| 摘 要： | 为了解瘤胃细菌生物合成共轭亚油酸(CLA)的特性，通过毛细管电泳(CE)分析，发现瘤胃细菌生物合成CLA的主要异构体有c9,t11-CLA、t10,c12-CLA和t9,t11-CLA 3种。在厌氧和有氧条件下，瘤胃细菌均能合成CLA，且氧气有利于CLA的累积，随反应时间的延长，CLA的量呈现先增加后减少的变化趋势。结果表明瘤胃细菌参与了反刍动物体内CLA异构体的生物合成与代谢，瘤胃细菌生物合成CLA异构体的特异性还有待更深入的研究。

| Abstract: | In order to understand accumulation properties of conjugated linoleic acid(CLA) biosynthesized by ruminal bacteria,capillary electrophoresis(ce)was used to analyze CLA isomers.Three main isomers including c9,t11-CLA,t10,c12-CLA and t9,t11-CLA were synthesized by ruminal bacteria under both anaerobic and aerobic conditions.Aerobic environment was more beneficial for the accumulation of CLA than anaerobic environment.The yield of CLA exhibited a trend of initial increase and final decrease.Therefore,ruminal b... |
