In this work, the bioremediation of wastewater from textile industry with indigo dye content was carried out using combined bioaugmentation, bioventilation, and biostimulation techniques. Initially, inoculum prepared by isolating microorganisms in a 2 L bioreactor. Then, respirometry technique implemented to determine affinity substrate measuring CO2 allowed formulation an empirical mathematical model for growth kinetics microorganism. Finally, 3 bioreactor obtaining removal efficiency 20.7 ± 1.2%, 24.0 1.5%, 29.7 1.1% equivalent wavelengths 436 nm, 525 620 nm. The chemical oxygen demand showed average reduction 88.9 2.5%, going 470.7 15.6 52.3 10.7 ppm after 30 days under constant agitation aeration. A negative generalized exponential fitted assess microorganism as evaluating production during bioremediation. Bioremediation techniques improve water discharge parameters compared treatments industry, reducing use substances that can generate secondary pollution. Bioaugmentation, biostimulation, bioventing study demonstrate potential these serve efficient alternative indigo-contaminated industry.

The textile industry produces high volumes of colored effluents that require multiple treatments to remove non-adsorbed dyes, which could be recalcitrant due their complex chemical structure. Most the studies have dealt with biodegradation mono or diazo dyes but rarely poly-azo dyes. Therefore, aim this paper was study a four azo-bond dye (Sirius grey) and optimize its decolorization conditions. Laccase-containing cell-free supernatant from culture newly isolated fungal strain, Coriolopsis gallica strain BS9 used in presence 1-hydroxybenzotriazol (HBT) A Box–Benken design factors, namely pH, enzyme concentration, HBT performed determine optimal conditions for Sirius grey. were pH 5, 1 U/mL laccase, mM HBT, 50 mg/L initial ensuring yield rate 87.56% 2.95%/min, respectively. decolorized solution showed decrease phytotoxicity (Germination index GI = 80%) compared non-treated (GI 29%). This suggests laccase-mediator system promising alternative removal wastewater.
