Phosphorus plays a major role in growth and development of crops and is often found limiting in almost all types of soils. Phosphorus (P) solubilizing bacteria do the vital processes of mobilization of P from its poorly available sources. In this study, the potency of five bacterial strains (2 strains of Bacillus and 3 strains of Burkholderia) have been evaluated to solubilize P from complexes of Ca-P, Al-P, Fe(II)-P and Fe(III)-P. Bacillus amyloliquefaciens CTC12 (KT633845) solubilized P more efficiently from complexes of Ca-P, Fe(II)-P and Fe(III)-P where as Burkholderia cepacia KHD08 (KT717633) solubilized highest P from Al-P in vitro. All the five strains significantly enhanced soil phosphatase activities, microbial biomass P and plant P concentrations when combinedly applied with SSP. Bacillus amyloliquefaciens CTC12 and Burkholderia cepacia KHD08 in combination with SSP solubilized 63 and 61 per cent more P compared to pots treated with SSP only. When these five isolates were inoculated to groundnut enhanced the soil available P and phosphatase activity.
