Abstract
The analysis of the absorption spectra of the low-molecular-weight nitrogen-containing secondary metabolites--alkaloids--of 4 Penicillium chrysogenum strains and 6 Penicillium expansum strains isolated on board the Mir space station showed that all these strains synthesize metabolites of alkaloid origin (roquefortine, 3,12-dihydroroquefortine, meleagrin, viridicatin, viridicatol, isorugulosuvin, rugulosuvin B, N-acetyl-tryptamine, and a "yellow metabolite" containing the benzoquinone chromophore).
