[Role of coryneform bacteria in the degradation of ordram in a reservoir].
The object of the work was to study the role of coryneform microorganisms in the degradation of residues of ordram, a thiocarbamate herbicide. Only rhodococci were found to play an essential role in the process among these bacteria. Rhodococci actively oxidized the herbicide if its concentration was several milligrams per litre though its high concentrations (over 100 mg/l) inhibited the growth of the bacteria. This group of microorganisms, together with bacilli and certain cocci, belongs to the most active part of saprophytic microflora which transforms the molecule of the original herbicide yielding keto and hydroxy derivatives, sulfoxide, products of S-dealkylation and cleavage of the hexamethyleneimine ring. The incidence of rhodococci remains at a high level if the appropriate cosubstrates are added. In the conditions of rice check plots, rhodococci can play an essential role in the degradation of the herbicide.
