Additional information on results:
No precitation of the test sub stance was found.

Occasionally, a slight decrease in the number of revertants was observed in the standard plate test with S-9 mix at 5,000 ug/ plate . In the preincubation assay bacteriotoxicity was found depending on the strain and test conditions_at doses > 2,500 ug / plate
