Production of the Mycotoxin Fumonisin B(1) by Alternaria alternata f. sp. lycopersici.
The mycotoxin fumonisin B(1), originally described as being produced by Fusarium moniliforme, was detected in liquid cultures of Alternaria alternata f. sp. lycopersici, a host-specific pathogen of tomato plants. The metabolite was detected by high-pressure liquid chromatography and mass spectrometry. Its identity was confirmed by fast atom bombardment and ion spray mass spectrometry, as well as parent-daughter tandem mass spectrometry. In three separate experiments, the concentrations found ranged between 5 and 140 ppm (mug/ml).
