Abstract

The salt-affected soils of beach from Tianjin China were sampled to screen the saline tolerance phosphate-solubilizing bacteria (SA-T-PSB) using inorganic phosphorous medium. On basis of the phenotypic characterization and 16S rRNA gene sequencing, 4 isolates with the highest PSA, B1114, B1213, B1303, and J101 were identified as Enterobacter ludwigii, Pantoea ananatis, Pseudomonas psychrotolerans, and Gluconobacter frateurii, respectively. Subsequently, aimed to assaying the mechanisms of P-solubilizing, organic acid types of the 4 isolates were determined by high performance liquid chromatography. The results showed that all 4 isolates mainly secreted gluconic acid. The effect of carbon and nitrogen source on P-solubilization activity of the strains also indicated that the production of gluconic acid is the main mechanisms of P-solubilizing.
