Trichothecenes and fumonisins produced in autoclaved tiger nuts by strains of Fusarium sporotrichioides andFusarium moniliforme Original Research Article

This work describes for the first time the production of trichothecenes and fumonisins in autoclaved tiger nuts by strains of Fusarium sporotrichioides and F. moniliforme respectively. The study was carried out using a high performance liquid chromatograph with fluorescence detector. The results obtained show that the strains studied are capable of producing these mycotoxins in tiger nuts and that the concentrations of toxin found depend on the variety of tiger nut used as substrate. The amount of type A trichothecenes produced in tiger nuts by the different strains of F. sporotrichioides is smaller than that produced by the same strains in other substrates. However, the strains of F. moniliforme have shown that their ability to produce fumonisin B1 is similar to that which they have in rice or wheat, although we have not found any detectable amounts of fumonisin B2 in tiger nuts.
