Abstract

Eighteen Fusarium crookwellense isolates from the continents of Australia, Europe, and North America were compared for their ability to produce mycotoxins on corn at 25 degrees C after 2 weeks. Extracts from corn fermented with each Fusarium isolate were analyzed by thin-layer chromatography (TLC) and gas chromatography/mass spectroscopy (GS/MS) for mycotoxins. Toxins detected were zearalenone (13 isolates), fusarin C (11 isolates), nivalenol (4 isolates), and diacetoxyscirpenol (2 isolates). Zearalenone and fusarin C were produced by isolates from each continent, while nivalenol was detected in the Fusarium isolates originating from Australia and one isolate from the United States.

摘要

对来自澳大利亚、欧洲和北美洲的18株克劳威尔镰刀菌分离株在25摄氏度下培养2周后在玉米上产生霉菌毒素的能力进行了比较。用薄层色谱法（TLC）和气相色谱/质谱联用仪（GS/MS）分析了每种镰刀菌分离株发酵玉米的提取物中的霉菌毒素。检测到的毒素有玉米赤霉烯酮（13株分离株）、镰刀菌素C（11株分离株）、雪腐镰刀菌烯醇（4株分离株）和二醋酸藨草镰刀菌烯醇（2株分离株）。每个大陆的分离株都能产生玉米赤霉烯酮和镰刀菌素C，而在源自澳大利亚的镰刀菌分离株以及1株来自美国的分离株中检测到了雪腐镰刀菌烯醇。
