One strain of ectomycorrhizal fungi, Xerocomus chrysenteron, had been investigated for its ability to degrade 1,1,1-trichloro-2,2-bis(4-chlorophe-nyl) ethane (DDT) by measuring unlabeled DDT and identifying its metabolites, and determining the mineralization of [(13)C]DDT in pure cultures. After 45d incubation, about 55%

Four compounds--2,2', 3,4'-tetrachlorobiphenyl, decachlorodiphenylether, 1,1-dichloro-2,2-bis(p-ethylphenyl)ethane, and dichlorobenzophenone--are recommended for monitoring the within-sample behavior of an analytical method that quantifies chlorinated pesticides and polychlorinated biphenyls (such as Aroclor 1260) in serum using packed column gas chromatography with electron capture detection.

Extensive biodegradation of 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT) by the white rot fungus Phanerochaete chrysosporium was demonstrated by disappearance and mineralization of [14C]DDT in nutrient nitrogen-deficient cultures. Mass balance studies demonstrated the formation of polar and water-soluble metabolites during degradation. Hexane-extractable metabolites identified
