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.
