Abstract: Dwindling water resources is a global problem. Effective effluent treatment is an important step towards conserving our water resources. Some pollutants such as dyestuffs resist degradation by conventional treatment methods and persist in the environment. The paper describes the use of enzymes as an alternative method for treatment of such recalcitrant pollutants. It evaluates different methods in which enzymes can be delivered to the target effluent, including nanoparticles as delivery systems. It also emphasizes the need for current and future research to focus on developing economically feasible and environmentally sustainable wastewater treatment practices. An acid-producing filamentous fungus, Aspergillus Niger NB2, used throughout this study, was maintained on potato-dextrose agar slants and Yeast malt agar. This new glucose method offers an efficient process that preserves these sensitive molecules and is a step-change in analysis of madder dyed textiles as it can provide further information about dye preparation and dyeing processes that Current methods cannot. Dye is an integral part which is used to impart colour to materials. The waste generated during the process and operation of the dyes, contains the inorganic and organic contaminant leading to the hazard to ecosystem and biodiversity causing impact on the environment. The physico-chemical treatment does not remove the color and dye compound concentration. The decolorization of the dye takes place either by adsorption on the microbial biomass or and enzymatic degradation. Bioremediation takes place by anaerobic and/or aerobic process. In the present review the decolorization and degradation of dyes by fungi, algae, yeast and bacteria have been cited.
