Abstract: 
The ability of Lentinus tigrinus to grow and to degrade persistent aromatic hydrocarbons in aged contaminated
soil was assessed in this study. L. tigrinus extensively colonized the soil; its degradation
activity after 60 d incubation at 28 ◦C, however, was mostly limited to dichloroaniline isomers, polychlorinated
benzenes and diphenyl ether while the fungus was unable to deplete 9,10-anthracenedione
and 7-H-benz[DE]anthracene-7-one which were the major soil contaminants. Although clean-up levels
were limited, both density of cultivable heterotrophic bacteria and richness of the resident bacterial
community in L. tigrinus microcosms (LtM) increased over time to a significantly larger extent than the
respective amended incubation controls (1.9×109 CFU g−1 vs. 1.0×109 CFU g−1 and 37 vs. 16, respectively).
Naphthalene- and catechol 2,3-dioxygenase gene copy numbers, however, decreased over time
at a higher rate in LtMthan in incubation controls likely due to a higher stimulation on heterotrophs than
xenobiotics-degrading community members.
