Fumonisins are mycotoxins produced by Fusarium verticillioides, a filamentous fungus that is a widespread pathogen of corn. The biosynthesis of fumonisins is catalyzed by an iterative modular polyketide synthase (PKS). The study of the biosynthetic mechanism for these reduced fungal polyketides has been challenging due to the difficulties in detecting the intermediates with a linear carbon chai...

Fumonisins are mycotoxins found in maize. In developing countries, the resources required for analysis are often lacking, and the shipping of maize between countries can be difficult since the importation of plant materials requires permits/ inspection to prevent the entry of pests that frequently infest maize. A simple, safe and legal method for shipping maize extracts to the USA was needed to...

Fumonisins are highly toxic metabolites produced by Fusarium proliferatum and verticillioides. Little is known about the effects of a chronic low level fumonisins on intestinal structure innervation in monogastric animals, even though intestine first organ exposed to fumonisins. The influence most prevalent strains fumonisins, FB1 FB2, liver morphology, enteric nervous system epithelial cell pr...

Fumonisins are mycotoxins produced by Fusarium species that commonly live in maize. Whereas fungi damage plants, fumonisins cause disease both to cattle breedings and human beings. Law limits set fumonisins tolerable daily intake with respect to several maize based feed and food. Chemical techniques assure the most reliable and accurate measurements, but they are expensive and time consuming. A...

Contamination by microscopic fungi and mycotoxins in high moisture corn (HMC) silages conserved by chemical additives was investigated. The samples were examined for the concentration and identification of microscopic fungi able to grow on Malt and Czapek-Dox agar and for mycotoxins content (deoxynivalenol, T-2 toxin, zearalenone and total aflatoxins, fumonisins, ochratoxins) by direct competit...

The occurrence of aflatoxins and fumonisins in Incaparina was investigated. Incaparina is a mixture of corn and cottonseed flour with added vitamins, minerals and a preservative. It has been marketed as a high-protein food supplement, particularly for children on protein-deficient diets. According to estimates, 80% of Guatemalan children in their first year are given Incaparina to provide an ad...

In the previous report, we developed methods for analyzing of trichothecenes and fumonisins using liquid chromatography-electrospray ionization tandem mass spectrometry (ESI-LC/MS/MS); ("Analysis of Trichothecenes in Barley Tea and Beer by Liquid Chromatography / Tandem Mass Spectrometry"; Shokuhin Eisei Gakkai 45, 307-312 (2004); "Analysis of Fumonisin B1 and B2 in Beer and Raw Materials of Be...

Fumonisins are mycotoxins produced by the maize pathogen Gibberel/a fujikuroi mating population A and frequently contaminate maize. Wild-type G. fujikuroi produces four B-series fumonisins, FB" FBz, FB3 and FB4 . These toxins are identical in structure except for the number and positions of hydroxyls along their linear carbon backbone. To elucidate the genetic and biosynthetic relationships amo...

BACKGROUND Fumonisins (a family of foodborne carcinogenic mycotoxins) cause health hazards to humans and animals in developing countries, and has also economic implications. Therefore, the efficacy of a novel environmental friendly nixtamalization procedure to make tortillas (the main staple food for the Mexican population) was investigated. METHODS Maize contaminated with 2136.67 ng/g total ...
