Solid-Phase Treatment of a Pentachlorophenol-Contaminated Soil Using Lignin-Degrading Fungi

摘要

The abilities of three lignin-degrading fungi, Phanerochaete chrysosporium, P.sordida, and Trametes hirsuta to deplete pentachlorophenol (PCP) from soil contaminated with PCP and creosote were evaluated. A total of seven fungal and three control treatment were examined for their effect on the PCP concentration over eight weeks in two complementary field treatbility studies at the Brookhaven Wood Preserving facility in Brookhaven, MS. The fungi were applied to the soil as pure or mixed cultures at several different inoculum loading levels (inoculum:soil, w/w). The results of the study demonstrate that bioaugmentation using lignin-degrading fungi has the potential to be a viable treatment option for remediation of PCP-contaminated soils.
