Biodegradation of Pentachlorophenol (PCP) - Treated Ammonium Boxes Using White-Rot Fungi

Abstract

The lignin-degrading fungi Phanerochaete chroysosporium, P. sordida, Trametes hirsuta, and Ceriporiopsis subvermispora were evaluated for their ability to decrease the concentration of pentachlorophenol (PCP) and to cause dry weight loss in PCP-treated wood. Hardwood and softwood materials from PCP- treated ammunition boxes that were chipped to pass a 3.8-cm screen were used. All four fungi caused significant weight losses and decreases in the PCP concentration. The largest PCP decrease (84%) was caused by T. hirsuta, and the smallest decrease was caused by C. subvermispora (37%). Decreases of PCP by P. chrysosporium and P. sordida averaged 59% and 57%, respectively. PCP decreases caused by Phanerochaete spp. were not significantly affected by wood type or sterilization and were primarily due to methylation of PCP that resulted in accumulation of pentachloroanisole.
