| 摘 要： | 采用氯仿-甲醇法提取紫球藻脂肪酸,探讨不同生长时期及光照等环境因素对紫球藻细胞脂肪酸组成的影响.实验结果表明,紫球藻在对数生长末期粗脂肪累积达到最大(12.84%),AA的含量在对数生长末期较高(20.65%),而EPA的含量则在对数生长初期达到较高(25%左右);强光照有利于紫球藻总脂肪的积累,弱光更有利于AA的合成,中等光强下的培养有利于EPA的积累;紫球藻在通气和最适生长pH下培养有利于PUFA的积累. |

| Abstract: | The method of chloroform-methanol is adopted to discuss the effect of environment factors on fatty acids composition of Porphyridium Cruentum.The result shows that the total fatty acids content of Porphyridium Cruentum can reach the furthest(12.84%) and the content of AA can reach 20.65% on logarithmic growth eveningphase,but the content of EPA can reach the furthest on logarithmic growth cubhoodphase, high light is propitious to the accumulation of total fatty acids, feeble light is propitious to increasing the concent of AA, and middling light intensity is propitious to accumulation of EPA,aeration and optimum pH can enhance the content of PUFA. |
| Keywords: | Porphyridium Cruentum fatty acids environment factors composition |
