Sixteen Fusarium isolates belonging to F. graminearium Schw. and F. culmorum (W. G. Smith) Sacc. produced vomitoxin and zearalenone on cracked corn at 28°C. Quantitation for vomitoxin was by gas-liquid chromatography. This toxin was produced in quantities of 5 to 236 μg/g of fermented corn. Vomitoxin showed weak antibiotic activity against Penicillium digitatum Sacc., Mucor ramannianus Moller, 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 μg, and diacetoxyscirpenol inhibited the molds at 5 μg and the yeast at 50 μg.
