| Abstract: | A high conjugated linoleic acid (CLA) producer, Lactobacillus L1 (Lactobacillus sp.) was screened from 36 strains of lactic acid bacteria. The optimum conditions for CLA production in MRS medium were that concentration of linoleic acid was 0.1%(v/v), incubation time was 42hs. The enzyme that formed CLA was intracellular. It could be a multienzyme reaction for the formation of CLA from linoleic acid. We also set up a UV-scan and high performance liquid chromatography methods to determine CLA in this research. |
