title: Production of the Mycotoxin Fumonisin B(1) by Alternaria alternata f. sp. lycopersici.
abstract: 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).
