摘要

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 M?ller, 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.
