摘要：

As pan of a study conducted on the fate of xenobiotics in the environment, a selection of 100 strains of micromycetes (Ascomycetes, Basidiomycetes and Yeasts) have been cultivated in liquid synthetic medium with 3 phenylurea herbicides :chlortoluron and isoproturon(100mg L-1) and diuron (20mg L-1). While 17 strains depleted isoproturon over 50 % only 4 depleted diuron and 2 chlortoluron at the same level. The best results were obtained with Bjerkandera adusta and Oxysporus sp which were the most efficient towards the 3 substrates. After 2 weeks Bjerkandera adusta depleted chlortoluron 98%, diuron 92% and isoproturon 88%. (C) 1999 Elsevier Science Ltd. All rights reserved.
