摘要：

为了寻找适合用于开发生物质能源的优势藻株，对分离得到的藻株Hhw进行深入研究，分析其生长情况，不同碳、氮源对其总脂含量及脂肪酸成分的影响。结果表明，Hhw生长速度快、生物量高、适应性广；硝态氮、碳源的添加促进Hhw中性脂的积累，Hhw总脂含量高达干重的36.45%；Hhw脂肪酸成分较为单一，以棕榈酸、亚麻酸、EPA等9种脂肪酸为主；不同碳、氮源对其脂肪酸组成成份的影响不大，但对各组分的含量有一定影响，如铵基氮对EPA的积累有一定促进作用。综合分析认为，Hhw是一株极具开发潜力能源微藻。

Abstract:

In order to find an advantage algae strain for biomass energy, Hhw, a preponderant microalgae, which isolated by the author was researched. The effect of carbon and nitrogen sources on the lipid and fatty acid composition of Hhw was analyzed. The results showed that Hhw had numerous advantages such as wide environmental adaptability, fast growth, high biomass production. Adding NO3- or carbon sources promoted the accumulation of lipids of Hhw. Total fat content of Hhw was up to 36.45% by dry weight. The fatty acid compositions of Hhw was relatively simple, contained mainly 9 types: palmitic acid, inolenic acid, EPA, and so on. The effect of different carbon and nitrogen source to fatty acid composition was not big, but to the content of composition was relatively strong. For example, the effect of EPA to the accumulation of amino nitrogen was stimulative in a certain extent. The analysis showed that Hhw was a superior microalgae for biomass energy.
