Plant growth promotion traits of phosphobacteria isolated from Puna, Argentina

open access: yesArchives of Microbiology, 2011
The ability of soil microorganisms to solubilize phosphate is an important trait of plant growth-promoting bacteria leading to increased yields and smaller use of fertilizers. This study presents the isolation and characterization of phosphobacteria from Puna, northwestern Argentina and the ability to produce phosphate solubilization, alkaline ...
