Abstract
In this work, we have presented the results of biodegradation studies of some
pesticids by actinomycets which catched from the active sludges of airing tank of
epurating station of used water-khenchela(Baghey).Olso,we have isolated 6 samples
of actinomycets begening from two selectifs mileu Olson and GLM.The use of
nystatin like an antifongic and polymixin like antibacterian and the deffirent
conditions of isolaton were olso studied.The samples selected of actinomycets were
able to dissiciate the following pesticids :methomyl ,ortivaand glyphosat,where
cypermethrin was not dissociated by all the samples isolated
