We examined the effect of using xylose as a carbon source in the medium on trichothecene production by Fusarium graminearum. By frequently adjusting the pH of the submerged culture in response to the pH changes of the known trichothecene- inducing sucrose-agmatine culture, trichothecene became detectable from the xylose liquid culture initiated at neutral pH. In contrast to the low pH requirement of the xylose medium for trichothecene production, the fungus produced the mycotoxin in sucrose liquid culture at neutral pH.
