摘要

目的研究罗伊乳杆菌LE16的益生特性。方法通过体外和动物实验,评价罗伊乳杆菌LE16的益生特性。结果该菌株对p H 2.5的强酸和0.3%高胆盐环境均有良好的耐受性。对引起肠道感染的几种病原菌均有不同程度的拮抗,尤其对枯草芽胞杆菌、伤寒沙门菌、单核细胞增生李斯特菌及蜡样芽胞杆菌的抑制作用最强。对肠道菌群正常和失调的小鼠均具有调节功能。结论罗伊乳杆菌LE16具有良好的益生性能,可作为益生菌菌株开发应用于食品和保健食品中。
        Objective To study the probiotic properties of Lactobacillus reuteri LE16. Methods The probiotic properties of Lactobacillus reuteri LE16 were evaluated with in vitro animal experiments. Results Lactobacillus reuteri LE16 showed high tolerance to p H 2. 5 and 0. 3% oxgall environment. It exhibited a broad inhibitory effect on enteric pathogenic bacteria,especially Bacillus subtilis,Salmonella typhimurium,Listeria monocytogenes and Bacillus cereus. It also had regulatory effect on normal or imbalanced intestinal flora in mice. Conclusion Lactobacillus reuteri LE16 shows excellent probiotic properties. It can be developed and used in food and health food as a protiotic strain.
