摘要

母乳低聚糖（human milk oligosaccharides，HMOs）是母乳中仅次于乳糖和脂肪的第三大固体成分，具有调节免疫系统、维持消化健康及促进大脑发育等生理功能。近期，加州大学伯克利分校Patrick M. Shih基于合成生物学使能技术，在模式植物本生烟中重构HMOs代谢合成途径，利用太阳光能将CO

转化为系列HMOs。相关研究为HMOs的生物制造提供了新思路与新范例，扩宽了植物合成生物学在乳基功能营养品可持续发展领域的应用前景。从政策批准和工业应用等角度来看，上述技术仍处于“概念验证”阶段；相比之下，将CO

捕获催化与微生物细胞工厂发酵过程相结合的技术方案，更有望在短期内实现HMOs绿色生物制造的工业应用。

Abstract

Human milk oligosaccharides (HMOs) are the third largest solid component in breast milk. They have a wide range of applications due to their beneficial physiological functions such as regulating the immune system

maintaining digestive health

and promoting brain development. There is a growing interest in the development of green and efficient bioproduction of HMOs

via

synthetic biology technologies. Recently

Patrick M. Shih’s team from the University of California

Berkeley

has engineered the model plant

Nicotiana benthamiana

as a photosynthetic platform for HMOs production. Specifically

the enzymes involved in HMOs biosynthesis were heterologously expressed in the cytosol to reconstruct the metabolic pathways required for HMOs bioproduction. Furthermore

they optimized the productions of HMOs by enhancing the supply of key precursors. Finally

several HMOs were successfully produced from the cost-effective raw materials CO

. The reported study provides deeper insights into the green bioproduction of HMOs

and expands the potential applications of plant synthetic biology technologies in the green and sustainable bioproduction of other dairy-based functional nutraceuticals. From the perspective of regulatory approval and industrial application

the aforementioned technology remains at the proof-of-concept stage. In contrast

an integrated approach combining CO

capture and conversion with microbial fermentation shows greater potential for demonstrating scalable green biomanufacturing of HMOs in the near term.
