8. Microbial degradation of textile industry effluents: A review

Abstract

During textile processing, different waste materials are produced at different stages including dyes and wastewater. These chemicals and wastewater are ultimately released into environment that negatively affects its biota because of detrimental changes brought into the surrounding by these unused and untreated materials. The major problems being imposed by textile industry include: excessive usage of water, control of its frequent discharge into environment and treatment of this effluent loaded waste water. Industries are struggling to find out some novel solutions for treatment of these wastes to diminish the environmental damage being caused by effluent discharge. In recent years, there is an increasing trend of using different kinds of microorganisms for degradation purpose of textile industries effluents. Because of low cost and long lasting effect of biological remediation of industrial wastes, there has been an increasing demand for new and novel biological solutions for industrial effluent management. In this context, this review summarize major textile dyes, different bioremediation ways by which textile dye effluents can be treated and microbes capable of degradation and decolorization that can be applied in order to develop cost effective methods for textile effluents treatment.
