Toxigenic cosmopolitan micromycetes of the genus Aspergillus: new facts of recent decades

The review presents an analysis of the current state problem associated with production toxic metabolites by three species fungi genus Aspergillus – A. flavus, niger and fumigatus. All them are known for their extensive occurrence in environment, pathogenicity traditional use industrial biotechnology. In recent decades aflatoxins, cyclopiazonic acid, fumonisins group B, gliotoxin clavine ergot alkaloids have been assigned to priority attention from whole variety structural types toxins peculiar these fungi. Large-scale studies flavus populations infecting agricultural products carried out many regions world, chemo- phenotypic composition has described, prospects molecular methods improving safety cultures replacement strains recommended biological correction shown, new information obtained confirming participation fumigatus development pathogenesis.
