Probiotics have health-beneficial properties mainly due to either a direct action on the host or the modulation of the host microbiota. Health-beneficial properties have also been associated with a variety of plant-derived molecules, widely used as dietary supplements. This study explores the possibility of combining the actions of probiotics and of plant-derived molecules by developing beneficial, probiotic-carrying, heterologous molecules. To this extent, spores of SF174, a well-characterized probiotic strain of
