Isolation and characterization of trichothecin from corn cultures of Fusarium graminearum MRC 1125


, : Isolation and characterization of trichothecin from corn cultures of Fusarium graminearum MRC 1125. Applied and Environmental Microbiology 54(7): 1700-1702

Trichothecin was isolated and purified from corn cultures of a toxic strain of Fusarium graminearum. This strain, designated MRC 1125, was obtained from corn in southern Africa. The brine shrimp toxicity assay was used throughout the isolation procedure to monitor the toxicity of the fractions. The compound was characterized by detailed 1H (500-MHz) and 13C (125-MHz) nuclear magnetic resonance spectroscopy and mass spectrometry. This is the first report of the production of trichothecin by a Fusarium species.
