- ... 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 alkaloid ...

- ... The fungus P. citrinum produces secondary metabolites, clavinet ergot alkaloids (EA), and quinoline alkaloids (quinocitrinines, QA) in medium with various carbon and nitrogen sources and in the presence of iron, copper, and zinc additives. Mannitol and sucrose are most favorable for EA biosynthesis and mannitol is most favorable for QA. Maximum alkaloid production is observed on urea. Iron and cop ...
