Antifungal activity of Meyerozyma guilliermondii: Identification of active compounds synthesized during dough fermentation and their effect on long-term storage of wheat bread

► 146 strains of yeasts were screened for the antifungal activity. ► Meyerozyma guilliermondii LCF1353 was selected for antifungal activity. ► Antifungal activity was characterized by in vitro assays. ► The synthesis of ethyl-acetate, ethanol and of a cell wall-degrading enzyme was shown. ► Breads fermented with the selected yeast were tested during storage.
