%X Many  soils  of  the  inter-tropical  regions  are  P-deficient  because  of  their  high  fixing  power  and  low  P content.  Rock  phosphate  resources  used  to  produce  the  phosphate  fertilizers  are  exhausted  and chemical   fertilizer   are   causing   environmental   degradation.   This issue   raised   thequestion   of sustainability of fertilization and subsequently has enhanced the interest in the use of microorganisms as  biofertilizers. The  aim  of  this  study is to  isolate  and  characterize potential P  solubilizing  bacteria (PSB) from  two  P  deficient  agricultural  regions  in  Senegal. Twelve potential  PSB were  selected  and further  screened  forother plant  growth  promoting  traits  (Indole-3-acetic  acid  (auxin)  and  siderophore production)  and  characterized  by  16S  rDNA  sequencing.  All  the  isolates  produced  auxin  and  sevenof them  produced  siderophore.  DNA  sequencing  showed  that  five  isolates  were  affiliated  to  the  genus Bacillus,four to the genus Staphylococcus, two to the genus Microbacterium and one isolate showed high  similarities  with  members  of  the  genus Burkholderia.The selected bacteria  will  further  be  tested onsomeplants to assess their biofertilization potential.
