چکیده

Single cell oil is a promising alternative feed stock in biodiesel production. Application of SCO is the subject of many studies which seek to optimize fermentation process and to reduce production cost. Utilization of plant wastes as carbon source and optimization of their physical and chemical condition can reduce the processing cost. In this study an oleaginous yeast strain, Rhodosporidium babjevae , was utilized for SCO production. The experiment design is applied in optimizing process and Qualitek-۴ (W۳۲b) software is used for analyzing the experiments. The obtained results indicate that the following levels of ۱۰.۹۷ g/L, ۱۸.۸۴ g/L and ۵۸.۲% are available as lipid, dry biomass and lipid productivity, respectively. It is revealed here that Rhodosporidium babjevae is a very appropriate candidate for SCO production and the physicochemical properties of the obtained biodiesel was confirmed according to the US and EU standards. In this case application of oleaginous yeast and mold would be an appropriate solution to prevail feed stock for biodiesel production.
