A total of 122 wheat varieties obtained from the Nordic Genetic Resource Center were infected artificially with an aggressive Fusariumasiaticum strain in a field experiment. We calculated the severity of Fusarium head blight (FHB) and determined the deoxynivalenol (DON) content of wheat grain, straw and glumes. We found DON contamination levels to be highest in the glumes, intermediate in the s...

Four strains of Butyrivibrio fibrisolvens did not degrade aflatoxin B1. Acetyl T-2 toxin, T-2 toxin, HT-2 toxin, deoxynivalenol, diacetoxyscirpenol, verrucarin A, zearalenone, and ochratoxin A did not affect the specific growth rate of B. fibrisolvens CE51 significantly, but all were degraded to greater or lesser extents. Breakdown products were produced as a result of deacetylation reactions.

In this work, we studied the impact of harvesting time on Fusarium mycotoxin occurrence in spring wheat and effect contamination quality these grains. The grains (Triticum aestivum L.) were collected 2016–2018 when crop had reached full maturity, 10 ± 2 days 17 3 after maturity. grain samples analyzed for infection co-contamination with mycotoxins deoxynivalenol (DON), zearalenone (ZEA), T-2 to...

To determine if deoxynivalenol (DON) is concentrated in small corn screenings, fourteen to twenty-three 1.1 kg test samples were taken from each of 10 barges of shelled corn. Each of the 181 test samples was divided into 2 components (fines and clean) using a 5 mm screen. The clean component sample rode the 5 mm screen and the fines component sample passed through the 5 mm screen. The DON conce...

Deoxynivalenol (DON) is a mycotoxin found in cereal grains and cereal-based foods. DON concentrations in finished products are reduced under some processing conditions, but not others. DON concentrations in flour, wheat and selected foods made from them under commercially relevant conditions were compared by GC with electron capture detection. Average concentrations (n = 9/item) in cookies, cra...

To determine the reasons for the natural occurrence of nivalenol in the northernmost area of Japan, scabby wheat was harvested from 19 crop fields in Hokkaido. Mycological surveys and analysis for mycotoxin contamination were performed. Among 13 wheat grain samples harvested in seven locations, 9, 2, and 6 samples were positive for deoxynivalenol, nivalenol, and zearalenone, respectively, at le...
