Biotransformation of 1-Hydroxychlordene by White Rot Fungus and Detection of Metabolites

Article Preview

Abstract:

l-Hydroxychlordene is the major metabolite of organochlorine pesticide heptachlor in soil. In this study, the biotransformation of l-hydroxychlordene was performed with the white rot fungus Phlebia acanthocystis TMIC34875, which is capable of degrading heptachlor. As a result, 1-hydroxychlordene was degraded completely by the fungal treatment in pure cultures after 15 days of incubation. A large amount of epoxylation product1-hydroxy-2,3-epoxychlordene was detected as metabolites of 1-hydroxychlordene using GC/MS analysis. This fungus particularly can degrade 1-hydroxy-2,3-epoxychlordene to two trihydroxychlordene isomers through hydrolysis at epoxy ring. The results suggested that 1-hydroxychlordene was metabolized to hydrophilic products via 1-hydroxy-2,3-epoxychlordene by P. acanthocystis TMIC34875.
