Six Leuconostoc mesenteroides strains isolated from camel (3) and sheep (1) milk, silage (1) and honey (1) have been investigated. All showed probiotic properties due to their resistance to gastrointestinal tract stresses, antibiogram profiles, hydrophobicity levels and antimicrobial activities against Staphylococcus aureus and Escherichia coli. Six had proteolytic, lipolytic, acidifying, and coagulation activities and five produced dextran. Metabolic flux analysis during growth in a sucrose-containing medium of two representative dextran-producing strains, and a non-producing strain revealed differences in the levels of the sucrose metabolites: fructose, glucose, lactic acid and mannitol, and a correlation between sucrose consumption and dextran synthesis for the producing strains. CM9 from camel milk showed high dextran production and the best pattern of intestinal tract colonization of gnotobiotic zebrafish embryos. These facts together with CM9’s technological and probiotic properties indicate that this strain may be useful for the production of functional dairy food.

从骆驼（3）和绵羊（1）牛奶，青贮饲料（1）和蜂蜜（1）中分离出六种Mesenteroides菌株。由于它们对胃肠道压力的抵抗力，抗菌素谱，疏水性水平以及对金黄色葡萄球菌和大肠杆菌的抗菌活性，均显示出益生菌性质。。六种具有蛋白水解，脂解，酸化和凝结活性，五种具有葡聚糖。在两个具有代表性的葡聚糖生产菌株和一个非生产菌株的含蔗糖培养基中生长过程中的代谢通量分析显示，蔗糖代谢产物的水平存在差异：果糖，葡萄糖，乳酸和甘露醇，以及蔗糖消耗量之间的相关性和葡聚糖合成用于生产菌株。骆驼奶中的CM9表现出较高的葡聚糖产量，并且是致敏的斑马鱼胚胎在肠道中定殖的最佳模式。这些事实以及CM9的技术和益生菌特性表明，该菌株可用于生产功能性乳制品。
