Several methods have already been used to treat textile dyes present in effluent including physico-chemical methods but they are expensive and involve the formation of concentrated sludge that creates a secondary disposal problem. In recent years, as an alternative to physico-chemical methods, biological methods (using bacteria, fungi, algae and plants and their enzymes) have received increasing interest for decolorization and degradation of dyes present in effluents due to their cost effectiveness and eco-friendly nature. The ability of microorganism and plant derived enzymes to decolorize and degrade the dyes has long been known and has proved to be the most effective molecular weapon for bioremediation.
