Detection of local Plant Growth Promoting Bacteria from wheat rhizosphere and identification of a promising isolate belonging to Enterobacter hormaechei

Abstract

This research aimed to isolate Plant Growth Promoting Bacteria from wheat rhizosphere from several regions in Syria . A total of 44 bacterial isolates isolated from the rhizosphere region of wheat plants were studied for their ability to enhance plant growth. The results showed that 16 of the isolates were able to fix atmospheric nitrogen, 19 of them were positive for phosphate solubilization, while 21 were potassium solubilizers. As for indole acetic acid production, only 15 of the isolates were able to produce it. The test results showed that the best isolate has been coded SY-Ba 16.2 and as a result of biochemical and molecular analysis and phylogenetic tree, it was found to belong to the bacterial species Enterobacter hormaechei.
