Autochthonous (indigenous) microorganisms present in polluted environments hold the key to solving most of the challenges associated with biodegradation and bioremediation of polluting substances (Verma and Jaiswal 2016) provided that environmental conditions are suitable for their growth and metabolism. In addition to the usage of all cell microorganisms, the use of their enzymes extracellular and/or cell-free is suggested as a creative emission control strategy. Though organic pollutants may not be a direct source of carbon supply for microalgae but the air which is supplied inside the reactor for mixing would initiate the oxidation process of organic compounds along with photo-biodegradation (Ting et al., 2017). This can be accomplished by the use of chemical, physical or biological entities, such as microorganisms, fungi and green plants, through the enzymes that they produce. ions, polynucleotides, etc. The effects in, Methyl violet, a basic dye, is manufactured using phenol and dimethylaniline as the raw materials.
