| Popis: | Protective effect of Saccharomyces cerevisiae exometabolites (RF1 and RF2) on seven strains of propionic acid bacteria under exposure to bile salts and acid stress was studied. RF2 had a stronger protective effect than RF1. Comparison of the analytical profiles of RF1 and RF2, separated by RP-HPLC, showed that nearly 80% of RF1 components were present in RF2. Separation of S. cerevisiae RF1 into individual components by means of semi-preparative RP-HPLC was used for structural characterization of the active component of the RF1 fraction. It was found to contain two pentapeptides ( |
