Abstract:
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 fromwater sample and 17 fromsediments; 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.
