Environmental and Molecular Mutagenesis, EarlyView.Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

Qualitative Analysis of Aflatoxin from Aspergillus flavus isolates [PDF]
, 2009 Different isolates of Aspergillus flavus were isolated from five varieties of groundnut. These isolates were grown on liquid SMKY medium. By using TLC the cultural filtrate produced by these isolates were screened for Aflatoxin production. About 80% of A.

Fv antibodies to aflatoxin B1 derived from a pre-immunized antibody phage display library system [PDF]
, 2002 The production and characterization of recombinant antibodies to aflatoxin B[SUB1] (AFB[SUB1]), a potent mycotoxin and carcinogen is described. The antibody fragments produced were then applied for use in a surface plasmon resonance-based biosensor ...

An investigation into the transcription factors and regulatory mechanisms of Aspergillus
Food Safety and Health, EarlyView.Foodborne pathogen Aspergillus, a prevalent etiologic agent among filamentous fungi, are distinguished by a significant repertoire of transcription factors encoded within their genomes. These regulatory proteins are instrumental in orchestrating key biological processes, including cellular growth, secondary metabolite biosynthesis, mycotoxin production,

Chemical and biological evaluation of detoxified aflatoxin [PDF]
, 1976 Experiments were undertaken to evaluate testing procedures concerned with detoxification of aflatoxin in foods and feedstuffs. Specific experiments were undertaken to ascertain: (1) the percent decrease in the fluorescence of aflatoxin B1 when chemically
