Levels of mycotoxins produced by Fusarium species in genetically modified (GM) and near-isogenic maize, were determined using multi-analyte, microbead-based flow immunocytometry with fluorescence detection, for the parallel quantitative determination of fumonisin B1, deoxynivalenol, zearalenone, T-2, ochratoxin A, and aflatoxin B1. Maize varieties included the genetic events MON 810 and DAS-591...

background: deoxynivalenol (don) is a mycotoxin produced mainly by fusarium graminearum in grains such as wheat and maize. the aim of this study was to evaluate the inhibitory effects of citrus flavanones including, naringin (nar), hesperidin (hes), and neohesperidin (neo) on deoxynivalenol production using response surface methodology (rsm). methods: the studied flavanones were extracted from ...

fusarium head blight (fhb) or wheat scab is one of the destructive diseases that cause considerable loss in grain quality in cereal cultivated around the worldwide due to the production of trichotecen mycotoxin in the panicle. type b trichothecenes including nivalenol (niv), deoxynivalenol (don), 3-acetyl deoxynivalenol (3-acdon) and 15-deoxynivalenol (15-acdon) are considered to be major toxin...

Chemical analysis of the culture filtrates of Fusarium culmorum CMI 14764 has demonstrated the presence of seven trichothecene mycotoxins. Major metabolites are 3-acetyldeoxynivalenol and 7 alpha, 8 alpha-dihydroxycalonectrin, with 3,15-diacetyldeoxynivalenol, deoxynivalenol, calonectrin, isotrichodermin and 12,13-epoxytrichothec-9-ene (EPT) as minor products. The occurrence of the rarely encou...

Mycotoxin contamination is a significant health concern for human beings, but health risk assessments are usually based on one single mycotoxin, which might neglect the additive or competitive interactions between co-occurring mycotoxins [...].

Abstract Fusarium spp. are phytopathogens causing fusarium head blight in wheat. They produce mycotoxins, mainly fumonisins, deoxynivalenol, and zearalenone. The study was conducted during two growing seasons (2020 2021) at the experimental field laboratories of Hungarian University Agriculture Life Sciences (MATE). aim to determine influence season, nitrogen fertilisation, wheat variety on inf...

This study provides the first broad-scale investigation on the spatial and temporal occurrence of phytoestrogens and mycotoxins in streams in the United States. Fifteen stream sites across Iowa were sampled five times throughout the 2008 growing season to capture a range of climatic and crop-growth conditions. Basin size upstream from sampling sites ranged from 7 km2 to > 836,000 km2. Atrazine ...
