| 摘 要： | 通过体外耐酸、耐胆盐实验,从新疆拜城赛里木镇传统拉丝酸乳中的优势乳酸菌中筛选出耐受性和优良益生特性较强的乳酸菌菌株.结果表明:筛选出来的9株乳酸菌,在pH 2.0的条件下表现出-强的耐受能力,S5-8和S2-1L用人工胃液处理后的活菌数量在108 CFU/mL以上,其中S5-8有明显的增长趋势,其他7株菌株活菌数量在107CFU/mL以上,远远超过了106 CFU/mL以上的临界值,对9株强耐酸性乳酸菌进行耐胆盐实验.

| Abstract: | In this study, we screened 9 potent probiotic strains with good acid and bile tolerance in vitro from the dominant
lactic acid bacteria of traditional fermented milk in Sayram, Baicheng County, Xinjiang, which is known as a town of
longevity in China. All 9 probiotic strains of lactic acid bacteria exhibited very strong tolerance to pH 2.0. The viable cell
counts of strains S5-8 and S2-1L were more than 108 CFU/mL after exposure to simulated gastric fluid, with S5-8 growing
vigorously. The viable cell counts of 7 other strains exceeded 107 CFU/mL, which were much higher than the critical value
of 106 CFU/mL. |
