“…Among them, white-rot fungi are highly tolerant to toxic compounds and are widely used in biodegradation techniques [71]. These fungi are effective in the degradation of PCP by having ligninolytic and peroxidase enzymes [89] that act by generating free radicals [90], which can also degrade a variety of recalcitrant pollutants ( Figure 3) The ligninolytic extracellular activity of some fungal enzymes is considered a promising method for PCP degradation [92,94]. The Phanaerochaete chrysoporium [95,96], as well as Phlebia brevispora [97], Phlebia radiata, Trametes versicolor [98], and Mucor plumbeus [99] showed great ability to degrade organopollutants (including PCP).…”

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

Pentachlorophenol (PCP) is an extremely dangerous worldwide pollutant due to its high toxicity towards all organisms. It has been introduced into the environment mainly as a wood preservative, biocides and from the bleaching of paper or tissues. The use of PCP indiscriminate has led to the contamination of water and soil systems. Many countries have specific regulations, guidelines or procedures for the management and disposal of PCP but the most common methods are: adsorption with activate carbons, incineration in an approved and secure area, closed in sealed containers and biological degradation. PCP depletion can occur either by abiotic processes such as: absorption, volatilization and photo degradation or by biotic degradation. One of the main studies focused on remediation using plants, animals and microbial communities. Aerobic and anaerobic microorganisms can degrade PCP under a variety of conditions and at different PCP concentrations. Bacterial strains such as Pseudomonas sp., Sphingomonas sp., Arthrobacter sp., Mycobacterium sp., Flavobacterium sp., Serratia sp. and Bacillus sp., and fungal cultures as Trametes sp., Phanerochaete sp., Anthracophyllum sp., Armillaria sp., Bjerkandera sp., Ganoderma sp., Lentinula sp., Penicillium sp, Trichoderma sp., Rhizopus sp. and Plerotus sp. showed various rates and extent of PCP degradation. This review focuses on PCP degradation by various aerobic and anaerobic microorganisms with emphases on the biological and chemical aspects. Furthermore we will analyze intermediate products, processes and enzymes involved in the degradation of PCP in different environmental conditions and at various PCP concentrations
