Abstract

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