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

2,4-Dichlorophenol (2,4-DCP) is a ubiquitous environmental pollutant categorized as a priority pollutant by the United States (US) Environmental Protection Agency, posing adverse health effects on humans and wildlife. Bioremediation is proposed as an eco-friendly, cost-effective alternative to traditional physicochemical remediation

The Pd/FeFe(3)O(4) nanocomposites showed higher dechlorination efficiency of 2,4-dichlorophenol (2,4-DCP) rather than bare Pd/Fe nanoparticles in the batch dechlorination experiments. nFe(3)O(4) provided a convenient way to recycle the nanocomposites with an external magnetic field and significantly enhanced 2,4-DCP dechlorination. 2.0

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
