Abstract

The aim of this study was to evaluate the protective effects of exopolysaccharide (EPS) production on resistance to gastrointestinal digestive conditions and oxalate by probiotic strains of the species Lactobacillus rhamnosus, Lactobacillus fermentum and Lactobacillus brevis. The oxalate-degrading ability of the strains was determined using an enzymatic assay. The correlation between oxalate degradation rate and EPS production was not significant (P>0.05); however, the high-EPS-producing L.fermentumIP5 and L.brevisYG7 strains showed high oxalate-degrading activity, whereas the low-EPS-producing strain L.fermentumBP5 demonstrated low oxalate-degrading activity. The present findings suggest that dietary supplementation with the probiotic strain L.fermentumIP5 could be a promising strategy for the prevention of oxalate stone disease.
