Any other information on results incl. tables
No bacteriotoxic effects up to 158 µg/plate; total bacterial count remained unchanged an no growth inhibition was seen.
At doses above 158 µg/plate strain-specific cytotoxicity.
Compound precipitation started at 500 µg/plate; and 5000 µg/plate could not be used for evaluation.
