Conclusion L. plantarum IFPL935 shows a protective effect on butyrate-producing bacteria and is able to improve colonic metabolism by promoting the formation of biologically significant compounds Reference: Tabasco, R., Sánchez-Patán, F., Monagas, M., Bartolomé, B., Moreno-Arribas, M.V., Peláez, C., Requena, T. 2011 Effect of grape polyphenols on lactic acid bacteria and bifidobacteria growth:resistance and metabolism.
