The role of microorganisms in the treatment of dye-containing wastewater using a sequential facultative anaerobic-aerobic bioreactor has received significant attention due to its ability to not only decolorize the wastewater but also to detoxify the effect of aromatic amine accumulation [1; 2].
While the biological processes provide a low-cost, environmentally benign, and efficient alternative for the treatment of dye wastewater, wany species of bacteria, fungi, yeasts, microorganisms and algae are able to decolorize various kinds of textile dyes under certain environmental conditions.
Fungi have attracted much attention because of their ability to decolorize dyes compared to simple single cell organisms as their increased cell-to-surface ratio provides a greater physical and enzymatic contact condition [3].
Many microorganisms belonging to the different taxonomic groups of bacteria, fungi, actinomycetes, and algae have been reported for their ability to decolorize azo dyes [12].
