The fusarins produced by seven Fusarium moniliforme strains grown in liquid culture were analyzed and characterized. Three fusarins were observed and identified, fusarin A [2], fusarin C [1], and a fusarin which had not been previously described, fusarin F [4]. No significant amounts of fusarin B or fusarin D [3] were detected. The time course of production of fusarins A, C, and F in liquid culture fermentations is described.
