Secondary metabolites produced by plants or their symbionts have already shown specific properties: anticancer, anti-inflammatory, antibacterial, antifungal effects, etc. Astin C is a non-ribosomal peptide (secondary metabolite) produced by the fungus Villosirosea asteris, endosymbiont of the medicinal plant Aster tataricus, which has shown an interesting anticancer activity. The current challenge is the production of the molecule on a large scale and in higher quantities, either from the original fungus through fermentation technologies, or by a heterologous yeast strain having integrated the genes involved in the astin C biosynthesis pathway. The purpose of this workshop is to highlight the implementation possibilities of a strain producing a metabolite of interest. [less ▲]

Kluyveromyces marxianus S-2-05 and Kluyveromyces lactis S-3-05 were recently isolated from a traditional French cheese, Tomme d'Orchies, and characterized here for their advantages using a different application perspective. First, we established their anti-Salmonella activity and downregulation of the virulence sopD gene of Salmonella enterica subsp. enterica serovar Typhimurium, mainly in the presence of K. marxianus S-2-05. In addition to their antagonism, these non-Saccharomyces yeasts were able to survive under conditions mimicking the gastrointestinal environment and to form biofilms on an abiotic device such as polystyrene. These strains also displayed highly hydrophilic cell wall surfaces properties and capacity for adhesion to intestinal Caco-2 cells, thus enhancing their potential as probiotic strains. [less ▲]
