Textile wastewaters generate by the textile industry contain numerous dyes which are highly toxic and a serious threat for the whole environment. Some of these dyes are highly persistent and if carried by humans, it causes serious health issues including cause bladdercancer, skin dermatoses, allergic responses, eczema, and have adverse effects on the lungs, liver, circulatory, reproductive, and immune system. Although various methods have been proposed for remediation of textile wastewaters, but they are not efficiently address the problem either due to their cost or their less effectiveness against various dyes simultaneously. Some of the physical methods like use of adsorbents seems to be less effective as in this way although dyes are absorbed but still present in the environment and may cause serious threat if release back into the environment.

Pakistan is the eighth largest exporter of textile commodities in Asia and earn 8.5 % of GDP from textile industry. Wastewater generated by these industries is mostly introduce into the water bodies without any treatment which cause serious threat for the whole environment. It is required to develop technology from indigenous resources that is cheap and efficient to treat textile wastewaters. In the present study, the main objective is to isolate various species that have potential to detoxify dyes specially the azo dyes and design a bioreactor based on these microbial species that efficiently treat the textile wastewater. Various approaches can be use here to detoxify the dyes containing water where microbes will be applying as free as well as immobilized form (which can be use many times and cost effective), biofilms of microbial species will also be applied for the treatment and their crude enzymes will also be use for efficient degradation of azo dyes.
