摘要
2'⁃岩藻糖基乳糖(2'⁃fucosyllactose,2'⁃FL)在人乳寡糖中含量最高,占比可达30%。2'⁃FL能够有效促进婴儿大脑发育、提高婴儿免疫力,对青少年、成年人、老年人也大有裨益,已被广泛应用于婴幼儿配方奶粉、功能性食品饮料及医疗辅剂中。微生物合成2'⁃FL具有易实现大规模生产、可使用廉价原料作为底物等优势。目前2'⁃FL最主要的工业生产菌种为大肠杆菌,其他食品安全级菌株如酿酒酵母、枯草芽孢杆菌等也陆续被改造用来生产2'⁃FL,并已取得一定成效。该文对2'⁃FL作用于人体的机制、应用领域及2'⁃FL合成菌种构建现状等进行综述,并对未来发展趋势进行展望。
2'⁃fucosyllactose(2'⁃FL),accounting for about 30%of human milk oligosaccharides,is the most abundant oligosaccharide in human milk.Recognized for its potential to promote infant brain development,en⁃hance infant immunity,and provide benefits across different age groups,2'⁃FL has been widely used in infant formula,functional food and beverage,and medical adjuvants.Microbial synthesis of 2'⁃FL has the advantages of easy large⁃scale production and using cheap raw materials as substrates.At present,the main industrial pro⁃duction strain of 2'⁃FL is Escherichia coli,while other food safety strains such as Saccharomyces cerevisiae and Bacillus subtilis have also been modified to produce 2'⁃FL,with promising results.This review comprehen⁃sively discusses the mechanisms by which 2'⁃FL impacts the human body,its diverse applications,the current state of microbial strain engineering for 2'⁃FL synthesis,and offers insights into future trends in this field.
