RESUMO

Fusarium graminearum strains are well known for their role as plant pathogens and for their production of mycotoxins, and less known for their secretion of galactose oxidase, a well-studied and useful enzyme. Three galactose oxidase-producing isolates of F. graminearum were grown on rice to identify the production of zearalenone and trichothecenes through the use of thin layer chromatography and gas chromatography coupled to mass fragmentation. Detection and identification of deoxynivalenol, 3-acetyldeoxynivalenol, and zearalenone were accomplished.
