Wastewater released from textile industries causes a large burden to put environment on risk due to its low biodegradability and harmful quality. Due to complexity in their chemical structure, synthetic dyes are extremely difficult to be present for degradation. Therefore, the dye wastewaters are highly toxic to crop plants, both aquatic fauna and flora including human beings. Couple of strategies such as physico-engineered systems are used to treat textile effluent. Unfortunately, these methods are found to be intemperate due to delivering hazardous by-products. Biological decolorization is an economically viable method and environment friendly thus presents a good alternative to engineered process. Many organisms (bacteria, fungi and algae) have good shown good adsorption of dyes and degrade dyes as they possess several important dye degrading enzymes. Microbial processes are found to be potent for the mineralization of synthetic dyes. Nevertheless, real potential of the microbial strains and their enzyme could be tested in suitable bioreactors for its future application in treatment of textile effluent.
