10株益生菌益生特性的比较研究
Comparative study on probiotic properties of 10 strains probiotics
摘要
Abstract
10 strains of selected probiotics are studied with their probiotic properties such as bile salt tolerance ,degradation of cholesterol and triglyceride .Then the viable number of probiotics are detected when they are fermented in vegetable cultivation .On the basis of this , 7 strains of probiotics w hich have significant grow th‐promoting effect are pick up and used for investigating the change of total acid ,SOD enzyme and nitrite content .The result shows that the survival rate of LC ,LP and LGG are more than 30% ,when bile salt concentration was 0 .3% ,the degrading ability of cholesterol in LB ,LC ,LGG ,LP ,LCP ,and EF bacteria are 45 .63% ,48 .13% ,30 .63% ,23 .16% ,20 .63% and 16 .88% ,the degradation ability of triglyc‐eride for 5 strains probiotics containing LB ,LC ,LR ,Bb‐12 and EF are followed by 23 .06% , 16 .72% ,44 .6% ,31 .08% ,22 .9% ;the viable counts of St ,Bb‐12 and EF is less than 107 cfu/mL ,on the contrary ,the viable number of other 7 strains reach to 108 cfu/mL ;the total acid content of 7 strains bacteria are between 0 .4% and 0 .8% after fermenting for 24 hours ;LCP and LA produce SOD enzyme in the fermentation process ,the activity of SOD enzyme finally achieves 189 .09 U/mL ,the nitrite peak will disappear when adding LB ,LP ,LC ,LA and LGG ,the nitrite content is lower than 0 .2 mg/kg after 48 hours .关键词
