Optimisation des conditions de culture pour la solubilisation de phosphate par des rhizobactéries

Abstract

The ability of phosphate-solubilizing bacteria (PSB) to solubilize phosphate is considered one of the most important traits associated with plant nutrition. In our study, 26 isolates of rhizospheric bacteria were obtained. These isolates were evaluated for their ability to solubilize tricalcium phosphate. The study of phosphate solubilization in liquid medium showed that the maximum solubilization rate was observed in isolate TP1 (6.5 μg/mL).
