Effects of alizarin-related compounds on cell aggregation.
S. aureus MSSA 6538 cells were grown for 20 h in the presence of alizarin-related compounds (10 μg/ml) (a) or in the presence of alizarin (0, 2, 5, or 10 μg/ml) (b). Absorbances of the top 1 ml portions of test tubes were measured at OD600. Tested tubes are shown. At least two independent experiments were conducted. *P < 0.05 versus non-treated controls (N or 0).
