What are Plant Growth Promoting Bacterias (PGPB)?

Plant growth promoting bacteria (PGPB) are bacteria that can enhance plant growth and protect plants from disease and abiotic stresses through a wide variety of mechanisms. Plant growth promotion (PGP) qualities include biological nitrogen fixation, phosphate solubilization, ACC deaminase activity, and siderophores and phytohormone synthesis. If bacterial inoculants are effective, they can help boost agronomic efficiency by lowering production costs and reducing pollution, especially if chemical fertilisers are decreased or eliminated.
