Dye is a compound that is either natural or synthetic derivative used to impart colour. Dyes are effectively used in several industrial sectors, such as textile, cosmetics, food industry, etc. owing to their attraction towards the consumers and their ease to use the product. The increased utilisation of these dyes directly affects the environment in many ways. The synthetic dyes containing effluents are one of the challenging tasks in sewage treatment. The treatment used for the dye removal through microbial method is more convenient, eco-friendly and cost-effective than any conventional method. Dye removal using micro-organisms handles different methods, including biodegradation of dye compound into various byproducts with the help of active enzymes produced by the microbes. On the other hand, dye removal is also being performed through biosorption methodology in which binding of dye compounds to the biomass and removal of the same is achieved. Either live or dead biomass is utilised for the latter process and is found to be an efficient time-bound method than the former one. Although bacteria and fungi are involved in the latter process, comparatively, yeast is found to be inexpensive, non-toxic and far better for the biosorption process since large biomass of yeast can be produced using cheaper carbon and nitrogen sources. Our research with Saccharomyces cerevisiae is evolving day-by-day and currently our research team is involved in involving the most studied eukaryotic microbe in ecoremediation process. Our research team is happy with the first phase results of the research.
