Owing to their industrial applications, many synthetic dyes are commonly present in wastewater and cause serious pollution of the aquatic environment. Most synthetic dyes are toxic, mutagenic, and carcinogenic. No universal method is available for the treatment of dye-contaminated wastewater because of the complex and varied chemical structures of these dyes. Of the current methods used for treating wastewater, microbial methods offer considerable advantages such as high efficiency, are environment friendly, and involve low operation costs. This review presents the latest research on microbial decolourisation of synthetic dye. Mechanisms involved in the bioremoval of dyes, pathways underlying the biodegradation of most important dye classes, and physicochemical parameters affecting dye decolourisation have been summarised in this review. In addition, this review discusses genetic manipulation of microorganisms and enzymes used for dye decolourisation read more ...
