低聚果糖能调节肠道菌群,有效地促进双歧杆菌、乳杆菌等乳酸菌在肠道的增殖,然而其代谢机理存在菌种特异性的特点。为了进一步了解乳酸菌代谢低聚果糖的状况,文中分别对乳酸菌负责低聚果糖代谢的转运蛋白、果糖苷酶及其代谢调控方式进行了总结,并对未来的研究方向提出了展望。

Fructooligosaccharides( FOS) have the ability to regulate the human intestinal flora,stimulating the growth and activity of certain strains of Lactobacillus and Bifidobacterium,but the molecular basis behind this is strainspecific. For further understanding the mechanism of FOS utilization by lactic acid bacteria,the transporters and the fructosidases which are responsible for FOS metabolism and the related regulation modes were summarized. The tendencies of future research and development were also forecasted.
