Abstract: | Species identification of slow-growing fungi of the genus Penicillium isolated from ancient permafrost deposits was performed using micro- and macromorphological characteristics as well as the composition of secondary metabolites. The strains producing clavine ergot alkaloids fumigaclavines A and B and festuclavine were assigned to the species P. palitans Westling 1911, whereas the strains forming ochratoxins A and B were identified as P. verrucosum Dierckx 1901. |
