Isolation and characterization of phosphate solubilizing bacteria from corn rhizosfer

Abstract The aim of this study was to isolate and characterize the Phosphate solubilizing bacteria from rhizosphere Zea mays L., Jeneponto Regency. This research conducted in several stages; i.e, sampling, medium preparation, sample dilution, isolation, characterization form gram staining, biochemical tests, quantitative tests phosphate solubility. Soil samples were diluted 0.9% NaCl soil containing microbes isolated on Picovskaya medium. Three isolates obtained which could dissolve phosphate, namely J2KN1, J3KR2, J3TG3 isolates. generally round shape with raised elevations, white, slimy, smooth, shiny surface, milky like coccus bacillus, gram-negative. Some had positive motility, indole, voges, methyl red, glucose, sucrose fermentation test. ability showed that J2KN1 highest concentration 51.1 μM, J3KR1 a 45.2 μM 37.6 respectively.
