Mycotoxigenic fungi colonizing food matrices are inevitably competing with a wide range of other resident fungi. The outcomes of these interactions are influenced by the prevailing environmental conditions and the competing species. We have evaluated the competitiveness of F. culmorum and A. carbonarius in the grain and grape food chain for their in vitro and in situ dominance in the presence o...

Species of Aspergillus, Penicillium and Alternaria are major contributors to fruit and vegetable decay and to mycotoxin production during various stages of pathogenesis. The mycotoxins most commonly associated with fruits and vegetables and their products are aflatoxins, patulin, ochratoxin A and Alternaria toxins. Naturally occurring aflatoxins are found in fruits of tropical and subtropical r...

Aspergillus species are able to produce a range of mycotoxins, including e.g. aflatoxins, ochratoxins, fumonisins and patulin. Aflatoxins are mainly produced by members of Aspergillus section Flavi, and they contaminate various agricultural products in several parts of the world. Several recent reports have indicated that aflatoxin-producing fungi and consequently aflatoxin contamination occur ...

The aim of this study was to monitor the mycobiota of wine grapes, occurrence of ochratoxigenic microfungi in wine grapes and occurrence of ochratoxin A and Alternaria mycotoxins in fresh grape juice, must and wine from domestic crops in the year 2004. Thirteen samples of wine grapes (white /nine samples/ and red /four samples/) were collected during harvesting in the Znojmo wine region, SE Mor...
