Phosphate Solubilizing Microorganisms:-

Next to nitrogen phosphorus is another key element in plant metabolism and soil metabolism and in soil microbiological process. Phosphorus is an essential in seed formation and occurs in large quantities in plant, seed and fruit. Two symptoms of phosphate deficiency are produced on is plant size reduces and deep green colour of the leaves.

Phosphate Solubilisation:-

The most important aspects on phosphorus cycle are microbiological process of mineralization, solubilization and immobilization besides chemical fixation of phosphorus in soil.

The results of many laboratory studies have implicated the activities of soil microorganisms in the solubilization of inorganic soil phosphate. Solubilisation is due to microbial production of organic and inorganic acids which effectively dissolved inorganic phosphates and render them available to the soil flora and growing plants. In other words, phosphate solubilization is the process to dissolution of insoluble form of phosphate to soluble form by the action of microorganisms.

Many microorganisms produce lactic acid, glycolic citric and acetic acids which can solubilize such compounds as tri calcium phosphate, synthetic apatite and natural apatite microbial solubilization of inorganic phosphatic compounds is of great economic importance in plant nutrition phosphate solubilizing bacteria and fungi play an important role it converting insoluble phosphate compounds such as rock phosphate bone meal and basic slag, and particularly chemically fixed soil phosphorus into available form. These special types of microorganisms are termed as phosphate solubilizing microorganisms.

Phosphate solubulizing organisms involved influence the phosphate solubulizing rate in the soil. Bacillus megaterium, pseudomonas putida are the phosphate solubulizing Bacteria respectively fungi (VAM) are better solubuilizers than bacteria and other organisms.


Mechanisms of Phosphate Solubilisation:-

The Solubilisation of phosphate by microorganisms is attributed to excretion of organic acids like citric, glutamic, succinic, lactic, oxalic, oxalic, malic, fumaric, tartaric and alpha keto butyric. Bacillus megaterium and other microorganisms weather rock phosphate and tri calcium phosphate by decreasing the particle size reducing it to nearly amorphous forms. The action of organic acids has been attributed to their ability to form stable complexes with metallic elements. In addition to phosphate solubilization they can mineralize organic phosphate into a soluble form.
