Abstract- Phosphorous is an indispensible macro-element required for plant Nutrition. Phosphorous is found in soils both in an organic form and inorganic (minerals) form and its solubility in soil is low. Plants obtain P from soil solution as phosphate anion. Phosphate solubilizing Bacteria play vital role by elevating its availability to plants through release from organic and inorganic soil P by mineralization and solubilization.Primary mechanism in soil for mineral phosphate solubilization is lowering of soil PH by microbial production of organic acids and mineralization of organic P by acid phosphatases. Use of PSB as a bioinoculants enhances P uptake. In the present work, the efforts have made to isolate the phosphate solubilizing from agricultural soil followed by its biochemical characterization. In this study, isolation, screening and biochemical characterization of 50 isolates of phosphate solubilizing bacteria (PSB) from different soil samples of Latur region were carried out. Phosphate solubilizing activities of all isolates were tested on Pikovskaya Agar medium (PVK) by analyzing the clear zone formation. Further study has made to identify PSB using biochemical characterization. This article incorporates crucial information about phosphate solubilizing Bacteria (PSB) found in Agricultural soil of Latur region of Maharashtra.

Keywords: soil phosphorous, mineralization, soil solution, clearzone, phosphate solubilization.
