The control of Aspergillus niger (A. niger) is of great significance for the agricultural economy and food safety. In this study, the antifungal effect and mechanism of iturin A from Bacillus amyloliquefaciens (CGMCC No. 8473) against A. niger (ATCC 16404) were investigated using biochemical analyses and ... and intracellular vacuolization. The cytomembrane integrity of A. niger was affected by iturin A, as detected by ... indicated that iturin A induced apoptosis in A. niger through the oxidative stress pathway. Proteomics results showed ...
