Biodiesel is an attractive alternative fuel for diesel engines due to its technical, environmental and strategic advantages.The viability of production of Biodiesel from microalgae grown in waste water co-produced with crude oil and natural gas (termed as produced water), was studied in the present analysis. In the present work the growth patterns of the Freshwater oleaginous microalgae Scenedesmus obliquusin two different growth conditions i.e. one experimental set grown in only BG11 culture media and other in BG11 culture media coupled with Produced water (PW) were studied for a period of 30 days. Studies were also conducted on different extraction solvents used for lipid and transesterification process. The maximum yield biodiesel of S. obliquus grown in BG11 Media was found out to be 35.45 % and in 40% PW+ BG11 media biodiesel obtained using hexane in a single stage transesterification process was 48.32%.Gas chromatographic analysis data also showed that biodiesel derived from S. obliquus grown in 40% FW is richly composed of Oleic acid and linoleic acid methyl ester. Fuel properties showed that biodiesel were comparable in quality with that of other conventional biodiesel.
