Under the optimal reaction conditions, the washed cells of Lactobacillus plantarum PTCC1058 produced 1661.26 mg of CLA/L reaction mixture (36% yield of production) from 4.6 mg/ml of castor oil after using 15% (w/v) cell for 121 h.The resulting CLA was mixture of two CLA isomers, cis-9, trans-11 (or trans-9, cis- 11)-octadecadienoic acid (CLA1, 44% of total CLA) and trans-10, cis-12-octadecadienoic acid (CLA2, 46% of total CLA). The total production of CLA is extracellular in all of the reactions performed with Lactobacillus plantarum PTCC1058. Also, Lactobacillus plantarum PTCC1745 produced 1590.31 mg of CLA/L reaction mixture (16.5% productionyield) from 9.6 mg/ml of castor oil after using 15% (w/v) cell for 121 h. Therefore, Lactobacillus plantarum PTCC1058 was suggested for CLA production due to its more production ability and CLA extracellular production.
