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 bacteria play key roles in the biosynthesis and metabolism of CLA in rumen.

Key words: ruminal bacteria, biosynthesis, conjugated linoleic acid, isomer, capillary electrophoresis
