Abstract
Native phosphate solubilizing bacteria were isolated from runner bean rhizosphere in order to study their effect on releases of soluble phosphorus from inorganic P sources. 34.37% of the rhizobacteria isolates solubilized CaHPO4 in the qualitative P-solubilization plate method after seven days of incubation. The best PSB isolates were selected for further study concerning P-solubilization in liquid culture. All these isolates showed higher potential for solubilization of inorganic P as indicated by the increase of P amount in the RPAM medium. Our results showed that PSB strains play a significant role in the acidification of the medium facilitating the P solubilization probably due to organic acid production.
