“…As for seawater, the dominance of Ascomycota in contaminated sediments is in agreement with literature data, where Basidiomycota have never been found (Sadaba and Sarina, 2010;Salvo et al, 2005). The highest fungal load in sediments was observed for C. cladosporioides: this species, found also in the surrounding polluted water, has been already reported from extreme salinity environments as Saharan salt flat (Jaouani et al, 2014) and in the desert dust (Griffin, 2007).…”

Bioremediation of marine environment could be the response to oil spills threats. In the present study the fungal community from a Mediterranean marine site chronically interested by oil spills was investigated. Sixty-seven taxa were isolated from water sample and 17 from sediments; for many of the identified species is the first report in seawater and sediments, respectively. The growth of 25 % of the fungal isolates was stimulated by crude oil as sole carbon source. Four strains were selected to screen hydrocarbons degradation using the 2,6-dichlorophenol indophenol (DCPIP) colorimetric assay. A. terreus MUT 271, T. harzianum MUT 290 and P. citreonigrum MUT 267 displayed a high decolorization percentage (DP ≥ 68 %). A. terreus displayed also the highest decreases of hydrocarbons compounds (up to 40 %) quantified by gas-chromatography analysis.These results suggest that the selected fungi could represent potential bioremediation agents with strong crude oil degradative capabilities.

“…Sediment sample displayed a total fungal load (about 4,000 CFU g -1 dw) higher than that (50-200 CFU g -1 dw) reported in chronically contaminated marine sediments in the north of Italy (Salvo et al, 2005), but much lower (2.4 x 10 4 g -1 dw) than sites interested by one oil spill event in…”

“…Rates detailed refer to removal of the first named PAH (in bold) in the mixture PAH (present as single compound/mixture) profound effect of the PAH treatments on fungi. Ligninolytic and non-ligninolytic fungi have been reported to play an important role in PAH degradation in natural environments, particularly in the initial degradation of high molecular weight PAHs (Salvo et al 2005). Fungi often metabolize PAHs as a means of detoxifying these compounds rather than use them as a source of carbon.…”

Contaminated sites generally contain complex mixtures of pollutants. Development of effective bioremediation strategies for contaminated soils requires knowledge of the response of soil microbial communities to such mixtures. This study provides information on the degradation of different mixtures of three priority pollutants in soil with a history of polycyclic aromatic hydrocarbon contamination and examines the response of soil bacterial and fungal communities to the presence of these pollutants as sole contaminants or as part of a mixture. This is one of few studies to-date to compare the effects of single compounds and pollutant mixtures on more than one soil microbial community.

“…However, research indicates that in soil habitats, filamentous fungi offer certain advantages over bacteria for bioremediation (Potin et al 2004;Salvo et al 2005). Fungi are seen as potential soil remediation organisms (Gramss et al 1999), especially in arid and semi-arid environments (Kashangura et al 2006).…”

Some strains of white rot fungi, non-lignolytic fungi and litter-decomposing basidiomycetes have been recognized as PAH degraders. The purpose of our research was to enlarge the scope of PAH-degrading fungi and explore the huge endophytic microorganism resource for bioremediation of PAHs. In this study, phenanthrene was used as a model PAHs compound. Nine strains of endophytic fungi isolated from four kinds of plant from Eupharbiaceae were screened for degradation of phenanthrene. The endophytic fungus Ceratobasidum stevensii (strain B6) isolated from Bischofia polycarpam showed high degradation efficiency and was selected for further studies. Into the fungal culture, 100 mg l(-1) phenanthrene was added, and after 10 days of incubation, about 89.51% of the phenanthrene was removed by strain B6. Extracellular ligninolytic enzyme activities of strain B6 were tested. The results showed that manganese peroxidase [MnP] was the predominant ligninolytic enzyme and that its production was greatly induced by the presence of phenanthrene. To confirm the involvement of MnP in phenanthrene degradation, promotion and inhibition studies on MnP in different concentration level of Mn(2+) and NaN(3) were performed. Additionally, fungal mycelium-free and resuspended experiments were carried out. The results showed no apparent correlation between MnP activity and phenanthrene degradation. The mycelium and fresh medium were the crucial factors affecting the degradation of phenanthrene. To date, this is the first report on PAH degradation by Ceratobasidum stevensii. This study suggests that endophytic fungi might be a novel and important resource for microorganisms that have PAH-degrading capabilities.
