Abstract
In this study, the concentrations of MgSO4, salinity and light intensity were optimised for maximum biomass productivity and lipid content in Chlorella sp. Lipid synthesized at varied experimental condi- tions was also assessed in detail for biodiesel properties through FAME analysis. FAMEs mainly composed of C16:0, C16:1(9), C16:3(7, 10, 13), C18:0, C18:1(11), C18:2(9, 12), C18:3(9, 12, 15). The optimum bio- mass productivity (372.50 mg L�1 d�1) and lipid content (32.57%) was obtained at MgSO4-150 ppm; salinity-12.5 ppm, and light intensity-25 lmol m�2 s�1. However, at this condition the cetane number, a major biodiesel property was not complying with worldwide biodiesel standard. Therefore, further optimisations were done to check the suitability of biodiesel fuel. The optimum biomass productivity (348.47 mg L�1 d�1) and lipid content (12.43%) with suitable biodiesel fuel properties was obtained at MgSO4-50 ppm, salinity-25 ppm and light intensity-100 lmol m�2 s�1. The validation experiments confirmed the closeness of predicted and measured response values.
