| Abstract: | Ligninolytic white rot fungus, Phanerochaete chrysosporium, isolated from soil sample of petroleum refinery, was
used for degradation of five polycyclic aromatic hydrocarbons (PAHs: acenaphthene, anthracene, phenanthrene, fluoranthene
and pyrene), simultaneously and individually in sterile and unsterile soil. For maximum biodegradation, after 42 days of
incubation, optimum conditions were pH 7.0, 30°C and 5μg/g PAHs concentration. In sterile soil, degradation in 42 days of
incubation of five PAHs was as follows: phenanthrene, 98.96; anthracene, 92.6; pyrene, 92.2; acenaphthene, 83.8; and
fluoranthene, 79.8%. In unsterile soil, PAHs degradation was low (38.94-62.89%). |
