“…Pentachloroanisole formation from PCP metabolism is well established (Lamar and Dietrich 1990;Okeke et al 1997;Tuomela et al 1999;Chung et al 2001). Also the conversion of 3,4-and 2,4-dichlorophenols to their respective anisoles has been reported (Coulter et al 1993;Deschler et al 1998). During degradation of chlorinated phenols, chlorinated hydroquinone intermediates are occasionally subject to methylation, leading to the formation of chlorinated 1,4-dimethoxybenzenes or chlorinated 4-methoxyphenols (Valli and Gold 1991;Reddy et al 1998;Reddy and Gold 2000).…”

Chlorophenols have been introduced into the environment through their use as biocides and as by-products of chlorine bleaching in the pulp and paper industry. Chlorophenols are subject to both anaerobic and aerobic metabolism. Under anaerobic conditions, chlorinated phenols can undergo reductive dechlorination when suitable electron-donating substrates are available. Halorespiring bacteria are known which can use both low and highly chlorinated congeners of chlorophenol as electron acceptors to support growth. Many strains of halorespiring bacteria have the capacity to eliminate ortho-chlorines; however only bacteria from the species Desulfitobacterium hafniense (formerly frappieri) can eliminate para-and meta-chlorines in addition to ortho-chlorines. Once dechlorinated, the phenolic carbon skeletons are completely converted to methane and carbon dioxide by other anaerobic microorganisms in the environment. Under aerobic conditions, both lower and higher chlorinated phenols can serve as sole electron and carbon sources supporting growth. The best studied strains utilizing pentachlorophenol belong to the genera Mycobacterium and Sphingomonas. Two main strategies are used by aerobic bacteria for the degradation of chlorophenols. Lower chlorinated phenols for the most part are initially attacked by monooxygenases yielding chlorocatechols as the first intermediates. On the other hand, polychlorinated phenols are converted to chlorohydroquinones as the initial intermediates. Fungi and some bacteria are additionally known that cometabolize chlorinated phenols.

“…The removal capacity of Alternaria destruens F10.81 and Fusarium pseudonygamai F576 was compared with that of Phanerochaete chrysosporium, which is the most studied fungi for PAHdegradation (Cao et al, 2020). It serve often as control fungi even for comparing PAH-removal capacity from strains belonging to different phyla (Cao et al, 2020), because it exhibit the capacity to degrade a broad range of organic compounds (Deschler et al, 1998;Duran et al, 2002), including several PAHs (Pointing, 2001). Under our conditions P. chrysosporium presented low rates of PAHs removal (< 30%), just above to that exhibited by F. pseudoygamai F5.76 and around 3 times less to that observed for A. destruens F10.81 (Fig.…”
