Screening filamentous fungi isolated from estuarine sediments for the ability to oxidize polycyclic aromatic hydrocarbons
Nineteen. lamentous fungi, isolated from estuarine sediments in Brazil, were screened for degradation of polycyclic aromatic hydrocarbons (PAH). The fungal isolates were incubated with pyrene. The cultures were extracted and metabolites in the extracts were detected by high performance liquid chromatography (HPLC) and u.v. spectral analyses. Six fungi were selected for further studies using [4,5,9,10-C-14] pyrene. Cyclothyrium sp., Penicillium simplicissimum, Psilocybe sp., and a sterile mycelium demonstrated the ability to transform pyrene. Cyclothyrium sp. was the most efficient fungus, transforming 48% of pyrene to pyrene trans-4,5-dihydrodiol, pyrene-1,6-quinone, pyrene-1,8-quinone and 1-hydroxypyrene. This fungus was also evaluated with a synthetic mixture of PAH. After 192 h of incubation, Cyclothyrium sp. was able to degrade simultaneously 70, 74, 59 and 38% of phenanthrene, pyrene, anthracene and benzo[a]pyrene, respectively.19439940
