Phosphate solubilizing bacteria

Phosphate solubilizing bacteria cultured in petri dish. The zone of n clearance can be clearly seen.

Phosphate solubilizing bacteria (PSB) are a group of beneficial bacteria capable of hydrolysing organic and inorganic phosphorus from insoluble compounds.[1] P-solubilization ability of the microorganisms is considered to be one of the most important traits associated with plant phosphate nutrition. It is generally accepted that the mechanism of mineral phosphate solubilization by PSB strains is associated with the release of low molecular weight

strain (P13) has been recently identified as the highly efficient insoluble phosphate solubilizer. Pseudomonas putida strain (P5), Microbacterium laevaniformans strain (P7) and Pantoea agglomerans strains, of all, three new biofertilizer /ha or 50 percent of the need for phosphatic fertilizers. Currently, different strains of these bacteria has been identified for using in 5O2, it can save about 50% of the crop requirement of phosphatic fertilizer. The use of PSB as inoculants increases the P uptake by plants. Simple inoculation of seeds with PSB gives crop yield responses equivalent to 30 kg Prock phosphate Currently, the main purpose in managing soil phosphorus is to optimize crop production and minimize P loss from soils. PSB have attracted the attention of agriculturists as soil inoculums to improve the plant growth and yield. When PSB used with [2]
