Obvious increase of EPA content of Nannochloropsis oculata achieved in temperature stresses

  • 摘要: 二十碳五烯酸(eicosapentaenoic acid,EPA)是一种长链多不饱和脂肪酸,是水产养殖动物幼体发育必需脂肪酸之一.富含EPA鲜活微藻、干燥微藻和冷冻微藻是水产养殖动物幼体重要的饵料[1].同时,EPA还能增强水产养殖动物免疫系统功能,提高成活率和抗病力[1~3].由于EPA含量是饵料藻品质的决定因素之一,品种选育、生态调控等提高EPA含量的措施均能提高微藻饵料价值.低温能提高微藻脂肪酸不饱和度,以维持生物膜流动性,抵抗低温伤害[4].另外,我们推测长链脂肪酸有可能提高微藻适应高温环境的能力.
