%X In this study, lipid production from oleaginous yeast Rhodotorula glutinis and biodiesel production from the extracted lipid was performed. In order to determine the maximum lipid production conditions, the effect of various system parameters such as initial pH, temperature, agitation rate, different carbon and nitrogen sources has been examined in batch fermentation system. Media containing molasses and cheese whey were also tested to reduce the cost of biodiesel production. In addition, under optimum conditions, lipid was produced with a two-step fermentation system. Lipid was extracted from culture media according to the modified Bligh and Dyer method and lipids obtained were used for biodiesel production. Analysis of fatty acids and fatty acid methyl esters was carried out on the gas chromatograph-mass spectrometer. As a result of this study, maximum lipid content and biodiesel production were 29.53 ¡À 0.46% and 80.65%, respectively. It has been determined that fatty acid composition of lipids containing palmitic acid, oleic acid and stearic acid is suitable for biodiesel production
