Abstract. Ikhwani, Saribanon N, Setia TM, Yuniarti E, Jumakir. 2021. Nitrogen-fixation and phosphate-solubilization bacteria isolated from alluvial and latosol soil paddy field. Biodiversitas 22: 4722-4730. This study aims to isolate, select and identify molecular characterization of bacteria from alluvial and latosol soil paddy field. This study has been conducted from February-June 2020 in the Soil Biology Laboratory, ICALRRD, Bogor. Alluvial and latosol soil samples were selected from Pusakanagara and Muara experimental gardens, Muara district. The result showed that bacteria growth in N-free media was higher from latosol soil as compared to alluvial soil. The higher nitrogenase activity isolates, could form ethylene gas concentration 1.1.E + 09 µmol/mL/hours, 1.7.E + 09 µmol/mL/hours and 1.3.E + 09 µmol/mL/hours from alluvial 6, latosol 4, and latosol 9. Three isolates have great PSB performances, i.e. isolates No. 4.2, 2.1 and 2 could dissolve 14.398 mg l-1, 12.648 mg l-1 and 12.145 mg l-1 of phosphate, from latosol soil. The highest N-fixing and solubilization capacity identified by molecular characterization i.e latosol 4, 4.2 and alluvial 7.1, alluvial-1.11. The phylogeny analyzed the presence of bacterial isolates in two distinct groups. Latosol 3.1 and latosol 4.2 isolates clustered in the same as the genus Lysinibacillus bacteria. The Alluvial 7.1 bacterial isolate showed similarities by Fictibacillus sp. and alluvial 1.2 isolate showed similarities by the genus Bacillus sp.

This study was conducted to explore the ability of Pseudomonas fluorescens and Bacillus cereus to solubilizing a phosphate in soil for enhancing the planting growth and, its relation with soill characterization. The isolates were identified as P.fluorescens and B. cereus using convential analysis and, its phosphate solubilization ability and sidrophore was shown by the clear zone formation on National Botanical Research Institute��s Phosphate medium. Moreover, Pseudomonas fluorescens isolates (n = 9) and three of B. cereus isolated from agricultural area in Baghdad university, Mustansiriyah university and Diyala bridge. Results displayed that bacterial count were varied in soil samples according to their region, and ranging from 30 to 60 *10 2 CFU/g in Baghdad university soil to 10��20 *10 2 CFU/g in Mustansiriyah university soil, the Baghdad soil macronutrient which included: NH4, NO3, P, and K were, 8.42, 20.53, 19.09, 218.73 respectively, While the physio analysis revealed that the mean of pH was 7.3 and EC was 8.63. on the other hand the micronutrient analysis indicated that the soil samples were included Ca, Fe, Mn, Zn and Cu which gave their mean 5025.9, 8.9, 4.9, 0.5 and 1.5 respectevily. Results revealed that all isolated bacteria (9 isolates of P.fluorescens and three isolates of B. cereus gave ahalo zone which mean their ability to be phosphate solubilizing bacteria at 100%. Results revealed that all isolated bacteria were detected a ability to produce high levels from chelating agents (siderophores)) by P.fluorescens and. B cereus at 100%, when appeared ahalo clear zone. Furthermore, the high levels of phosphate solubilization and siderophore production were grouped in bacterial species isolated from Iraqi soils. might be attributed to many soil factors such as soil nutrient status, soil acidity, water content, organic matter and soil enzyme activities.
