“…Although the role of individual ligninolytic enzymes in PAH degradation is still not completely understood and some investigators have suggested that the PAH-degrading and lignindegrading systems of white-rot fungi can be distinct (8,14,22) it was shown that both laccase (21,50) and MnP (13,33,44,55) are capable of PAH degradation (oxidation) in the presence of appropriate mediators. No direct conclusion can be drawn about the role of ligninolytic enzymes in PAH disappearance; however, limited PAH degradation by P. ostreatus in Cd at 500 ppm can be due to low MnP activity, and thus, this enzyme is probably responsible for the bulk degradation of PAH compounds by the fungus.…”

The white-rot fungus Pleurotus ostreatus was able to degrade the polycyclic aromatic hydrocarbons ( anthracene (41%), the fungus enhanced the disappearance of less-soluble polycyclic aromatic compounds containing five or six aromatic rings. Although the heavy metals in the soil affected the activity of ligninolytic enzymes produced by the fungus (laccase and Mn-dependent peroxidase), no decrease in PAH degradation was found in soil containing Cd or Hg at 10 to 100 ppm. In the presence of cadmium at 500 ppm in soil, degradation of PAHs by soil microflora was not affected whereas the contribution of fungus was negligible, probably due to the absence of Mn-dependent peroxidase activity. In the presence of Hg at 50 to 100 ppm or Cd at 100 to 500 ppm, the extent of soil colonization by the fungus was limited.

“…Most of the previous studies on biodegradation of PAHs by fungi have focused on white-rot fungi [21 -24]. Boyle et al [25] found that white-rot fungi growing in soil did not degrade significant amounts of PAHs. Fusarium solani, a non-white-rot species, is little known for its ability of HMW-PAHs degradation compared with white-rot fungi [38].…”

“…Most of the previous studies on biodegradation of PAHs by fungi have focused on white-rot fungi [21 -24]. Boyle et al [25] found that white-rot fungi growing in soil could not breakdown significant amounts of PAHs. However, there is limited knowledge about the degradation of PAHs by non-white rot fungi, the aim of this study was to isolate and examine the non-white-rot fungi that could degrade a mixture of four compounds representatives of LMW and HMW-PAHs.…”

Objectives:This study evaluates the ability of a non-white rot fungus strain, HESHAM-1, to degrade a mixture of low (naphthalene and phenanthrene) and high (chrysene and benzo(a)pyrene) molecular weight polycyclic aromatic hydrocarbons (LMW and HMW PAHs). Methods:Strain HESHAM-1 was isolated from oil polluted soil by enrichment method using phenanthrene as the sole source of carbon and energy. The strain showed the ability to tolerate and degrade a mixture of both low and high molecular weight PAHs. In the presences of LMW-PAHs (naphthalene and phenanthrene) as co-substrate, chrysene and benzo(a)pyrene (HMW-PAHs) were, respectively degraded by the fungus strain HESHAM-1 which was confirmed by GC-MS analyses. Results:The degradation rate was found as 84.82% for naphthalene, 40.09% for phenanthrene, 57.84% for chrysene and 71.06% for benzo(a)pyrene at the end of 10 days. This is the first report describing the biodegradation of a mixture of four PAH compounds by non-white rot fungus strain HESHAM-1 isolated from Egyptian oil-polluted soil. The fungus strain HESHAM-1 was identified by morphological characteristics and molecular genetics technique based on PCR amplification and sequencing of the internal transcribed spacers (ITSs) of the rDNA region and intervening 5.8S rRNA gene. Blast result and phylogenetic analysis of gene sequencing suggested that strain HESHAM-1 was closely related to Fusarium solani with 100% sequence identity. Conclusion:The present study clearly demonstrates that, strain HESHAM-1 could be used to remove the crude oil from the environment.

“…These variations depended on various factors such as the initial concentration of the target pollutant or the culture conditions such as type of medium, pH or temperature and the bioavailability of the pollutant. It was also observed that the percentage of PAH biodegradation was significantly higher in liquid than in solid culture conditions, probably due to the decreased PAH availability in solid medium [34,35] . Even so, there are some studies on solid cultures that demonstrate higher degradation rates (Table 1), probably due to the effect of the different factors mentioned above [14,17,36] .…”

The efficiency of cork waste in adsorbing aqueous polycyclic aromatic hydrocarbons (PAHs) has been previously reported. Biodegradation of contaminated cork using filamentous fungi could be a good alternative for detoxifying cork to facilitate its final processing. For this purpose, the degradation efficiency of anthracene by three ligninolytic white-rot fungi (Phanerochaete chrysosporium, Irpex lacteus and Pleurotus ostreatus) and three non-ligninolytic fungi which are found in the cork itself (Aspergillus niger, Penicillium simplicissimum and Mucor racemosus) are compared.Anthracene degradation by all fungi was examined in solid-phase cultures after 0, 16, 30 and 61 days. The degradation products of anthracene by P. simplicissimum and I. lacteus were also identified by GC-MS and a metabolic pathway was proposed for P. simplicissimum.Results shown that all the fungi tested degraded anthracene. After 61 days of incubation approximately 86%, 40% and 38% of the initial concentration of anthracene (i.e. 100 µM) was degraded by P. simplicissimum, P. chrysosporium and I. lacteus, respectively.The rest of the fungi degraded anthracene to a lesser extent (< 30%). As a final remark, the results obtained in this study indicate that P. simplicissimum, a non-ligninolytic fungi characteristic of cork itself, could be used as an efficient degrader of PAHcontaminated cork.
