Reactive Brilliant Blue (KN-R) is an anthraquinone-type dye, which has a wide-ranging application and a high output. The wastewater from manufacturing and processing operations is imbued with high-color, big-toxicity and poor biodegradation. As a result, decolorization of Reactive Brilliant Blue (KN-R) is essential. In this paper it is found for the first time that, through the separating and sorting of microorganizism, a strain Rhodocyclus gelatinosus is capable of decolorizing Reactive Brillian...
