摘要
以在海南分离的藻株小球藻HNC1(Chlorella sp.HNC1)和微拟球藻HNN1(Nannochloropsis sp.HNN1)为材料,研究N和Fe3+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Fe3+的缺乏抑制了小球藻的生长和油脂的积累;Fe3+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Fe3+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Fe3+和正常铁条件下小球藻和微拟球藻的生长无显著差异.
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＋.
