【 摘 要 】

Human body has limited ability to synthesize unsaturated fatty acids such as AA, DHA, EPA. These fatty acids are essential for the body. This study initiated the efforts to produce unsaturated fatty acids of microorganisms, with low cost and high percentage. This study used tapioca and tofu waste as a medium for Aspergillus. In addition, this study analyzed the varying of carbon concentration to the maximum lipid production from Aspergillus oryzae and determine the optimum rate of agitation against lipid production from Aspergillus oryzae. The results shows that the optimum composition of AA, DHA, EPA are 0.18% (w / w), 0.33% (w / w), and 2.96% (w/w) respectively in concentration carbon of 9% (w/w) and agitation rate of 120 RPM.
