Overview

This research evaluates growth dynamics and sporulation of non‐aflatoxigenic Aspergillus flavus strains, suggesting efficacy in biocontrol applications to mitigate aflatoxin.

Key Points

  • Non‐aflatoxigenic Aspergillus flavus strains showed superior growth and sporulation capacity at 30°C, enhancing potential for biocontrol applications.
  • Twenty consecutive subcultures confirmed the phenotypic stability of local non‐aflatoxigenic strains, ensuring retention of non‐aflatoxigenic characteristics over time.
  • The study identifies the pksA gene mutation as not responsible for aflatoxin production, linking its stability with environmental adaptability.
  • These non‐aflatoxigenic strains are promising candidates to reduce aflatoxin contamination in maize crops under variable climatic conditions.
