This study investigated the synergistic effect of single inoculation and co-inoculation of phosphate-solubilizing bacteria (PSB) Pantoea rodasil LH-1and Burkholderia stabilis HS-7. Phosphate-solubilizing abilities of these strains were assessed by measuring phosphorus content in culture media that were singly inoculated or co-inoculated with these strains for 7 days. The co-inoculation of P. rodasil LH-1and B. stabilis HS-7 was found to release the highest content of soluble phosphorus (783.41 μg mL-1) into the medium, followed by single inoculation of B. stabilis HS-7B (743.90 μg mL-1) and P. rodasil LH-1 (736.59 μg mL-1). The highest pH reduction, organic acid production, and glucose consumption were also observed in the medium inoculated with both the strains, compared with that in the medium inoculated with the strain alone. Results of a plant growth promotion bioassay showed 7.7% and 15.5% higher leaf and root growth, respectively, in romaine lettuce coinoculated with P. rodasil LH-1and B. stabilis HS-7 than those inoculated with the strain alone. However, no significant difference was observed between single inoculation and co-inoculation of these strains with respect to phosphorus release and plant growth. Although the results of the present study did remarkdly not show the synergistic effect of phosphate solubilization by co-inoculation of the PSB strains examined, these results indicate that treatment with PSB exerts a beneficial effect on crop growth.
