Abstract Sixty-two rotted wood and soil samples were used to screen for chrysene-degrading fungi. A strain of Fusarium, named F092, was identified as most capable of degrading chrysene. F092 was active under saline and nonsaline conditions, breaking down 48\% of the chrysene in 30 d. The percentage of chrysene degraded did not change at 35‰ salinity with pH 8.2 in solid and liquid cultures. The degradation under saline conditions increased about 0.6- and 2.1-fold in cultures with polypeptone and Tween80, and 0.03-fold in agitated cultures. F092 secreted nonligninolytic enzymes named 1,2-dioxygenase and 2,3-dioxygenase. The level of 1,2-dioxygenase activity reached 203.5 U L(-1) at 30 d and that of 2,3-dioxygenase activity, 29.7 U L(-1) at 40 d. The degradation pathway was clarified from the intermediates produced; chrysene 1,2-oxide, chrysene trans-1,2-dihydrodiol, 1-hydroxy 2-naphtoic acid, and catechol. F092 is a potential degrader of chrysene for bioremediation. Copyright © 2012 The British Mycological Society. Published by Elsevier Ltd. All rights reserved.
