Taxonomic position and nitrogen-containing secondary metabolites of the fungus Penicillium vitale Pidoplichko et Bilai apud Bilai

The type strain Penicillium vitale Pidoplichko et Bilai apud Bilai 1961 VKM F-3624 was found to considerably differ from a sibling species P. janthine llium (syn. P. simplicissimum) in some physiological and morphological feat ures (growth rates at different temperatures, the size of philiades, and th e shape of conidia), as well as in the pattern of the nitrogen-containing s econdary metabolites produced (roquefortine, 3,12-dihydroroquefortine, mele agrin, aurantioclavine, indole-3-acetic acid, and N-acetyltryptamine). The data obtained suggest that P. vitale represents an independent species.
