Abstract: Aspergillus flavus Link is frequently isolated fungi in environmental studies.This species produces sclerotia, a phenotypic feature that has been related tothe production of aflatoxins and cyclopiazonic acid. The objective of this studywas to analyze the characteristics of the sclerotia of environmental strains ofA. flavus due to their relationship with mycotoxin biogenesis. The sclerotia of14 strains from the Microbial Culture Collection of the Faculty of Biology weremeasured and the qualitative detection of aflatoxins and cyclopiazonic acidwas performed. All sclerotia produced were of the L morphotype (> 400 μm)and the presence of aflatoxins or cyclopiazonic acid was not detected.Knowledge of the morphological characteristics of these resistance structuresand their relationship to the biogenesis of mycotoxins in populations of thisspecies contributes to knowledge of their diversity in the neotropics.
