摘要: Pilot-scale constructed wetlands were used to treat water contaminated by polycyclic aromatic hydrocarbons (PAHs), particularly fluoranthene, and the possible role of fungi present in these ecosystems was investigated. A total 40 fungal species (24 genera) isolated identified from samples (gravel sediments) a wetland control wetland. All them assayed for their ability remove anthracene (AC) fluoranthene (FA) liquid medium. FA degraded efficiently 33 while only 2 able AC over 70%. selection 10 strains micromycetes belonging various taxonomic groups further investigated degradation, toxicity assays phenoloxidases (POx) detection. Interesting not previously reported revealed (Absidia cylindrospora, Cladosporium sphaerospermum, Ulocladium chartarum). They all highly degrade PAH-model compounds chosen. An interesting inducibility noted chartarum. Degradative related extracellular POx activity. This study may contribute improvement treatment, which be enriched efficient fungi.
