Summary:The aim of this study was to explore phosphate solubilizing bacteria in mangrove forest at Teluk Naga, Tangerang district, Banten. To collect samples, random sampling was applied. Bacteria were isolated by Pikovskaya media, using pour plate method. Nineteen isolates collected from soil demonstrated a potency to solubilize phosphate. Six isolates showed high phosphate solubilization activity from calculation of dissolution index. They were identified morpho-physiologically and biochemically as Pseudomonas (isolate R22 and A17), Klebsiella (A11, A14, A18, and A38), Agromyces (A13), Bacillus (A33 and A37), Azomonas (A15), and Enterobacter (A31 and A32). These bacteria were found in the rhizosphere of mangrove forests which consist of Avicennia and Rhizophora mangroves. These bacteria are known to have the ability to increase the availability of phosphate in the soil. This ability is one of the capabilities of the potential growth of promoting bacteria (PGPR or Plant Growth Promoting Rhizobacteria).
