摘要
乳酸菌利用低聚糖是其在肠道中定殖并发挥益生活性的必要条件,对其代谢机理的认识对于探索肠道内微生物的生理活动规律,促进人体健康有重要意义。本文综述了乳酸菌代谢低聚糖的作用机理,分别从糖转运系统、糖基水解酶类和代谢调控等方面对低聚果糖(FOS)、低聚半乳糖(GOS)、低聚木糖(XOS)、低聚异麦芽糖(IMO)、棉籽糖系列低聚糖(RFO)等代谢过程进行总结,并对未来的研究方向与热点进行展望。
Utilizing oligosaccharides is the prerequisite for lactic acid bacteria(LAB) in its colonizing and exerting probiotic activities in the intestinal tract. Comprehension of related metabolic mechanisms is of great significance for exploring the physiological rules of microbiota in the gut and promoting human health. The mechanism of oligosaccharides utilization by LAB was summarized, from the aspect of carbohydrate transportation systems, glycosyl hydrolases and metabolic regulation of fructo-oligosaccharides (FOS), galacto-oligosaccharides (GOS), xyloo-ligosaccharides (XOS), isomalto-oligosaccharide (IMO) and raffinose-family oligosaccharides (RFO), respectively. The tendencies of future research and development were also forecasted.
