Since deoxynivalenol (DON), the main representative of Fusarium toxic secondary metabolites, is a relatively common natural contaminant in barley, its traces can be detected in many commercial beers. Our previous study reporting for the first time the occurrence of relatively high levels of DON-3-glucoside (DON-3-Glc) in malt and beer prepared from relatively "clean" barley (semiscale experimen...

Abstract Mycotoxin contamination of maize often raises risks for human and animal health. The most frequently detected mycotoxins in are trichothecenes, fumonisins, aflatoxin. A total number 17,011 samples were tested by SGS their mycotoxin content between 2012 2017. toxin results clearly show that the southern areas country had higher levels than average. According to dataset, aflatoxin has be...

Contamination of Canadian barley samples by 3,15-diacetyldeoxynivalenol was detected by enzyme immunoassays combined with liquid chromatography-mass spectrometry. This is the first reported natural occurrence of this mycotoxin. The barley was infected mainly with Fusarium graminearum. Deoxynivalenol, 3-acetyldeoxynivalenol, and zearalenone were also found.

The trichothecene mycotoxin 3-acetyldeoxynivalenol was transformed by cultures of the diacetoxyscirpenol producer Fusarium sp. strain C37410-90 into four compounds, identified as deoxynivalenol, 15-acetyldeoxynivalenol, 3,15-diacetyldeoxynivalenol and fusarenon-X. The major transformations are the result of specific esterification and de-esterification processes, but the production of fusarenon...

Co-occurrence of emerging and regulated mycotoxins in contaminated samples has been widely documented, but studies about their combined toxicity are scarce. In this report, the deoxynivalenol, fumonisin B1 zearalenone, ones enniatin A, B beauvericin were tested SH-SY5Y human neuroblastoma cells. Their individual binary effects on cell viability mitochondrial function evaluated. The results with...

The objective of the performed investigations was to isolate pathogenic fungi from contaminated maize cobs, to assess the appearance of maize cob fusariosis and to determine grain contamination with deoxynivalenol in the cultivation of genetically modified maize containing a gene resistance against European corn borer (Ostrinia nubilalis Hbn) as well as selected non-modified cultivars. The plan...
