Surfactins, a class of lipopeptide biosurfactants secreted by plant growth-promoting rhizobacteria (PGPR), have garnered significant attention due to their dual functionality in promoting growth and controlling diseases. Their potential as biopesticides is underscored unique physicochemical properties biological activities. However, the practical application surfactin currently limited its low yield natural strains. This study aimed optimize culture conditions for Bacillus velezensis BN, strain with exceptional biocontrol properties, enhance yield. Critical factors, including nitrogen sources amino acid supplementation, were systematically investigated determine impact on production. The revealed that supplementation pivotal factors influencing Compared baseline, these resulted remarkable 5.94-fold increase Furthermore, positive correlation was established between efficacy. Enhanced associated improved antifungal activity, biofilm formation, rhizosphere colonization capacity B. BN potato plantlets. These findings provide novel insights into establish scientific foundation development innovative eco-friendly agents suitable agricultural use. results demonstrate optimizing can significantly efficacy, thereby highlighting sustainable practices.
