Contamination of crop seeds and feed with Aspergillus flavus its associated aflatoxins presents a significant threat to human animal health due their hepatotoxic carcinogenic properties. To address this challenge, researchers have screened for potential biological control agents in peanut soil pods. This study identified promising candidate, strain the nonpigmented bacterium, Achromobacter xylosoxidans ZJS2-1, isolated from rhizosphere Zhejiang Province, China, exhibiting notable antifungal antiaflatoxin activities. Further investigations demonstrated that ZJS2-1 active substances (ZAS) effectively inhibited growth at MIC 60 μL/mL nearly suppressed AFB1 production by 99%. Metabolomic analysis revealed ZAS significantly affected metabolites involved cell wall membrane biosynthesis, leading compromised cellular integrity induced apoptosis A. through release cytochrome c. Notably, targeted SrbA, key transcription factor ergosterol biosynthesis integrity, highlighting crucial role ZJS2-1's biocontrol mechanism. Moreover, infection plant wilt caused can be efficiently alleviated ZAS. Additionally, inhibitory effects on various species, inhibition rates ranging 80 These findings highlight as agent against offering solution enhance food safety protect health.
