With the increasing use of synthetic dyes in textile industries, there has been a simultaneous increase in the levels of water pollution, as a result of release of effluents from these textile industries. The effluents constitute majorly of synthetic dyes which are toxic and harm aquatic organisms. Thus, we need to treat the effluents prior to release into the environment. The available physio-chemical methods have limitations when applied at large scale, and thus biological methods are the most suitable. Biological agents may be biomass or purified enzymes. Dye decolorization is achieved mostly by either/both biodegradation and biosorption. In biodegradation, the dye is converted to a less toxic product by microbial enzymes, and in biosorption the dye particles are adsorbed on the surface of the microbial cells. In this review, there is a compilation of the efficiency of dye decolorization by enzymatic degradation of various azo and anthraquinone dyes by microbial enzymes. |
