HMTC The biodegradative abilities of the white rot fungus, Phanerochaete chrysosoporium, towards carbon-14 labeled polychlorinated organic chemicals was studied in nutrient nitrogen-deficient culture medium. Degradation rates increased as a function of chemical concentrations and were higher for mixtures than for pure chemicals. Only 2% of pure napthalene but 32% of napthalene present in coal tarcontaminated soil was mineralized by P. chrysosporium in 30 days. Pentachlorophenol at concentrations above 4 ppm was lethal to P. chrysosoporium cultures initiated with spores but not to cultures initiated with mycelia. P. chrysosoproium was able to grow in the presence of 300 ppm 1,1,1trichloro-2,2-bix(4-chlorophenyl)ethane (DDT), used motor oil, and coal tarcontaminated soil. (22 ref.)
