Dual defense mechanisms from a novel marine fungus Nigrograna chlamydospora sp. nov. B143: antifungal and anti-aflatoxigenic properties against Aspergillus flavus

Introduction: was isolated from a marine environment, highlighting its potential for biocontrol applications in food and agriculture. Methods: . Transcriptome analysis was conducted to identify differentially expressed genes in aflatoxin and ergosterol biosynthesis pathways. Fluorescence staining was used to assess cell wall and membrane integrity, as well as oxidative stress. Results: . Discussion: growth and aflatoxin production, underscoring its potential as an effective biocontrol agent for mitigating contamination in food and agricultural products.
