Title: | Lentinus (Panus) tigrinus augmentation of a historically contaminated soil: matrix decontamination and structure and function of the resident bacterial community | Authors: | Federici, Ermanno Giubilei, Maria Angela Cajthaml, Tomáš Petruccioli, Maurizio D'Annibale, Alessandro |
Keywords: | Lentinus (Panus) tigrinus;Mycoremediation;Aromatic hydrocarbons;Historical contamination;Biodiversity;Microbial community | Issue Date: | 2011 | Publisher: | Elsevier | Source: | Federici E., et al. 2010. Lentinus (Panus) tigrinus augmentation of a historically contaminated soil: matrix decontamination and structure and function of the resident bacterial community. "Journal of Hazardous Materials" 186: 1263-1270. | 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. |
