The type and amount of lipid produced by microalgae directly influence the quality of the achived biodiesel. This study is to report the properties of extracted lipid profile analysis of marine microalgae species Chlorella sp. The extracted lipid is further converted to methyl esters or biodiesel by acid-catalyzed transesterification. Scanning electron microscope (SEM), Gas chromatography (GC) and Fourier Transform Infrared spectroscopy (FT-IR) are analytical instruments for evaluation the potential of microalgae lipid in biodiesel production. The result showed that our marine microalgae was confirmed as interesting candidate for biodiesel application due to its high lipid content, high biodiesel yield, high cetane (CN) number, low iodine value (IV) and FT-IR spectrum close to crude palm oil and crude palm oil biodiesel.
