The humongous load on the environment due to the expulsion of textile dye wastewater has always been a major issue. Significantly, the dye is present in the wastewater due to its complex chemical structure, making it a recalcitrant pollutant. Therefore, becoming highly noxious to flora and fauna of the aquatic ecosystems and crop plants. Due to the low biodegradability, dyes are carcinogenic and mutagenic to plants and human beings. Various physicochemical strategies to treat textile effluent have been used, but because of several drawbacks, they are not implemented by most industries. Microbial decolorization is more eco-compatible and economical as it does not produce any intermediate by-products. Also, it can mineralize the dyes completely and efficiently. Microbes like bacteria, fungi, and algae possess enzymes capable of degrading dyes. These organisms are now in trend with the utilization of mixed culture in comparison to the use of individual strain. Bioremediation of pollutants reduces the toxicity from the soil and water source so that water used for irrigation will no longer be harmful to the plants and eventually to us. Keywords: Textile, effluent, bioremediation, decolourization, pollutants
