The coupling effect of <i>Penicillium baileys</i> W2 in the <i>Aspergillus flavus</i> inhibition and peanut growth promotion.

ABSTRACT: Aspergillus flavus is a significant plant pathogen, and peanut crops are particularly vulnerable to aflatoxin contamination. This vulnerability underscores the need for more effective control methods. In this study, the strain Penicillium baileys W2 was isolated from the rhizosphere soils of healthy peanut seedlings. The fermentation extract exhibited concentration-dependent inhibition of pathogenic A. flavus growth, with a minimum inhibitory concentration (MIC) of 55 % and a minimum fungicidal concentration (MFC) of 60 %. Physiological data and transcriptome analysis demonstrated that the W2 fermentation supernatant inhibited A. flavus growth by disrupting membrane permeability. Metabolomics analysis identified active compounds, including propylparaben, taxifol
