中文摘要:

      海洋硅藻三角褐指藻(Phaeodactylum tricornutum)含有丰富的岩藻黄素且生长速度快, 被认为是生产岩藻黄素的最佳物种之一。其中岩藻黄素作为一种天然类胡萝卜素, 具有抗肿瘤、抗氧化、抗糖尿病、抗炎症、抗肥胖等生理活性, 在生物医药和功能食品领域具有重要应用价值。岩藻黄素因合成机制的复杂性而表现出一定的不稳定性, 使其在生产中存在着产量低、成本高等问题。本文详细介绍了三角褐指藻源岩藻黄素的功能活性, 对岩藻黄素的合成机制及合成过程中不同因素对其积累量的影响因素的研究进展进行系统综述, 旨在深入研究海洋微藻来源的岩藻黄素的作用价值, 为岩藻黄素进一步的开发利用提供技术支撑, 有望为功能性食品领域的开发提供理论依据, 为未来海洋硅藻产业化发展提供参考。

英文摘要:

      The marine diatom (Phaeodactylum tricornutum) is rich in fucoxanthin and grows fast, which is considered to be one of the best species for fucoxanthin production. Fucoxanthin, as a natural carotenoid, has anti-tumor, anti-oxidation, anti-diabetes, anti-inflammation, anti-obesity and other physiological activities, and has important application value in the field of biomedicine and functional food. Fucoxanthin is unstable due to the complexity of synthesis mechanism, which leads to low yield and high cost in production. This paper introduced the functional activity of fucoxanthin from phaeodactyl trichodinium in detail, and systematically reviewed the research progress of fucoxanthin synthesis mechanism and the influencing factors of different factors on its accumulation during synthesis, aiming to further study the role value of fucoxanthin from marine microalgae and provide technical support for further development and utilization of fucoxanthin. It is expected to provide a theoretical basis for the development of functional food and a reference for the future industrialization of marine diatom.
