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 not been tested to date, displayed antibacterial potential, with a minimal inhibition concentration (MIC) of <= 125 mu g/mL against at least one Gram-positive bacterial strain. Cyclohexanic extract of G. esculenta possessed the strongest antibacterial activity, with an MIC of 31 mu g/mL against two strains of Staphylococcus aureus.
