Mechanism of Action of Streptococcus downii, a New Bacterial Species with Probiotic Potential
نویسندگان
چکیده
Streptococcus downii is a recently reported bacterial species of oral origin, with inhibitory capacity against mutans, Actinomyces naeslundii, Veillonella parvula and Aggregatibacter actinomycetemcomitans, which confers upon it the potential being an probiotic. The aim present study was to identify mechanisms by S. exerts its effect on mutans. To this end, assessed consumption glucose proteins available in culture medium, modification pH, production short-chain fatty acids, changes protein panel inhibition halo, hydrogen peroxide proteinase K. There were no differences values or content but there reduction pH (with growth mutans). Significant increases detected levels lactic formic acid mutans), as well peptide maintained presence peroxidase disappeared after adding Based these results, suggested that main mechanism mutans bacteriocins.
