This study investigates the potential of Pythium oligandrum (strains M1 and 00X48) as a biocontrol agent in suppressing growth Fusarium culmorum production mycotoxins during malting naturally contaminated barley (Hordeum vulgare). The effects on F. culmorum-infected malt (BM) were evaluated through real-time PCR its impact mycotoxin was determined by quantitative analysis deoxynivalenol (DON) d...

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 ...

The contamination of feed with the Fusarium toxin deoxynivalenol (DON) decreases feed intake and daily gain of pigs but also affects their immune response (Étienne and Waché, 2008). Consequently, they could be predisposed to infectious disease. An experiment was conducted to evaluate the effects of a brief contamination of post-weaning feed with DON on performance and health condition during po...

abstractthe occurrence of deoxynivalenol (don) in retail foods in tehran (iran) was determined using high-performance liquid chromatography technique and immunoaffinity column as the clean-up step. a method was validated for analysis of don in rice, bread, puffed corn snack and wheat flour. the average recoveries and precision (rsd) for don in different foods ranged 84.2-93.1% and 2.9-12.0%, re...

Mycotoxins, as microbial secondary metabolites, frequently contaminate cereal grains and pose a serious threat to human and animal health around the globe. Deoxynivalenol (DON), a commonly detected Fusarium mycotoxin, has drawn utmost attention due to high exposure levels and contamination frequency in the food chain. Biological control is emerging as a promising technology for the management o...

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...

dissolved organic nitrogen (don) can react with disinfectants to produce numerous disinfectionbyproducts (dbps), particularly nitrogen-containing dbps (n-dbps), and produce serious adverse effectson public health. widely used biological processes in drinking water treatment can increase don in effluents,and enhance these ill effects. this study investigated don in a full-scale two-stage ozonati...

Seed-based pigeon diets could be expected to result in exposure of pigeons to mycotoxins such as deoxynivalenol (DON). Ingestion of low to moderate contamination levels of DON may impair intestinal health, immune function and/or pathogen fitness, resulting in altered host-pathogen interactions and thus different outcome of infections. Here we demonstrate that DON was one of the most frequently ...
