Interacting Abiotic Factors Affect Growth and Aflatoxin B₁ Production Profiles of Aspergillus flavus Strains on Pistachio-Based Matrices and Pistachio Nuts.

ABSTRACT: Pistachio nuts are an economically important commodity produced by many countries. They can be colonized by mycotoxigenic fungi, especially Aspergillus flavus, resulting in contamination with aflatoxins (AFs), especially aflatoxin B₁ (AFB₁), a Class 1a carcinogen. The objectives were to examine the effect of interactions between the two key abiotic factors, temperature and water activity (a _w ) on (a) in vitro growth and AFB₁ production by four strains of A. flavus isolated from pistachio nuts, on a milled pistachio nut medium modified ionically (NaCl) and non-ionically (glycerol) in the range 20-35°C and 0.995-0.85 a _w , (b) colonization of layers of raw pistachio nuts stored at different inte
