Production of fumonisins by Fusarium moniliforme strains from various substrates and geographic areas.
نویسندگان
چکیده
Strains of Fusarium moniliforme from different geographic areas and from corn and other substrates were tested for the ability to produce fumonisins in culture. The test results indicate that the potential exists for production of fumonisins by such strains in agricultural commodities and other substrates in widespread geographic areas.

Fumonisins are mycotoxins produced by Fusarium moniliforme, a common fungal contaminant of corn worldwide, 10 and F. proliferatum, a closely related species.l.Io.'9 The true incidence of F. moniliforme is difficult to determine because F. proliferatum has often been misidentified as F. moniliforme. lO,'3 Certain strains of F. proliferatum also produce moniliformin, but isolates of F. moniliform...

Fumonisins B1 (FB1) and B2 (FB2), two structurally related mycotoxins with cancer-promoting activity, were recently isolated from corn cultures of Fusarium moniliforme MRC 826. These toxins have been reported to be produced also by isolates of F. proliferatum. Contamination of foods and feeds by F. moniliforme has been associated with human esophageal cancer risk, and FB1 has been shown to be t...

A variety of toxic secondary metabolites including fumonisins, can be produced by the fungus Fusarium moniliforme and closely related species in section Liseola in large amounts (g/kg in laboratory cultures). Underivatized fumonisins were detected by HPLC using either an evaporative light scattering detector or electrospray MS. Electrospray MS used together with NMR and GC/MS was used to identi...

The fumonisins, a family of food-borne carcinogenic mycotoxins, were first isolated in 1988 (21) from cultures of Fusarium verticillioides (Sacc.) Nirenberg (previously known as Fusarium moniliforme Sheldon). During the same year, the structures of the fumonisins were elucidated (6) and fumonisin B1 was shown to cause equine leukoencephalomalacia (34). There have been numerous publications deal...
