Dyes are a major source of contamination in industrial wastewater, posing significant challenges for effective remediation due to their structural resilience, low biodegradability, recalcitrant behavior, and toxic properties. Given the limitations conventional treatment methods, recent research has increasingly focused on developing innovative, sustainable, environmentally friendly solutions address this pressing issue. This study investigates potential Pseudomonas aeruginosa biological by comparing two textile dyes: anionic indigo carmine (IC) cationic safranine-T (ST). The influence different initial dye concentrations (50, 100, 150, 500 mg L-1), agitation rates (static vs 125 rpm), growth medium (25 50 g L-1) was also assessed. It found that P. achieved >96% decolorization IC within 8 h under agitation, with rate 60.27 L-1 h-1. In contrast, ST showed limited removal (77.2%) only lowest concentration highest concentration. Agitation consistently enhanced removal, likely metabolized as an energy source, while attributed biosorption. Second-order kinetic models best described process. These findings highlight resources efficient, sustainable wastewater treatment, offering viable alternative methods contributing environmental sustainability. Further optimization process conditions could broaden its application effluent management.
