We had reported engineering of the heme monooxygenase cytochrome P450cam from Pseudomonas putida with the F87W/Y96F/L244A/V247L mutations for the oxidation of pentachlorobenzene (PeCB), a recalcitrant environmental contaminant, to pentachlorophenol. In order to provide further insights into P450 structure, function and

There are no longer any large scale uses of pentachlorobenzene (PeCB). Current emissions of PeCB to the environment are estimated to be about 121000kgy(-1), based on published information. The largest sources appear to be combustion of solid wastes, 32000kgy(-1), biomass

The coking process is considered to be a potential source of unintentionally produced persistent organic pollutants (UP-POPs). However, intensive studies on the emission of UP-POPs from the coking industry are still very scarce. Emission of polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs), dioxin-like polychlorinated
