Biosynthesis, regulation, and biological significance of fumonisins in fungi: current status and prospects

Critical reviews in microbiology, 2021
Fumonisins are one of the most important mycotoxin classes due to their widespread occurrence and potential health threat to humans and animals. Currently, most of the research focuses on the control of fumonisin contamination in the food supply chain ...

Identification and Characterization of an Aspergillus niger Amine Oxidase that Detoxifies Intact Fumonisins.

Journal of Agricultural and Food Chemistry, 2020
Fumonisin contamination of maize damaged by Fusarium verticillioides and related species is a major problem when it is grown under warm and dry conditions. Consumption of fumonisin contaminated food and feed is harmful to both humans and livestock. Novel

Fumonisins

International Journal of Food Microbiology, 1993
Fusarium moniliforme Sheldon is a common fungal contaminant of corn and produces a variety of mycotoxins. Among these are the recently discovered fumonisins, which are now known to cause certain animal diseases, namely leukoencephalomalacia in horses and pulmonary edema in swine.

Difficulties in fumonisin determination: the issue of hidden fumonisins

Analytical and Bioanalytical Chemistry, 2009
In this paper, the results obtained by five independent methods for the quantification of fumonisins B(1), B(2), and B(3) in raw maize are reported. Five naturally contaminated maize samples and a reference material were analyzed in three different laboratories.

Free and hidden fumonisins in raw maize and maize-based products from China

Food Additives & Contaminants, Part B, 2019
The occurrence of free and hidden fumonisins in raw maize and maize-based products from China was investigated. A total of 58 samples were analyzed using high-performance liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Among all the

Fumonisins and their analogues in contaminated corn and its processed foods – a review

Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment, 2018
One of the food security problems faced worldwide is the occurrence of mycotoxins in grains and their foods. Fumonisins (FBs) are mycotoxins which are prevalent in corn (Zea mays L.) and its based foods.

Analysis of heat-processed corn foods for fumonisins and bound fumonisins

Food Additives and Contaminants, 2004
Thirty retail samples of heat-processed corn foods, i.e. corn flakes, corn-based breakfast cereals, tortilla chips and corn chips, were analysed for fumonisins--fumonisin B1 (FB1), fumonisin B2 (FB2) and hydrolysed FB1 (HFB1)--as well as for protein- and total-bound FB1. Bound (hidden) fumonisins cannot be detected by conventional analysis.

Targeting Fumonisin Biosynthetic Genes

2016
The fungus Fusarium is an agricultural problem because it can cause disease on most crop plants and can contaminate crops with mycotoxins. There is considerable variation in the presence/absence and genomic location of gene clusters responsible for synthesis of mycotoxins and other secondary metabolites among species of Fusarium.

Fumonisin mycotoxins in human hair

Biomarkers, 2003
This study shows for the first time the accumulation of fumonisin mycotoxins in human hair of population clusters exposed to contaminated maize, and thus the feasibility of human hair analysis for the assessment of past fumonisin exposure. Composite hair samples were obtained from the Bizana, Butterworth and Centane districts within the Transkei region

Chemical Transformation of Hydrolyzed Fumonisin B1 to Hydrolyzed Fumonisin B2

Journal of Agricultural and Food Chemistry, 1995
The fumonisins, a series of sphingosine-analog mycotoxins produced by the ubiquitous corn contaminant Fusarium moniliforme, are an important food safety concern because they are tumor promoters with sufficient chemical stability to persist through normal food processing.
