[Identification of aurofusarin in Fusarium graminearum isolates, causing a syndrome of worsening of egg quality in chickens].
Twenty isolates of Fusarium graminearum have been isolated from infested grain. When laying hens were fed with biomass of most isolates, the quality of eggs deteriorated. It was found that all the isolated produced a yellow-orange metabolite with an antibiotic activity against mycelial fungi and yeasts. The metabolite was identified by physico-chemical methods as the dimeric naphthoquinone aurofusarin. The production of the other mycotoxins zearalenone and deoxynivalenol by the fungal isolates did not evoke the syndrome of egg quality deterioration.
