[Advances in astaxanthin biosynthesis in Haematococcus pluvialis]

Astaxanthin is widely applied as a nutraceutical, pharmaceutical, and aquaculture feed additive because of its high antioxidant activity. Haematococcus pluvialis is a microalgal species that can largely accumulate astaxanthin under adverse environmental conditions. Here we review the research progress of astaxanthin biosynthesis in H. pluvialis, including the induction and regulation of massive astaxanthin, the relationship between astaxanthin synthesis, photosynthesis and lipid metabolism.虾青素是一种重要的次级类胡萝卜素，具有高活性的抗氧化功能，广泛应用于食品保健、医药、水产养殖等领域。雨生红球藻是一种在胁迫条件下能够大量积累虾青素的微藻。文中回顾了雨生红球藻虾青素的生物合成研究的进展，包括虾青素生物合成的诱导与调控、虾青素合成与光合作用及脂类代谢的关系等研究现状。.
