Antibacterial properties of the mycelium culture of Fomitopsis officinalis (Vill.: Fr.) Bondartsev et Singer were investigated. It was shown to be an additional source for production of antibacterial substances active against gramnegative bacteria. In the future, the use of Fomitopsis officinalis for production of antibacterial substances active against the pseudotuberculosis pathogen or pseudomonads is quite possible.
