Abstract
Scenedesmus obliquus was discussed by phycologists as a promising microalga for biodieselproduction based on its biomass and fatty acid productivity. In the present study, S. obliquuswas pilot cultivated for large scale production in a semi continuous culture for three months usingbubbled glass boxes photo- bioreactor. Cultivation of S. obliquus resulted in a maximum biomassproductivity of 0. 59 g L−1 d−1 and maximum esterified fatty acid productivity of 20.37 mg l−1 d−1in (March, April and May), different flocculants for biomass harvest showed maximumflocculation efficiency of 82% using 250 mg l−1 of NaOH for 2 h. Solar drying of the harvestedbiomass showed significant increase of esterified fatty acid content by 50% with respect to control.In addition, fatty acid profile and iodine number of S. obliquus oil meet biodiesel standardspecifications which make the fatty acid of S. obliquus eligible for further research to be used as afeed stock for biodiesel production.
