From: Calcium-chelating alizarin and other anthraquinones inhibit biofilm formation and the hemolytic activity of Staphylococcus aureus

Figure 4

The effect of Ca2+ and alizarin on biofilm formation by S. aureus.

Structures of the alizarin/calcium/aluminum complex (a)26. Biofilm formation by MSSA 6538 was quantified in M9 minimal medium supplemented with Ca2+ (b). EGTA (a calcium-specific chelator) complements the effect of calcium and decreases the effect of alizarin (c). At least two independent experiments were conducted (6 wells for each sample). Error bars indicate standard deviations. *P < 0.05 for the indicated pairs of groups.
