In Vitro Cholesterol-Lowering Activity of Potential Probiotic Lactobacillus Plantarum Isolated from Chinese Sauerkraut

Abstract:

Nine Lactobacillus plantarum strains were isolated from the Northeast homemade sauerkraut and exhibited high cholesterol-lowering ability.By acid and bile tolerance and antimicrobial susceptibility testing,these strains were studied for their potenticl probiotic.The results showed good cholesterol-lowering ability with S56 giving the highest of cholesterol removal at 22.40μg/mL.All the strains could tolerate pH 3.0 and 10 g / L of bovine bile salt.Strains S2-6,S2-5,S4-1 and S56 maintained the growth for 1h at pH 2.0.
