Abstract

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.)
