Plant growth-promoting rhizobacteria (PGPR) affect plant growth via various direct or indirect mechanisms. These microorganisms are the potential tools for sustainable agriculture. In this study, eight different Pseudomonas strains (PM1 - PM8) isolated from rhizospheric soil were characterized plant growth-promoting characteristics, including indole-3-acetic acid (IAA) and Gibberellin (GA₃) production, phosphate solubilization, 1- aminocyclopropane-1-carboxylic acid (ACC) deaminase activity and effects of direct inoculation on plant growth parameters (fresh weight, shoot length). All of these strains have their ability for solubilization of insoluble phosphate depending on pH decrease at the range around pH4 - 5 at 2 days after inoculation. PM1, PM4, PM5 and PM7 species was capable of IAA production and PM4, PM5, PM7 and PM8 species have high activity for production of gibberellin (GA₃) hormone. For ACC deaminase activity, PM1, PM3 and PM8 show high activity. Furthermore, all these species have significantly promoted the growth of the lettuce seedling plants for fresh weight and shoot length enhancement, so that these Pseudomonas species could be used as potential bio-fertilizer agents.
