The lipid content of microalgae is important for biodiesel production. In this study, we determined photosynthetic performance, biomass composition and lipid production of marine unicellular microalgae Chaetoceros muelleri (Bacillariophyceae) and Dunaliella salina (Chlorophyceae) cultured under different nutrient deprivation conditions. The results showed the highest lipid content of C. muelleri (46.32±3.53%) and D. salina (54.15±2.71%) could be achieved by nitrogen and complete nutrient deprivation, respectively. Analysis of fatty acid methyl esters (FAMEs) profile under those conditions revealed that the lipid accumulated by the two species was suitable to produce biodiesel. From these studies, we concluded that C. muelleri and D. salina would be highly suitable candidates for biodiesel production.
微藻的脂质含量对于生物柴油的生产很重要。在这项研究中,我们测定了在不同营养剥夺条件下培养的海洋单细胞微藻角毛藻(硅藻门)和盐生杜氏藻(绿藻门)的光合性能、生物量组成和脂质生产。结果表明,角毛藻(46.32±3.53%)和盐生杜氏藻(54.15±2.71%)的最高脂质含量可以通过氮和完全营养剥夺来实现。在这些条件下分析脂肪酸甲酯(FAMEs)的图谱表明,两种生物积累的脂质适合生产生物柴油。从这些研究中,我们得出结论,角毛藻和盐生杜氏藻将是生物柴油生产的高度合适的候选物。
