| 摘 要： | 通过对三角褐指藻分别大硅不足、维生素不足、氮不忠 、磷不足等不同营养盐条件下增养的对比试验。发现随氮营养盐不足加剧,ＴＰＵＦＡ含量大幅度下降,由对照组４２．１３％降至２９．８６％（５０％Ｎ）和２０．１７％（５％Ｎ）,ＥＰＡ含量则由对照组２１．４１％降至１２．９４％（５０Ｎ）和１０．５４％（５％Ｎ）。磷不足能导至ＴＦＡ的增加和积累,但ＴＰＵＦＡ（包括ＥＰＡ）占总脂肪酸的百分比却呈现下降趋势。硅不足和

| Abstract: | The variations in the fatty acids contents and compositin in P.tricornutum were studied under nutrient (Si, Vitamine, N and P) starved culture conditions. In N starveling experiments, TPUFA contents decreased from 42 13%(controlled) to 29 86%(50%N) and 20 17%(5%N) and 10 54%(5%N), P starvation will lead to the increase of total fatty acids (TFA), but the percentage of TPUFA tend to decrease. Si and Vitamin starvation will result in the increase of TPUFA( from 42 13% to 43 48% and 45 86%, respectively). |
