Study on Enzymological Properties of Linoleic Acid Isomerase from Lactobacillus acidophilus

Abstract

Abstract: The lionleic acid ismerase from Lactobacillus acidophilus was extracted to study its enzymological properties. The results indicated that the optimum temperature and pH value of lionleic acid ismerase are 40 ℃ and 4 respectively, and the ismerase exhibits strong stability to temperture (20 ～50 ℃) and pH value (4.0～6.0) for 1 h. Various metal ions and their respective concentrations have various effects on activity of the ismerase, and organic solvent as well. The Km of the ismerase is 33.33 mmol/L, and the Vmax is 15.6 mmol/L·h.

Key words: Lactobacillus acidophilus, lionleic acid ismerase, enzymological properties
