“…Biotransformation by microorganisms is an important fate of PCP in the environment and contaminated sites. The white rot fungi, which can decompose lignin, can effectively transform PCP and were widely studied for the treatment of PCP-contaminated soil [9] , [10] and wastewater [11] . Dechlorination and methylation were the two major pathways of PCP biotransformation and both led to detoxification of PCP.…”

The occurrence of cytochrome P450 and P450-mediated pentachlorophenol oxidation in a white rot fungus Phanerochaete chrysosporium was demonstrated in this study. The carbon monoxide difference spectra indicated induction of P450 (103±13 pmol P450 per mg protein in the microsomal fraction) by pentachlorophenol. The pentachlorophenol oxidation by the microsomal P450 was NADPH-dependent at a rate of 19.0±1.2 pmol min−1 (mg protein)−1, which led to formation of tetrachlorohydroquinone and was significantly inhibited by piperonyl butoxide (a P450 inhibitor). Tetrachlorohydroquinone was also found in the cultures, while the extracellular ligninases which were reported to be involved in tetrachlorohydroquinone formation were undetectable. The formation of tetrachlorohydroquinone was not detectable in the cultures added with either piperonyl butoxide or cycloheximide (an inhibitor of de novo protein synthesis). These results revealed the pentachlorophenol oxidation by induced P450 in the fungus, and it should be the first time that P450-mediated pentachlorophenol oxidation was demonstrated in a microorganism. Furthermore, the addition of the P450 inhibitor to the cultures led to obvious increase of pentachlorophenol, suggesting that the relationship between P450 and pentachlorophenol methylation is worthy of further research.

“…Some studies reported about the biodegradation of PCP in soil, water and some bioreactors by P. chrysosporium and the application of inoculation with P. chrysosporium to treat hazardous wastes has showed to be effective in PCP degradation and remediation of PSW at laboratory-scales but less information is available about the effect of inoculation, due to lack of further research (Yu et al, 2011).…”

“…The degradation of these compounds by ligninolytic fungi, including white-rot and litter-decomposing fungi has been intensively studied by various researchers. Wood and litter decay fungi are efficient degraders of these PAHs that were showed from the various investigations, they can mineralize PAHs with four and more condensed aromatic rings, in contrast to bacteria and soil fungi (Yu et al, 2011;Pozdnyakova, 2012).…”

Screening was done for the isolation of effective lignin degraders from the forest soil samples, by providing lignin as a carbon source through the enrichment method, which leads to the isolation of 8 effective fungal isolates among 14 isolates. Submerged fermentation was done for the production of ligninolytic enzymes with the effective microorganisms by providing Guiaicol as a carbon source. The assay of laccase, lignin peroxidise activity and specific activity was done after the incubation intervals of 2, 4, 6, 7, 8, 10 and 12 days at 27±2°C under shake culture condition. Partially purified protein content was estimated by using Lowry's method. Pleurotus sp. and Phanerochaetae chrysosporium are more effective at the 2nd and 7th days of incubation for the production of laccase and lignin peroxidases among the effective isolates.

“…The microorganisms are adaptable to adverse conditions and find ways to grow even in challenging environments [55]. Its potential for biotechnological applications are justified by their tolerance to extreme environmental conditions, rapid growth, low cultivation cost [56], and mainly by their enzymes, which can transform a wide variety of nonnatural chemical compounds [57].…”

Contamination by pesticides employed in agriculture has caused serious environmental harm. Pentachlorophenol (PCP) is a phenolic organochlorine compound and a dangerous pollutant which was banned from Brazil since 1985; however, there are still many contaminated areas. This pesticide is a serious problem because it has high toxicity and persistence at the environment due to its resistance to biotic and abiotic degradation. The use of microorganisms as degrading agents is considered an efficient method to reduce the adverse effects of environmental contaminants. It is noteworthy that fungi from marine environment are adapted to extreme conditions, including high chlorine concentrations, and can produce unique enzymes with interesting properties. Therefore, marine-derived fungi have an excellent enzymatic potential for the biotransformation of xenobiotics such as organochlorine pesticides. In this work, fifteen fungi strains isolated from a marine invertebrate, the ascidian Didemnun ligulum, were evaluated according to their ability to grow in solid culture media (3% malt extract agar) in the presence of different concentrations (10, 25, 30, 40, and 50 mg L-1) of PCP. Among the tested strains, nine could grow in at least one concentration, and Trichoderma harzianum CBMAI 1677 showed optimal growth at the higher evaluated concentration (50 mg L-1), showing toxicity resistance and suggesting its potential for biodegradation of PCP. In a later work, it was observed that T. harzia
