Efficient biodegradation and detoxification of reactive black 5 using a newly constructed bacterial consortium.

ABSTRACT: The release of azo dyes into wastewater from textile industries poses a significant environmental challenge due to their toxicity and recalcitrance. Among these dyes, Reactive Black 5 (RB5) is one of the most widely used and environmentally persistent due to its complex aromatic structure, high stability, and extensive use in the textile sector. This study aimed to develop and optimize a highly efficient bacterial consortium for the decolorization and detoxification of RB5. Three bacterial species-Bacillus cereus, Proteus mirabilis, and Stenotrophomonas maltophilia-were isolated from industrial effluents and combined into a consortium based on compatibility testing. The optimization of cultural and incubation conditions using Plackett-Burman Design (PBD) and Central Composite Design (CCD)
