The pH is adjusted to 6. For example, Reactive Blue RB also known as Remazol brilliant blue anthrasuinone an anthraquinone based vinylsulphone dye, which is very resistant to chemical oxidation due to its anthraquinone structure being stabilized by resonance [6]. The anthraquinone is a redox catalyst. The anthraquinones rubiadin and its 1-methyl ether isolated from Heterophyllaea pustulata reduces Candida tropicalis biofilms antnraquinone.
