Aspergillus flavus is the main producer of carcinogenic aflatoxins and thus is one of the most important fungal food contaminants. Here, we report that the genome of A. flavus strain MRI19 was sequenced using MiSeq and PacBio platforms and that a hybrid assembly was generated.

Aflatoxin contamination of corn can occur when developing kernels are infected by the plant pathogen Aspergillus flavus. One route of infection is from airborne conidia. We executed a series of experiments within the corn canopy during two growing seasons and in two states to document the abundance and dynamics of the airborne A.

Background: This study employed melanin synthesized by Aspergillus flavus and Aspergillus carbonarius to inhibit the production of mycotoxins and bioremediation of heavy metals (HMs).
Methods: First, twenty fungal isolates were obtained from soil samples, and were evaluated to produce melanin. The melanin of the most potent producers has undergone several confirmatory experiments, including, Dihydroxyphenylalanine (DOPA)-inhibitor-kojic acid pathway detection, High-performance liquid chromatography (HPLC), Fourier-transform infrared (FTIR) and Nuclear magnetic resonance (NMR).

Peanut seeds are enriched with protein and fatty acids, making them susceptible to infection by Aspergillus flavus (A. flavus). The infected seeds are harmful to human health due to the aflatoxin contamination.

The isolated Aspergillus flavus NSRN22 was used for green synthesis of silver and selenium nanoparticles (AgNPs and SeNPs). New food packaging films produced by combining each type of NPs with chitosan (CS) or sodium alginate (SA) were characterized. Transmission electron microscopy revealed that the average particle size was lower in case of AgNPs (9 to 14.
