Abstract

SUMMARY: A spectrofluorometric assay for the estimation of the tremorgenic mycotoxin verruculogen in crude mycelial extract has been devised and used to determine concentrations as low as 0·2 μg ml. Verruculogen production by has been extended from surface culture to submerged culture in 60 1 stirred fermenters, in which the maximum cell-associated mycotoxin yield [5 mg (100 ml culture)] was obtained within 7 d. It was found necessary to supplement the medium (Czapek Dox broth plus 0·5% yeast extract) with calcium chloride (2%) to induce profuse sporulation (2 × 10 conidia ml).
