Abstract
Lactic acid bacteria (LAB) are known for their various beneficial properties, including plant growth promotion and antagonistic effects against plant pathogens. In this study, we aimed to explore the plant growth promotion and antagonistic properties of LAB isolated from various sources. The LAB isolates were screened for their ability to produce indole acetic acid (IAA), phosphate solubilization, siderophore production, and antagonistic effects against plant pathogens. The results showed that most of the LAB isolates exhibited plant growth promotion properties, with the ability to produce IAA and solubilize phosphate. Moreover, some of the LAB isolates also showed strong antagonistic effects against plant pathogens, such as Fusarium oxysporum, Pythium ultimum, and Rhizoctonia solani. The study suggests that LAB can be a potential biocontrol agent for plant diseases while promoting plant growth.
