Selenium is a crucial micronutrient for human well-being, with significant contributions to antioxidant, anti-ageing, and antiviral activities. However, over one billion people globally struggle with selenium deficiency, leading to a pressing need for selenium supplementation. Conventional selenium-enrich food from plants and animals provides challenges in achieving precise selenium supplementation. Thus, it is crucial to discover selenium carriers that can be cultured in a controlled environment. Multiple studies have shown that microalgae are excellent carriers for selenium enrichment due to their rapid growth, suitability for plant consumption, ease of industrialization, high efficiency in converting organic selenium, and many others. This review focuses on single-celled microalgae, comprehensively reviewing their metabolic pathway, biological transformation, and valuable forms of selenium. Additionally, it forecasts the current application status and prospects of selenium-enriched microalgae in agriculture and global human health. This review provides a reference for the industrial supply of precise selenium-rich raw materials.

微藻：生物硒富集的良好载体


硒是人类健康的重要微量营养素，对抗氧化、抗衰老和抗病毒活性有重大贡献。然而，全球有超过 10 亿人与硒缺乏症作斗争，导致迫切需要补充硒。来自植物和动物的传统富硒食物为实现精确的硒补充带来了挑战。因此，发现可以在受控环境中培养的硒载体至关重要。多项研究表明，微藻是富含硒的极好载体，因为它们生长迅速、适合植物食用、易于工业化、有机硒转化效率高等。本文重点介绍单细胞微藻，全面综述其代谢途径、生物转化和有价值的硒形式。此外，它还预测了富硒微藻在农业和全球人类健康中的应用现状和前景。本文为精密富硒原料的工业供应提供了参考。
