Abstract(s)

Biological control agents (BCAs) are beneficial living organisms used in plant protection to control pathogens sustainably. Lactic acid bacteria (LAB) have gained attention in biopesticides due to their safety as recognized by the Food and Drug Administration. These bacteria possess antifungal properties, demonstrating inhibitory effects through nutrient competition or the production of antimicrobial metabolites. Numerous Lactobacillus species have shown the ability to inhibit pathogenic microorganisms, primarily through acid production. The organic acids secreted by LAB reduce the pH of the medium, creating a hostile environment for microorganisms. These organic acids are a primary inhibition mechanism of LAB. This article reviews several studies on LAB as BCAs, focusing on their inhibition modes. Additionally, it discusses the limitations and future challenges of using LAB to control phytopathogens for sustainable agriculture.
