Antagonism of nonaflatoxigenic isolated from peanuts against aflatoxigenic growth and aflatoxin B production .

section constitutes several species of opportunistic fungi, notable among them are and , capable of surviving harsh conditions and colonizing a wide range of agricultural products pre- and postharvest. Physical and chemical control methods are widely applied in order to mitigate the invasion of in crops. However, physical control is not suitable for large scale and chemical control often leads to environmental pollution, whereas biological control offers a safer, environmentally friendly, and economical alternative.

Modelling the effect of temperature and water activity on the growth rate of Aspergillus flavus and aflatoxin production in peanut meal extract agar.

Aspergillus flavus is the predominant species that produce aflatoxins in stored peanuts under favourable conditions. This study aimed to describe the growth and aflatoxin production by two A. flavus strains isolated from imported raw peanuts and to model the effects of temperature and a on their colony growth rate as a function of temperature and a in Peanut Meal Extract Agar (PMEA).

The effects of different packaging materials, temperatures and water activities to control aflatoxin B production by and in stored peanuts.

Aflatoxins (AFs) are secondary metabolites produced by aflatoxigenic strains of and , the most toxic being aflatoxin B (AFB). The purpose of the present work was to investigate the effects of industrial-grade packaging materials (low-density polyethylene, polypropylene, polyethylene-laminated aluminium); temperatures (25 °C, 30 °C); and water activities (0.74 , 0.
