Abstract
To develop high effiency biofertilizer, a bacterium having ability to solubilize inorganic phosphate was isolated from cultivated soils, using a sucrose minimal agar-hydroxyapatite medium. The strain was identified as Klebsiella sp. DA7l-1, based on the physiological and biochemical properties. The activity of solubilizing inorganic phosphate of Klebsiella sp. DA7l-1 against three types of insoluble phosphate such as tri-calcium phosphate, aluminium phosphate, hydroxyapatite were quantitatively determined. The results indicated that the strain solubilized hydroxyapatite. The MPS (mineral phosphate solubilizing) conditions of Klebsiella sp. DA7l-1, were measured to determine the optimal conditions. The optimal temperature and initial pH to solubilize insoluble phosphate in sucrose minimal medium were $30^{\circ}C$ and pH 6.0, respectively.
