Anthraquinone Dye

RBBR is a typical anthraquinone dye used in the textile industry, represents an important class of toxic and recalcitrant organopollutants. It was reported that the dye can be decolorized by many white-rot fungi and Myrothecium sp. IMER1. Therefore we compared decolorization capability of Myrothecium sp. IMER1 for Remazol Brilliant Blue R (RBBR) with five different whiterot fungi over a pH range of 5.0 to 10.0. Anthraquinone core. These compounds impart color to plants and have been widely utilized as natural dyes. In addition, they are also used as laxatives and possess antifungal and antiviral activities. Laxative anthraquinones include physcion, chrysophanol, aloe-emodin, rhein, and sennosides. Anthraquinone dyes are an abundant group of dyes comprising a anthraquinone unit as the shared structural element. Anthraquinone itself is colourless, but red to blue dyes are obtained by introducing electron donor groups such as hydroxy or amino groups in the 1-, 4-, 5- or 8-position.
