Description
Summary:Secondary metabolites of 22 fungal strains (genus Aspergillus , section Usti ) isolated at diverse geographic regions, including the Arctic permafrost deposits, were studied. The studied strains were found to synthesize a variety of biologically active compounds, structurally identified as drimane sesqueterpenoids, isoquinoline alkaloids (TMC-120 A−C, derivative 1), meroterpenoids (austalides О and J), and anthraquinone pigments (averufin, versicolorin C). Desferritriacetylfusigen production by A. calidoustus isolates is reported for the first time. The individual spectra of secondary metabolites were used for reidentification of 17 strains, of which 15 were identified as A. calidoustus and two, as A. pseudodeflectus .
