Abstract
Biotransformation of atrazine by the white rot fungus Phanerochaete ch rysosporium was demonstrated by a 48% decrease of the initial herbicid e concentration in the growth medium within the first 4 days of incuba tion, which corresponded to the mycelium-growing phase. Results clearl y 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.
