摘　　要：主要研究植物乳杆菌M1-UVs29在体外不同条件下降解胆固醇的作用。分别在添加不同含量的胆固醇、胆盐种类及含量,以及不同pH值的MRS培养基条件下,测定胆固醇的降低情况。结果表明,植物乳杆菌M1-UVs29具有降低胆固醇的能力,其降低方式主要为同化作用和共沉淀作用,且以同化作用为主。随着胆固醇含量的增加,降低率也随之增加,当胆固醇添加量为400μg/mL,接种量为4%时,胆固醇降低率最大值为42.55%;不同胆盐种类及含量对其降低率的效果也不同,当添加0.4%牛胆盐时,胆固醇降低率最大值为37.58%;pH值对胆固醇的降低率呈现先增大后减小的趋势,当pH值为5.5时,胆固醇降低率最大值为34.92%。The cholesterol degradation of Lactobacillus plantarum M1-UVs29 in vitro under different conditions is studied. In MRS culture medium with different content of cholesterol, bile salt type and concentration, and pH value, the cholesterol is determined. The results show that Lactobacillus plantarum M1-UVs29 has the ability to lower cholesterol, and its way mainly for assimilation and sedimentation, especially the assimilation. Along with the increase of cholesterol, the reducing rate also increases, when cholesterol concentration of 400 μg/mL, 4% inoculation quantity, cholesterol degradation rate of the maximum value is 42.55%; different bile salt species and concentration decreases the rate of the different also, when adding 0.4% bovine bile salts, cholesterol degradation rate reaches the maximum value （37.58%）; degradation of cholesterol pH ratio first increases and then decreases, when the pH is 5.5, the max degradation rate of cholesterol is 34.92%.
