| 中文摘要 | Lipid production is an important indicator for assessing microalgal species for biodiesel production. In this work, the effects of medium composition on lipid production by Scenedesmus sp. were investigated using the response surface methodology. The results of a Plackett-Burman design experiment revealed that NaHCO3, NaH2PO4 center dot 2H(2)O and NaNO3 were three factors significantly influencing lipid production, which were further optimized by a Box-Behnken design. The optimal medium was found to contain 3.07 g L-1 NaHCO3, 15.49 mg L-1 NaH2PO4 center dot 2H(2)O and 803.21 mg L-1 NaNO3. Using the optimal conditions previously determined, the lipid production (304.02 mg center dot L-1) increased 54.64% more than that using the initial medium, which agreed well with the predicted value 309.50 mg L-1. Additionally, lipid analysis found that palmitic acid (C16:0) and oleic acid (C18:1) dominantly constituted the algal fatty acids (about 60% of the total fatty acids) and a much higher content of neutral lipid accounted for 82.32% of total lipids, which strongly proved that Scenedesmus sp. is a very promising feedstock for biodiesel production. |
