The article reviews the role of soil beneficial bacteria, particularly plant growth promoting rhizobacteria (PGPR), in enhancing plant growth and soil health. PGPR are categorized into symbiotic and non-symbiotic types, with the former including nitrogen-fixing bacteria like *Rhizobium*, *Bradyrhizobium*, and *Azorhizobium*, and the latter including free-living nitrogen-fixing bacteria such as *Azospirillum*, *Enterobacter*, *Klebsiella*, and *Pseudomonas*. These bacteria promote plant growth through various mechanisms, including the production of specific compounds, facilitating nutrient uptake, and preventing plant diseases. They can also solubilize phosphorus, enhance soil structure, and improve soil organic matter content. The review highlights the importance of PGPR in sustainable agriculture, emphasizing their potential to reduce the need for chemical fertilizers and improve crop yields. Additionally, the article discusses the use of PGPR in bioremediation and their ability to control phytopathogens through the production of siderophores, antibiotics, and other antimicrobial compounds.The article reviews the role of soil beneficial bacteria, particularly plant growth promoting rhizobacteria (PGPR), in enhancing plant growth and soil health.
