摘要: 通过柱式光生物反应器培养,比较研究三株栅藻(Scenedesmus sp简写S. sp、Scenedesmus deserticolaScenedesmus dimorphus)的生长及油脂含量情况,得出3株藻生物量最高的是S. deserticola 为0.48 g/(L·d);其次是S. sp为0.41 g/(L·d);S. dimorphus产量最低为0.35 g/(L·d)。且培养后期经尼罗红染色清楚可见油脂分布,其中S. deserticola总脂含量达到了干重的55.3 %,总脂产量为0.29 g/(L·d);S. dimorphus为46.7 %,0.18 g/(L·d);S. sp为43.6 %,0.20 g/(L·d)。三株栅藻主要脂肪酸为C18和C16,占总脂肪酸组成的85 %以上,符合生物柴油的生产要求。综合比较,S. deserticola是一株性能优良的产油藻株。

Abstract: The growth and the lipid content of 3 strains of Scenedesmus were compared by column photobioreactor,and it was concluded that the strain of producing the highest biomass was Scenedesmus deserticola with 0.48 g/(L·d),followed by Scenedesmus sp(S. sp)0.41 g/(L·d),and the lowest by S. dimorphus with 0.35 g/(L·d). In the late culture stage,the lipid distribution was clearly visible by Nile red staining. The total lipid content and the lipid productivity of S. deserticola were 55.3 % of DCW and 0.29 g/(L·d),respectively,followed by S. dimorphus in 46.7 % and 0.18 g/(L·d),S. sp in 43.6 % and 0.20 g/(L·d). The main fatty acid composition of 3 Scenedesmus were C18 and C16,accounting for over 85% of total fatty acids,satisfying the requirements of biodiesel production. Comprehensive comparison revealed that the S. deserticola was a lipid-producing strain with high performance.
