Oleaginous yeast has become some of the most promising feedstock for biodiesel production due to their high production efficiency [1]. However, high cost of cultivation, especially substrate cost, hinders rapid commercialization of yeast-based biodiesel [2]. In this study, microalgae (Chlorella), which is rich in nutrients and organic matters, was examined as an economic substitute for organic substances [3], and Cryptococcus curvatus, which was isolated from a fermented seafood, was used for biodiesel production. To be efficiently bioavailable, microalgae must be pretreated. Hydrodynamic cavitation reaction time and pH were identified as experimental factors, whereas growth rate was selected as response parameter. The experimental factors were optimized employing Response Surface Methodology (RSM). Growth rate of 0.605 /h was optimized at reaction time 6.88 min and pH 9.47. When Chlorella supernatant pretreated under these optimal conditions was used as a complete nutrient, 7.47. g of biomass was obtained in three days and lipid was accumulated up to 27% of dry weight.
