Abstract:
We investigated the degradation pathways and kinetics of 2,4-dichlorophenol (DCP) by an endemic soil fungus, Mortierella sp. (Zygomycetes). Mortierella sp. degraded 32% of added DCP (final concentration, 250 microM) within 1 h. We identified four aromatic metabolites and found two DCP degradation pathways (a hydroxylation pathway and a dechlorination pathway). This is the first report of a dechlorination pathway in Zygomycetes.
