L. plantarum ATCC 8014 as a probiotic have had the ability of CLA isomers production including cis-9,trans-11- 18:2 and trans-10,cis-12-18:2,CLA1 and CLA2, respectively, from castor oil that contains 89% ricinoleic acid. Results of this research have shown that addition of linoleic acid to the pre culture had positive effect on linoleate isomerase expression and it caused CLA isomers high production. Our results also indicated that concentration of substrate and incubation time are dramatically effective on the CLA isomers production. From these results 0.426mg/ml CLA1 and 0.371mg/ml CLA2 are produced from a reaction mixture includes potassium phosphate buffer (0.1M,pH 6.5), 8mg/ml castor oil and 0.1% tween 80, 100U/ml Lipase L-175 Sigma with 12%(wet) Biomass, under microaerobic condition and 37 °C for 72 hours.
