title: Chemical and physiological characterization of taxa in the Fusarium sambucinum complex.
abstract: Forty-one isolates of Fusarium sambucinum sensu lato were screened for production of secondary metabolites in agar cultures. Of 16 strains of F. sambucinum sensu stricto all but two strains produced diacetoxyscirpenol and two unidentified metabolites, TB1 and TB2 respectively. The two remaining F. sambucinum strains produced T-2 toxin, TB1 and TB2. Fusarium venenotum (6 strains) produced diacetoxyscirpenol and an unidentified metabolite BB. Fusarium torulosum (8 strains) produced wortmannin and antibiotic Y. The three species could be differentiated by their pattern of identified and unidentified metabolites detected by agar plug TLC combined with chemical data from HPLC-diode array detection of fungal extracts, and data on growth rates on potato sucrose agar and tannin sucrose agar.
