ترجمة الملخص

The possibility of biodiesel production from lipids extracted from local microalgal species cultivated in municipal wastewater was studied, due to the increasing in the importance of finding renewable energy sources especially biofuel, Different microalgae species were isolated, C.vulgaris and S. obliquus were chosen to be cultivated for biomass optaining, lipids extraction and biofuel production. Studied species were grown in various growth media (natural and artificial) to compare biomass productivity. Different methods of lipid extraction (Folch, Hara & Radin, Bligh & Dyer) using organic solvents, and four cell disruption methods (ultrasonication, microwave, autoclaving) for lipid yield increasing, were investigated. The efficiency of removing pollutants (nitrate, phosphate, COD from wastewater ) by the studied species was determined, fatty acids content in biodiesel were studied using GC-MS, after it was esterified with Alkaline and acid esterification. Biomass productivity was 0.1 g /l/day in C. vulgaris and 0.09 g /l/day in S. obliquus in wastewater medium, and it was the highest comparing with other medium. Extraction with Folch method gave the highest lipid yield (4.8% in C.vulgaris,3.1% in S. obliquus). Cell disruption increased the percentage of lipids where autoclaving was the most effective method (7.2 in C. vulgaris, 5.7 in S. obliquus). The main Fatty acids that comprises biodiesel were Palmitic (C16:0) and stearic (C18:0) in both species. Pollutants removal efficiency from wastewater was 73, 73, 87 % in S. obliquus and 66, 53, 75 % in C. vulgaris for COD, nitrate and phosphate Sequentially.
