The present study is an integrated approach to study the potential of Desertifilum tharense MSAK01 for treatment of dairy wastewater (DWW) and enrichment of biomass. The present research includes the experiment designed for treatment of DWW. The physical and chemical parameters of wastewater quality, such as nitrate, phosphate, chloride, sulphur, and hardness, were studied. The level of nitrate and phosphate in water bodies was reduced by 94 and 98% in the effluent, respectively. The level of BOD and COD, measure of organic contaminants, were reduced to 70% (BOD5, initial level of 1840 mg O 2 L −1 ) and 56% (COD, initial level of 2470 mg O 2 L −1 ). The second module of the experiment was designed for biochemical extractions by harvesting the biomass (algal strain) grown in DWW. The result of this study shows that algal strain D. tharense is not only an agent for mitigation of pollutant load, but it can also be used as potential source for lipid, protein and carbohydrate.
