Abstract

Effects of supplementing lactic acid bacteria on fecal microbiota, total cholesterol, triglycerides and bile acids in rats.

Highlights

  • Cholesterol is the archetypical steroid in mammals

  • In a previous study, we investigated the cholesterol-lowering effect of lactic acid bacteria screened from Inner Mongolia native meat sausages in China

  • To verify our in vitro results and investigate the effectiveness of L. p X3-2B ingestion in decreasing the risk of atherosclerosis, we investigated the cholesterol-lowering effect of fecal micro biota, triglycerides (TG), total cholesterol (TC) and total bile acid, in rats to further characterize factors affecting and correlation of its ability to hydrolyze cholesterol

Summary

Introduction

Cholesterol is the archetypical steroid in mammals. Hyper cholesterol associated with cardiovascular disease is one of the most important causes of death (Yıldız, Öztürk and Aslım 2011, Zhang et al 2012). Bile-salt hydrolase activity is observed in some strains associated with the gastrointestinal tract (Hyeong-Jun Lim 2004, Zhang et al 2008). In a previous study (unpublished), we investigated the cholesterol-lowering effect of lactic acid bacteria screened from Inner Mongolia native meat sausages in China. We defined the cholesterol-lowering effect of Lactobacillus plant arum X3-2B (L. p X3-2B)isolated from Inner Mongolia native meat sausages in vitro, and it was considered that the mechanism was incorporation of cholesterol into the L. p X3-2B. To verify our in vitro results and investigate the effectiveness of L. p X3-2B ingestion in decreasing the risk of atherosclerosis, we investigated the cholesterol-lowering effect of fecal micro biota, triglycerides (TG), total cholesterol (TC) and total bile acid, in rats to further characterize factors affecting and correlation of its ability to hydrolyze cholesterol
