Resumo
The optimization of the anaerobic degradation of the azo dye Remazol golden yellow RNL was performed according to multivariate experimental designs: a 22 full-factorial design and a central composite design (CCD). The CCD revealed that the best incubation conditions (90% color removal) for the degradation of the azo dye (50 mg L–1) were achieved with 350 mg L–1 of yeast extract and 45 mL of anaerobic supernatant (free cell extract) produced from the incubation of 650 mg L–1 of anaerobic microorganisms and 250 mg L–1 of glucose. A first-order kinetics model best fit the experimental data (k = 0.0837 h–1, R2 = 0.9263).
