Chemical and oil industries generate a large sort of extremely cyanogenetic organic pollutants, that have led to additive venturous effects on the atmosphere. The waste material comes out from chemical industries usually contain aromatic organic compounds that are not degraded naturally and so continue in the atmosphere. This makes these hazardous compounds for bioaccumulation in human and tissue. Organic pollutants represent a possible cluster of chemicals that may be seriously venturous to human health. Biological strategies for treatment of effluent containing organic micro pollutants are getting a lot of accepted over the globe. This review concentrate on the pathway for the biodegradation of benzene, toluene, ethylbenzene and xylenes (BTEX) underneath model conditions by microalgae and to grasp the anaerobic and anaerobic biodegradation pathways for BTEX compounds. These results favor the biomass when biodegradation method and create it enticing for additional use as an acceptable substrate for resultant processing into biofuels of third generation.
