Biotransformation of the herbicide atrazine by the white rot fungus Phanerochaete chrysosporium

Biotransformation of atrazine by the white rot fungus Phanerochaete chrysosporium was demonstrated by a 48% decrease of the initial herbicide concentration in the growth medium within the first 4 days of incubation, which corresponded to the mycelium-growing phase. Results clearly established the mi...

Description
Summary:Biotransformation of atrazine by the white rot fungus Phanerochaete chrysosporium was demonstrated by a 48% decrease of the initial herbicide concentration in the growth medium within the first 4 days of incubation, which corresponded to the mycelium-growing phase. Results clearly established the mineralization of the ethyl group of the herbicide. Analysis of the growth medium showed the formation of hydroxylated and/or N-dealkylated metabolites of atrazine during fungal degradation
