Cover Story: In a current context of microorganisms continuously outmatching antibiotics, uncovering new antimicrobial molecules is necessary. Tree barks represent an important quantity of wastes from forestry activities, while they are already known to potentially contain antimicrobial molecules. Among ten tree bark extracts, at least three demonstrated interesting antimicrobial activities. The extract from the wild cherry tree, Prunus avium, showed the strongest activities against Gram-positive bacteria and yeasts. It appeared that the extract also decreased the biofilm formation of methicillin-resistant Staphylococcus aureus. The presence of dihydrowogonin in significant quantities in the extract could be responsible for the antimicrobial and antibiofilm activities. Dihydrowogonin may represent a valuable antimicrobial resource from wild cherry bark wastes. View this paper
