Production of refusal factors by Fusarium strains on grains

Abstract
Corn fermented with strains of Fusarium culmorum NRRL 3288, F. poae NRRL 3287, F. moniliforme NRRL 3197, and F. nivale NRRL 3289 at 28 degrees C for 13 days was refused when fed to 30- to 60-pound (about 13.6- to 27.2-kg) swine. Analyses of the refused corn for trichothecenes (T-2, HT-2, acetyl T-2, fusarenon-X, and vomitoxin) showed that only the corn fermented with F. culmorum contained vomitoxin. None of these five trichothecenes could be detected in the other refused corn.F. culmorum grown on rice at 28 degrees C for 13 days also produced vomitoxin.
