摘要:

羟基酪醇(hydroxytyrosol)又称3,4-二羟基苯乙醇(3,4-dihydroxyphenylethanol),是一类具有代表性的天然酚类化合物,广泛存在于橄榄等地中海植物中,具有较高的生物活性。研究表明,羟基酪醇具有显著的抗氧化、抗菌、抗炎和抗衰老等多重生理功能,在食品保鲜与包装、天然调味剂、保健品以及功能性食品开发等领域展现出广阔的应用前景和商业价值。当前,羟基酪醇主要通过植物提取或化学合成方式获得,但植物提取方式受到资源限制且产量有限,化学合成则存在反应条件苛刻、产物纯化复杂以及环境污染严重等问题,难以满足日益增长的产业化需求。近年来,基于合成生物学策略构建工程微生物,实现羟基酪醇的绿色高效生物制造,成为该领域的研究热点之一。微生物合成不仅具有环境友好、可持续性强和成本较低等优势,还为高选择性和高纯度生产提供了可能。本文综述了羟基酪醇的生物合成途径及其合成生物学改造策略,重点介绍了利用各种微生物底盘细胞实现羟基酪醇从头生物合成的研究进展。最后,对未来进一步通过合成生物学手段优化羟基酪醇的生物合成途径进行了展望,以期为羟基酪醇的合成生物制造规模化奠定基础。

Abstract:

Hydroxytyrosol (HT), also known as 3,4-dihydroxyphenylethanol, is a representative natural phenolic compound that is abundantly found in olives and other Mediterranean plants. It presents high biological activity and has been shown to possess a broad spectrum of physiological functions, including potent antioxidant, antimicrobial, anti-inflammatory, and anti-aging effects. Due to these properties, hydroxytyrosol holds great promise for applications in food preservation and packaging, natural flavoring agents, nutraceuticals, and the development of functional foods, with significant commercial and industrial potential. Currently, hydroxytyrosol is primarily obtained through plant extraction or chemical synthesis. However, plant extraction is limited by resource availability and typically lowyield, while chemical synthesis involves harsh reaction conditions, complicated purification processes, and environmental concerns, making it insufficient to meet the growing demand for industrial-scale production. In recent years, microbial biosynthesis based on synthetic biology approaches has emerged as a promising and sustainable alternative. This strategy enables environmentally friendly, cost-effective, and highly selective and high-purity production of hydroxytyrosol through engineered microbial cell factories. This review provides an overview of the biosynthetic pathways of hydroxytyrosol and the synthetic biology strategies for its enhancement, with a focus on the progress in utilizing various microbial chassis cells for de novo biosynthesis of hydroxytyrosol. Finally, the review discusses future perspectives on optimizing the biosynthetic pathways of hydroxytyrosol through synthetic biology, with the aim of laying a foundation for its large-scale production in synthetic biology-based manufacturing.
