Photoprotection Mechanisms and Crosstalk between the Biosynthesis of Fatty Acids and Astaxanthin in Haematococcus Pluvialis

Abstract

虾青素是一种重要的类胡萝卜素，具有良好的着色功能、超强的抗氧化功能及抗肿瘤作用，在水产养殖、食品添加剂、医药保健品等方面有着广泛的应用前景。单细胞雨生红球藻(Haematococcuspluvialis)在胁迫条件下能够积累大量的虾青素(约为细胞干重的4%)和中性脂肪酸(约为细胞干重的25%)。因此，雨生红球藻被认为是天然虾青素最好的来源。 雨生红球藻除了是虾青素等次级类胡萝卜素的最好天然来源外还是一种很有前景的生物柴油来源。生长迅速的雨生红球藻运动细胞常被用作在各种胁迫条件下生产虾青素和TAG的工作细胞。然而，由于运动细胞对胁迫环境比较敏感，诱导初期细胞死亡率高，使细胞生物量和目标产物产量...Astaxanthin, an important carotenoid, has been increasingly used in aquaculture industry, food additives, medicine and health products because of its color feature, excellent antioxidant activity, anti-tumor function. The green microalga Haematococcus pluvialiscan synthesize significant amounts of astaxanthin (~ 4% of dry cell weight, DCW) and storage neutral lipids (~25% of DCW) under adverse env...学位：工学博士院系专业：化学化工学院_工业催化学号：2062010015362
