Abstract

Sixteen Fusarium isolates belonging to F. graminearium Schw. and F. culmorum (W.G. Smith) Sacc. produced vomitoxin and zearalenone on cracked corn at 28 degrees C. Quantitation for vomitoxin was by gas-liquid chromatography. This toxin was produced in quantities of 5 to 236 microgram/g of fermented corn. Vomitoxin showed weak antibiotic activity against Penicillium digitatum Sacc., Mucor ramannianus Möller, and Saccharomyces bayanus Sacc., but did not inhibit gram-positive, gram-negative, or acid fast bacteria. The two molds and the yeast were inhibited by T-2 toxin at 5 micrograms, and diacetoxyscirpenol inhibited the molds at 5 micrograms and the yeast at 50 micrograms.

摘要

16株禾谷镰刀菌（Fusarium graminearium Schw.）和燕麦镰刀菌（F. culmorum (W.G. Smith) Sacc.）在28℃条件下于破碎玉米粒上产生呕吐毒素和玉米赤霉烯酮。呕吐毒素采用气液色谱法定量。该毒素在发酵玉米中的产量为5至236微克/克。呕吐毒素对指状青霉（Penicillium digitatum Sacc.）、拉曼毛霉（Mucor ramannianus Möller）和巴氏酵母（Saccharomyces bayanus Sacc.）表现出较弱的抗菌活性，但不抑制革兰氏阳性菌、革兰氏阴性菌或抗酸菌。这两种霉菌和酵母在5微克T-2毒素作用下受到抑制，二醋酸雪腐镰刀菌烯醇在5微克时抑制霉菌，在50微克时抑制酵母。
