| 摘 要： | 以在海南分离的藻株小球藻HNCl（Chlorellasp.HNC1）和微拟球藻HNN1（Nanno-chloropsisSp.F1NNl）为材料，研究N和Fe^3＋对细胞油脂积累的影响。结果表明：N缺乏条件促进了小球藻和微拟球藻细胞的油脂积累，但对生长有抑制作用。与对照相比，培养基中Fe^3＋的缺乏抑制了小球藻的生长和油脂的积累；Fe^3＋缺乏对微拟球藻的油脂积累有抑制作用；但对其生长无明显影响。富Fen处理对小球藻的油脂积累具有刺激作用，但对微拟球藻无显著影响；富Fe^3＋和正常铁条件下小球藻和微拟球藻的生长无显著差异。

| Abstract: | Taking the algae Chlorella HNC 1 （Chlorella sp. HNC1） and micro-algae HNN1 （Nannoehloropsis sp. HNN1 ） separated in Hainan as the research material, the effect of N and Fe^3＋ on the cell lipid accumulation was stu- diced. The results show that： Lack of N can promote the cell lipid accumulation of the chlorella and micro-algae, but the growth was inhibited. Compared with the control, lack ofFe^3＋ in the medium inhibited the growth of Chlorella and oil accumulation;lack of Fe^3＋ inhibited the lipid accumulation of micro-algae, but had no effect on their growth, Rich Fe^3＋ can stimulate the lipid accumulation of ehlorella, oil, but has no effect on the micro-algae; There was no significant difference for chlorella and micro algae in the condition of rich or mormal Fe^3＋. |
