Abstract
The influences of temperature, soil moisture potential and initial pH on the biotransformation of pentachlorophenol (PCP) by the lignicolous fungi Lentinula edodes and Phanerochaete chrysosporium were examined. At 10°C, L. edodes was more effective in degrading PCP (P < 0.05) than P. chrysosporium. At 15°C similar results were obtained for the two fungi. The highest levels of degradation occurred for both fungi at 25°C. With P. chrysosporium, the extent of PCP elimination was directly related to soil moisture content and optimal at approximately 47%. With L. edodes, in contrast, the process was inversely related to moisture content and maximal at 26%. The initial soil pH also had a marked influence, and pH 4.0 was optimal for both fungi.
