Pentachlorophenol (PCP) transformation and concentration of tetrachlorohydroquinone (TCHQ) after incubation of PCP and microsomal fractions of Phanerochaete chrysosporium from potato dextrose broth (PDB) cultures.

Mean ± standard deviation of the mean, n = 3aThe reaction mixtures were incubated at 37°C for 10 hbThe microsomal fraction of 37.5 mM PCP-induced cells was utilized.cThe microsomal fraction of non-induced cells was utilized. ND, P450 was not detectable.dThe concentration of PCP transformed and transformation rate of PCP were calculated according to concentrations of residual PCP in the sample and the sterile control after 10-h incubation.eND, not detectable (µM).
