Cyanobacteria have gained interest in recent decades as intriguing potential bioresources candidates due to their potential applications in biotechnology. Under heterotrophic circumstances, the decolorization of Dianix Blue CC, Benazol Black Zn, and Dianix Yellow Brown CC by the low-cost biosorbent Phormidium (Cyanobacteria) with three different initial dye concentrations of 25, 50, and 100 mg/L was examined. For the best dye decolorization, the carbon source, incubation period, temperature, pH, and agitation rate were 10 g/L glucose, 168 h, 40 0C, 8.5, and 60 rpm, respectively. Phormidium showed high dye uptake, with maximum efficiency ranging from 20% to 40% (5.47 to 40.04 mgg-1) for Dianix Blue, 22% to 52% (5.95 to-52.32 mgg-1) for Benazol Black ZN and 20% to 68% (13.18 to 20.78 mgg-1) for Dianix Yellow Brown under heterotrophic conditions at all dye concentrations tested. The best color decolorization in terms of maximum efficiency was obtained 57% (57.76 mgg-1) for Dianix Blue, 74% (74.04 mgg-1) for Benazol Black at 100 mg/L and 77% (19.42 mgg-1) for Dianix Yellow Brown at 25 mg/L dye concentrations. The study reveals that the decolorization of dye process using Phormidium offers an efficient, quit of charges and environmentally friendly biosorbent for the remediation of textile effluents.
