| 摘 要： | 研究了25株嗜酸乳杆菌在MRS-CHOL培养基中对胆固醇的降解量,降胆固醇的能力,以及对酸、胆盐的耐受性。实验表明:所有实验菌株均有降解培养物中胆固醇的能力,其中有6株实验菌对培养物中胆固醇的降解率大于40%,这6株菌对胆固醇的脱除效力也较高,同时对这6株菌的耐酸、耐胆盐,以及对胆固醇的脱除能力进行了比较,筛选出降胆固醇能力较强同时对酸和胆盐耐受性较强的嗜酸乳杆菌1株。

| Abstract: | In this paper,25 Lactobacillus acidophilus were studied in the experiments.The quantity of the cholesterol-degrading in MRS-CHOL medium was used to analyze their cholesterol-reducing ability,then bile-tolerance and acid-tolerance.The results showed that all strains could remove cholesterol from media and removal rates of in which 6 strains were more than 40%.Meanwhile,these 6 strains had high removal effectiveness.As a result,these 6 strains were screened for their excellent cholesterol-reducing ability.Aci... |
