[An in vitro study of cholesterol-lowering properties of probiotics isolated from the human feces].
21 strains of Lactobacillus and Bifidobacterium, isolated from feces of healthy youth and children feces and identified by molecular biological methods, together with 6 strains of probiotics preserved in Onlly lab were studied in the experiments, including removal cholesterol from media, bile-tolerance and acid-tolerance. The results demonstrated that all strains could remove cholesterol from media and removal rates of 5 strains were more than 40%. Meanwhile these 5 strains had high removal effectiveness. The bile-tolerance and acid-tolerance were varied from strain to strain. Among 27 strains, Bm26 demonstrated higher ability of removal cholesterol, bile-tolerance and bile-tolerance than other strains.
