摘　　要：研究了对胆固醇和甘油三酯降解效果较好的益生菌降解能力,并采用高碘酸氧化法测定甘油含量,研究上清液不同组分降解能力.结果表明:胆固醇降解实验中,LB,LC,LP,LGG,LCP,EF上清液均有较好的降解能力,LB发挥降解作用的物质大部分为多糖类物质,LC,LP,LGG,LCP大部分为蛋白质,EF则全部为多糖类物质.甘油三酯降解实验中,LB,LC,LR,Bb-12上清液均有较好的降解能力,上清液中活性物质均为脂类物质,EF上清液无降解能力.甘油降解实验中,LC,LP,LCP对甘油具有较好的分解利用能力,其上清液中发挥降解作用的物质均有蛋白质,LC和LP的脂类物质也有较好降解作用.This paper discusses degradation ability of probiotics which have a good degradation effect on cholesterol and triglyceride.The glycerin content was detected by using periodate oxidation method and the degradation of different components in supernatant was also studied.The result shows that the supernatants of LB,LC,LP,LGG,LCP,EF have a good degradation ability in cholesterol degradation experiment,the substances in LB that exerts degradation function are mainly polysaccharides,whereas they are mostly proteins in LC,LP,LGG,LCP.However,for EF,they are all for polysaccharides.The supernatants of LB,LCP,EF have a good ability to degrade triglyceride.And the active substances of the supernatant are all lipids,while there is no degradation in EF supernatant.LC,LP,LCP have a good degradation ability for glycerol in glycerol degradation experiments.And their active substances in the supernatant are all proteins.It is also shown that the lipids of LC,LP have a good degradation ability.
