- A correlation was established between species specificity and synthesis of specific secondary metabolites by the Penicillium fungi. Strains of the subgenus Aspergilloides usually synthesize metabolites of polyketide nature. Most strains of the subgenus Furcatum produce clavine ergot alkaloids and metabolites of diketopiperazine nature. The only clavine ergot alkaloids and diketopiperazine alkaloids produced by strains of the subgenus Biverticillium are rugulovasines and rugulosuvines, respectively. Species designations of the strains of the subgenus Penicillium isolated from permafrost soil, the Mir orbital complex, and sites undergoing anthropogenic load were refined based on the marker secondary metabolites. Changes in the taxonomic position of some strains in the genus Penicillium are suggested.
