RESUMO
Sixty two Fusarium isolates representing nine species from many parts of the world were screened for fusarochromanone production. A simplified method for the detection of fusarochromanone in culture filtrates or grain cultures was used. Under UV irradiation (364 nm) the chloroform phase from fusarochromanone-positive culture extracts fluoresced a characteristic bright blue color. Results were confirmed by thin-layer-chromatography comparison with pure fusarochromanone standards. Detection was possible in cultures as young as 1 week old. Biosynthesis of fusarochromanone was rare in Fusarium spp. and was only detected in three isolates of Fusarium equiseti, namely R-4482 (barley [Federal Republic of Germany]), R-6137 (barley [Alaska]), and R-8508 (potato [Denmark]), among all the isolates tested from various geographic sources.
