A systems approach to model the relationship between aflatoxin gene cluster expression, environmental factors, growth and toxin production by Aspergillus flavus. [PDF]

open access: yes, 2011
A microarray analysis was used to examine the effect of combinations of water activity (a(w), 0.995-0.90) and temperature (20-42°C) on the activation of aflatoxin biosynthetic genes (30 genes) in Aspergillus flavus grown on a conducive YES (20 g yeast ...

Quantitation of aflatoxin B1 and aflatoxin B1 antibody by an enzyme-linked immunosorbent microassay [PDF]

open access: yesApplied and Environmental Microbiology, 1980
A specific microtest plate enzyme immunoassay has been developed for the rapid quantitation of aflatoxin B1 at levels as low as 25 pg per assay. Multiple-site injection of rabbits with an aflatoxin B1 carboxymethyloxime-bovine serum albumin conjugate was used for the production of hyperimmune sera. Dilutions of the purified antibody were air dried onto

Control of Aflatoxin Production of Aspergillus flavus and Aspergillus parasiticus Using RNA Silencing Technology by Targeting aflD (nor-1) Gene. [PDF]

open access: yes, 2011
Aspergillus flavus and Aspergillus parasiticus are important pathogens of cotton, corn, peanuts and other oil-seed crops, producing toxins both in the field and during storage.

Bioimprinting as a tool for the detection of aflatoxin B1 using a capacitive biosensor

open access: yesBiotechnology Reports, 2016
A strategy for the detection of aflatoxin B1 using a capacitive biosensor has been studied. The use of proteins for the generation of sites with high specificity against aflatoxin B1 are produced via bioimprinting.

Temporal monitoring of the nor-1 (aflD) gene of Aspergillus flavus in relation to aflatoxin B-1 production during storage of peanuts under different water activity levels [PDF]

open access: yes, 2010
Aims: A relative quantification system (RQ-PCR) was used to monitor the correlations between the activity of the nor-1 (=aflD) gene of Aspergillus flavus using real-time PCR in relation to phenotypic aflatoxin B-1 (AFB(1)) production and populations ...

Role of Biological Restraints and Vitamin E in Protecting the Reproductive System of Male Rats from Aflatoxin B1 Toxicity [PDF]

open access: yesTikrit Journal for Agricultural Sciences
This study aimed to investigate the effects of mycotoxins, specifically aflatoxin B1, and various bioadsorbents (yeast, zeolite, vitamin E) on the male reproductive system of rats by evaluating their impact on the levels of follicle-stimulating hormone ...

Adsorption of aflatoxin B1 on montmorillonite

open access: yesPoultry Science, 2005
The isothermal adsorption and the adsorptive mechanism of aflatoxin B1 (AFB1) on calcium montmorillonite (Mont) were studied in vitro trials. The maximum amounts of AFB1 on Mont in aqueous solution at 2 and pH 8 were 613.5 and 628.9 microg of AFB1 /g of Mont, respectively.
