Aflatoxins are highly toxic carcinogens produced by several species in Aspergillus section Flavi. Strains of A. flavus that do not produce aflatoxins, called atoxigenic strains, have been used commercially in North America as tools for limiting aflatoxin contamination. A similar aflatoxin management strategy is being pursued in Nigeria. In the current study, loci across the 68 kb aflatoxin bios...

The density and aflatoxin content of individual cateye fluorescent cottonseeds have been investigated. In general, higher average levels of aflatoxin contamination were found among the lower density seeds. However, significant amounts of aflatoxins were detected in a few of the higher density seeds. Subjective evaluation of color and texture of dissected kernels indicated a predominance of poor...

aflatoxin is one of the most hazardous mycotoxins injurious to both humans and animals. aflatoxin contamination of crops is a serious economic loss inflicted upon agriculture, food and animal industry throughout the entire world. in nature, there are microorganisms able to alleviate aflatoxin contamination in crop products. in this work, the effects of four strains of bacillus subtilis in reduc...

Storage sheds like these Cameroonian corn cribs leave crops vulnerable to Aspergillus contamination. But contamination isn't always as obvious as it is on this ear of corn, and aflatoxin exposure can go undetected until health effects occur. Aid and development agencies are helping farmers learn how to spot and prevent Aspergillus.

Aflatoxins, produced by the fungus Aspergillus flavus, occur naturally in maize. Contamination of maize grain with aflatoxin is a major food and feed safety problem and greatly reduces the value of the grain. Plant resistance is generally considered a highly desirable approach to reduction or elimination of aflatoxin in maize grain. In this investigation, a diallel cross was produced by crossin...

Aflatoxins are highly toxic cancer causing fungal metabolites known to cause immune-system suppression, growth retardation, liver disease, and death in both humans and domestic animals. Human exposure to aflatoxins is limited by regulations that prohibit the use of crops containing excess quantities of aflatoxins for foods and feeds. Aflatoxins are regulated in part per billion (ppb) ranges wit...

in this study, binding ability of lactobacillus rhamnosus lgg to aflatoxin of pistachio was investigated. results indicate that the bacterium has aflatoxin surface binding ability of 35% (with initial concentration of 10 ppb aflatoxin) in exponential phase. acid and heat treatment increase this ability to 85%. in the second concentration of aflatoxin (20 ppb), this binding ability for viable ce...
