Fenthion was metabolised by the white-rot fungus Phanerochaete chrysosporium in liquid culture when applied to the limit of its solubility in aqueous media (7.2 μM). Using GCNPD, no evidence for either adsorption to or accumulation in intra-cellular compartments was obtained and after 5 days culture, less than 1% of fenthion remained in the extracellular medium. Fenthion did not inhibit spore g...
