Antibacterial Activity of Wild Mushrooms from France

We selected seven wild Basidiomycota and Ascomycota mushrooms to evaluate their antibacterial activity: Cyclocybe aegerita, Cortinarius traganus, Gyroporus castaneus, Neoboletus luridiformis, Rubroboletus lupinus, Gyromitra esculenta, and Helvella crispa. Four mushrooms, three of which have never been tested, display antibacterial potential with MIC≤125 µg/mL against at least one Gram-positive bacterial strain. The cyclohexanic extract of G. esculenta possesses the strongest antibacterial activity with MIC=31 µg/mL against two strains of Staphylococcus aureus.
