| Abstract: | The presence of alpha-cyclopiazonic acid has been studied among metabolites of Aspergillus fungi. The study was performed with 138 cultures of 13 species obtained from the All-Russia Collection of Microorganisms and the collection of our institute. alpha-Cyclopiazonic acid was most frequently encountered among the metabolites of the section Flavi (the ability to synthesize alpha-cyclopiazonic acid was expressed in 61% of the strains of A. flavus, 83% of the strains of A. oryzae, and all strains of A. tamarii). This expression index for A. versicolor was less than 5%. We showed for the first time that alpha-cyclopiazonic acid is produced by A. fumigatus and A. phoenicis (expression in 30% of the strains of either species). |
