Özet:In the present study, the capacity of phosphate solubilizing bacterial strain, Azospirillum brasilense SP-245, Bacillus subtilis OSU-142, Bacillus megaterium M3, Raoultella terrigena, Burkholderia cepacia BA-7 have been tested solution culture containing two different rock phosphate sources. Experiment was carried out under laboratory conditions during experiment period 3 times sample was collected (10th, 20th, and 30th day). The phosphorus solubilizing bacteria inoculation decreased solution pH and increased electrical conductivity, and Ca and P concentrations in solution culture of both P source. While the largest pH decrease was found with B. cepacia BA-7, the highest EC values, Ca and P concentrations were found applications of B. megaterium M3 which has the highest acid -alkaline phosphatase enzyme activities and organic acid compound when compared to control during the 30th day of the experiment.
