摘要: Maize (Zea mays) and wheat (Triticum aestivum) collected in the foothills of Nepal Himalaya Mountains were analyzed for Fusarium species mycotoxins:  fumonisins, nivalenol (NIV), deoxynivalenol (DON). Predominant Gibberella fujikuroi mating population A (F. moniliforme) maize F. graminearum wheat; G. D proliferatum), acuminatum, avenaceum, chlamydosporum, equiseti, oxysporum, semitectum, torulosum also present. Strains produced strains NIV or DON. By immunoassay high-performance liquid chromatography, fumonisins >1000 ng/g 22% 74 samples. fluorometry, DON 16% samples but not detected wheat. Fumonisins eliminated by traditional fermentation producing beer, Nepalese rural urban women able to detoxify cont...
