Özet
In this study, we report the effects of exposure to simulated gastric and intestinal juices on the survival of six strains of dairy propionibacteria. Gastrointestinal tolerance of propionibacteria strains was highly variable, depending on the strain and pH (P < 0.05). Exopolysaccharides (EPS) production of six propionibacteria strains under different pH conditions and bile concentrations was also studied. A positive correlation was obtained between the EPS production quantity of the strains and tolerance to simulated gastric juices at pH 2.0, 3.0 (P < 0.05). This investigation showed that high EPS production may be important in the selection of probiotic strains for resistance to upper gastrointestinal system conditions. © 2013 Society of Dairy Technology.
