Results of 18s rRNA sequence analysis indicated that these strains have a close relationship with <em>Chloromonas playfairii</em> and <em>Desmodesmus opoliensis</em> named as SBC 2 and SBC 3, respectively. Both the strains removed more than 92% of ammonical nitrogen and 99% of total phosphorus, whereas COD and BOD reductions were found to be more than 95%. Maximum biomass production was 1.7 and 1.2 g L<sup>-1</sup> and lipid content was 15 and 12%, respectively from SBC 2 and SBC 3 after 15 d cultivation. This study demonstrates the potential of algae based biofuel production by coupling wastewater treatment with microalgae cultivation for high lipid containing biomass production using <em>Chloromonas playfairii</em> and <em>Desmodesmus opoliensis</em>.</p><p>Int J Appl Sci Biotechnol, Vol 3(4): 699-707</p> ER -
