Identification of bacteria isolated from plants taken from pifferent prouinces and determination of properties of nitrogen fixation, phosphorus, potassium and calci̇um solubilizing

In this study, 23 healthy plant samples were taken from different provinces. 246 bacterial strains were isolated from the plants. Bacterial strains were tested for hypersensitive response (HR) on tobacco. HR test showed that bacterial strains were not pathogenic. The strains were identified by using the Microbial Identification System. According to the fatty acid methyl ester analysis results bacterial strains were determined as follow; Arthbacter (17), Brevibacillus (12), Bacillus (65), Lysinibacillus (3), Herbaspirillum (7), Kocuria (21), Paucimonas (8), Pseudomonas (36), Virgibacillus (3), Microbacterium (11), Micrococcus (8), Erwinia (4), Stenotrophomonas (8), Nesterenkonia (1), Achromobacter (1), Curtobacterium (5), Rhodococcus (7), Enterobacter (2), Escherichia (1), Chryseobacterium (1), Xanthomonas (3), Acinetobacter (5), Rothia (1), Paenibacillus (1), Ochrobacterium (1), Pantoea (1), Sphingbacterium (5), Rhizobium (3), Grimontia (1), Aeromonas (1) , Brevundimonas (1), Phyllobacterium (1) ve Staphylococcus (1). The obtained bacterial strains were tested for nitrogen fixing, phosphate, potassium and calcium solubilising properties. Herbaspirillum huttiense (SK4, SK49), Microbacterium esteraromaticum (SK19, SK39, SY48), Achromobacter xylosoxidans (SK50), Paucimonas lemoignei (SK56), Pantoea agglomerans (SY43) , Pseudomonas putida biotype B (YS2, DT17), Pseudomonas syringae pv. syringae (EP19), Pseudomonas pseudoalcaligenes (SA20) strains were found to be positive in all tests and the test results of other strains were found to be variable. Key Words: MIS, Phosphate solubilizing bacteria, Potassium solubilizing bacteria, Calcium solubilizing bacteria, Nitrogen fixation
