Nine fungal strains showing ability of cortexolone hydroxylation to epicortisol and/or cortisol were screened in this work for anthracene and phenanthrene elimination (250 mg/l). All of the strains ( Cylindrocladium simplex IM 2358, C. simplex IM 2358/650, Monosporium olivaceu m IM 484, Curvularia lunat a IM 2901, C. lunata IM 2901/366, C. tuberculat a IM 4417, Cunninghamella elegans IM 1785, C. elegans IM 1785/21Gp, C. elegans IM 1785/10Gi) significantly removed anthracene and phenanthrene. During incubation with anthracene formation of intermediate products was observed. The amount of the main intermediate product, identified as 9,10‐anthraquinone, was not greater than 22.2% of the anthracene introduced to the fungal cultures. C. elegans IM 1785/21Gp was the best degrader of both anthracene and phenanthrene, removing 81.6 and 99.4% of these compounds after 7 days, respectively. Phenanthrene removal by C. elegans IM 1785/21Gp was preceded by PAHs accumulation in mycelium and growth inhibition. Elimination of phenanthrene started after one day of incubation and was related to the fungus growth.
