  Article:   PHOSPHORUS MOBILIZATION FROM DIFFERENT INORGANIC PHOSPHATES BY BACTERIA PROPOSED FOR BIOFERTILIZER.

Authors:  . 		 
       
         
  Abstract:  Phosphorus is absorbed by the plants as orthophosphate anions (HPO42− and H2PO4−). The concentration of soluble phosphate in soil is low and it must be supplemented from other sources. Some of the bacteria with phosphate solubilising capacity are able to transform the accumulated insoluble phosphates in the soil into soluble forms, making them available for plants. Our aim was to assay phosphorus mobilization from different inorganic phosphates (calcium and iron phosphate, hydroxyapatite) by bacteria isolated from rhizospheric soil proposed for biofertilizer production.

Keywords: calcium phosphate, iron phosphate, hydroxyapatite, phosphorus solubilisation
