Özet

In this study; Soil samples were taken from 15 different areas in the Kuruçalı microcatchment 

and brought to the laboratory in a vehicle refrigerator at +4 ℃. A total of 85 different bacterial strains were 

obtained in different numbers from each of these soil samples. Phosphate solubility, nitrogen fixation and 

siderephore production tests were carried out to determine the plant growth-promoting properties of all the 

bacteria obtained. According to the results obtained; In the nitrogen fixation test, 25 bacteria gave strong 

positive results, 8 bacteria gave weak positive results, and 52 bacteria gave negative results. Among all bacteria, 

5 bacterial strains gave positive results in phosphate solvent tests and the others gave negative results. As a 

result of the siderophore tests, 17 bacterial strains gave positive results. According to all the results obtained, 

it is thought that strains that are positive in terms of all three features may be potential PGPB.
