Taxonomy of Aspergillus section Flavi and their production of aflatoxins, ochratoxins and other mycotoxins.

ABSTRACT: Aflatoxins and ochratoxins are among the most important mycotoxins of all and producers of both types of mycotoxins are present in Aspergillus section Flavi, albeit never in the same species. Some of the most efficient producers of aflatoxins and ochratoxins have not been described yet. Using a polyphasic approach combining phenotype, physiology, sequence and extrolite data, we describe here eight new species in section Flavi. Phylogenetically, section Flavi is split in eight clades and the section currently contains 33 species. Two species only produce aflatoxin B₁ and B₂ (A. pseudotamarii and A. togoensis), and 14 species are able to produce aflatoxin B₁, B₂, G₁ and G₂: three newly
