Alizarin (1,2-dihydroxyanthraquinone) is a red dye wilth mild antibacterial activity. Alizarin has been found to inhibit biofilm formation by three Staphylococcus aureus strains and a Staphylococcus epidermidis strain.
|Mechanism of Action||Alizarin has moderate antibacterial activity against Staphylococcus epidermidis and Salmonella enterica.|
