“…The white rot fungi, Phanerochaete chrysosporium, Trametes versicolor, Pleurotus ostreatus, Bjekandera sp, and the brown-rot fungi Neolentinus lepideus were reported to be able to degrade various PAHs (Matsubara et al, 2006;Verdin et al, 2004). Other fungi such as non lignolytic fungi, Coniothyrium sp., Penicillilium sp., Cunninghamella elegrans, Trichoderma viride, Fusarium solani, Phialophora alba, have exhibited a significant potential to metabolize various PAHs to polar metabolites (Verdin et al, 2004;Potin et al, 2004;Ravelet et al, 2000). Non ligninolytic fungi are major group of fungi that metabolize various PAHs by cytochrome P450 monooxygenase, epoxide hydrolase and dioxygenase.…”

Chrysene is a class of organic compounds, arranged in four benzene rings, and a polycyclic aromatic hydrocarbon (PAH), It has been found to have a variety of toxicity, mutagenicity, teratogenicity, and carcinogenicity on microorganisms, plants and animals in environment. Nowadays, the most attention on degradation of PAHs is investigating degradation of high-molecular-weight molecules. However, microbes which have ability to degrade PAHs containing more than three benzene rings are more difficult to be obtained. In order to provide chrysene degrading fungi, this study was conducted for screening, and isolating the fungi from soil, and hence investigating the selected fungi having high chrysene degradation activity. From the 62 soil samples collected from Matsuyama-Japan, 92 isolates were found and 20 isolates of them grew well in Malt extract media contaminated with chrysene (covered up 90%). Among them, a fungus, Fusarium sp. has the highest activity to degrade chrysene compared to others screened fungi. This fungus was evaluated further on liquid medium from distilled water and sea water to confirm their validity in degrading chrysene. The result showed that Fusarium sp. F092 degraded 48% of chrysene, where the chrysene degradation showed no differences at salinity of 35 o / oo . The effect of variation of enzymes activities on incubation times was evaluated simultaneously. When the fungus was grown in a liquid culture, the highest activity of 1,2-dioxygenase reached 203.5 UL -1 were observed on 30 days incubation and 29.7 Ul -1 for 2,3-dioxygenase on 40 days incubation. The products of chrysene degradation by Fusarium sp. F092 are, 1-hydroxy 2-napthoic acid and catechol. In conclusion, Fusarium sp. F092 shows a high potential activity degrade PAHs contamination .

“…[50] showed that P. ostreatus produced laccase during cultivation in BRM independently of the presence of pyrene, whereas fluoranthene and benzo[a]pyrene inhibited laccase production by about 1.5 times. Other authors found that benzo[a]pyrene has no remarkable effect on laccase production by the fungi Fusarium solani and F. oxysporum [53], or by T. versicolor [49]. We found that among the four-ring PAHs, pyrene and fluoranthene increased laccase production but chrysene was substantially inhibitory.…”

Influence of PAHs on ligninolytic enzymes of the fungus Pleurotus ostreatus D1

Polycyclic aromatic hydrocarbons (PAHs), their derivatives, and their degradation products were assayed for the ability to enhance activities of ligninolytic enzymes (laccase and versatile peroxidase) of the fungus Pleurotus ostreatus D1. The activities of both laccase and versatile peroxidase were induced by the PAHs, their derivatives, and their degradation products. Laccase was produced mostly in the first 7-10 days, whereas the production of versatile peroxidase began after 5-7 days of cultivation. Non-denaturing PAGE showed the presence of additional forms of laccase and versatile peroxidase in the presence of the xenobiotics in the cultivation medium. The difference in the production time for these enzymes may reflect that laccases are involved in the first stages of PAHs degradation and that versatile peroxidase can be necessary for oxidation of some degradation products. This is the first report on versatile peroxidase induction by PAHs and their derivatives.
