaete chrysosporium. It was used to study the competitive sorption of anthropogenic organic compounds in soils.

Under secondary metabolic conditions the white rot basidiomycete Phanerochaete chrysosporium mineralizes 2,4-dichlorophenol (I). The pathway for the degradation of 2,4-dichlorophenol (I) was elucidated by the characterization of fungal metabolites and of oxidation products generated by purified lignin peroxidase and manganese

In this study, the H2S donor, sodium hydrosulfide (NaHS) was used to pretreat Phanerochaete chrysosporium in order to improve its ability to degrade 2,4-dichlorophenol (2,4-DCP). When pretreated with 100μM NaHS, P. chrysosporium was able to degrade 2,4-DCP completely in 24h
