Co-occurrence of deoxynivalenol (DON) with other DON derivatives/metabolites and other Fusarium toxins, including zearalenone, nivalenol and as well as other mycotoxins (e.g. fumonisins) is frequently observed in food and feed. DON-3beta-glucopyranoside (DON-3-glucoside) was described as detoxification product of DON in wheat. This mycotoxin conjugate was observed in maize, barley, malt, beer a...

Conventional wisdom postulates that leaching losses of N from agriculture systems are dominated by NO(3)(-). Although the export of dissolved organic nitrogen (DON) into the groundwater has been recognized for more than 100 yr, it is often ignored when total N budgets are constructed. Leaching of DON into stream and drinking water reservoirs leads to eutrophication and acidification, and can po...

Enzyme-linked immunosorbent assays (ELISAs) are often employed for the control of deoxynivalenol (DON) in barley and other intermediates involved in beer production chain. Because of the occurrence of high levels of DON-3-glucoside (DON-3-Glc) in malt and beer that have been reported for the first time in our earlier study, research focused on the accuracy of DON determination by immunoassays i...

Access to bioavailable nitrogen often limits primary production in marine and freshwater ecosystems. Around 70% of nitrogen transported by rivers worldwide consists of dissolved organic nitrogen (DON), but its bioavailability has been poorly investigated. To assess the potential bacterial growth on DON, we developed a bioassay employing natural DON and bacterial inocula in medium manipulated to...

Background Deoxynivalenol (DON) is one of the most common mycotoxins found in cereal grains. Objective The purpose of this survey was determination of difference between DON fungal toxin pollution level in raw wheat flour and bread. Methods: In this In the present analytical-cross-sectional study, to determine DON level, 44 subjects were random samplings of wheat, bread and flour (Lavash and ...

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 ...
