| Abstract: | A plant growth promoting bacterial isolate (D5/23T) from the phyllosphere of winter wheat, able to fix atmospheric nitrogen and to produce auxines and cytokinins was investigated in a polyphasic taxonomy approach. Phylogenetic analyses using the 16S rRNA gene sequence of the strain clearly indicated that the strain belonged to the family Enterobacteriaceae, most closely related to Enterobacter cloacae with 99.0% and Enterobacter dissolvens with 98.5% sequence similarity. Phylogenetic analysis derived from the sequence of the rpoB gene showed the highest sequence similarities to Enterobacter cowanii (93.0%) but supported the distinct position of strain D5/23T. The isolate produced a fatty acid pattern typical for members of the family Enterobacteriaceae. On the basis of the phylogenetic analyses, DNA-DNA hybridizations, and the unique physiological and biochemical characteristics, we propose that strain D5/23T represents a new species of the genus Enterobacter for which we propose the name Enterobacter radicincitans sp. nov. |
