Phosphate solubilizing bacteria are decomposer bacteria functioning as major role in soilenrichment. That is because it is able to perform phosphate dissolution mechanism by excreting lowparticles weight of organic acids. The bacteria utilize simple carbon compounds (rootexudatesofplantsandthe restof theplant).Phosphate solubilizing bacteria activity will be high at atemperature of 300C - 400C. This study aims to isolate and identify thephosphate solubilizingbacteria intheconventional soil and organic soil originated from Japan. Conventional and organic soil sample aresent from Collage Of Agricultural Ibaraki University in Japan. The Isolation of pathogenic bacteria isperformed by the dilution method (platting method). Results of isolation of bacteria lisolates obtained 2on ground phosphate conventional solubilizing (TKO1 andTKO2) and 4 isolates of bacteria onsoilorganicsolubilizingphosphate(TOR1, TOR2, TOR3andTOR4). Bacteria lisolates TKO2 highestphosphate solubilizing. Based on the identificati on results using the Microgen ™ Kit GNA + B - IDSystem and Determine Bergeys 's Manual of Biology (Garrity et al., 2006)TKO2 isolate is identified asYersinia sp.Keywords : Phosphate solubilizing bacteria, conventional soil, organic soil, Yersinia sp.
