Biological degradation of isoproturon, chlortoluron and fenitrothion.

For the purpose of biodegradation studies several microorganisms were isolated from soil and adapted under laboratory conditions in the presence of pesticides, with the following degradation results: isoproturon after 72 h-86%, chlortoluron after 72 h-93%, after 65 h-88% and fenitrothion after 72 h-66%. The cultures can be used for the biodegradation of pesticides in the lyophilized state with or without an organic carrier.
