abstract= An orange-coloured, aerobic, motile, short-rod-shaped bacterial strain, designated EGI 6500337T, was isolated from the surface-sterilized root of a halophyte, Anabasis elatior (C. A. Mey.) Schischk, collected from Urumqi, Xinjiang province, north-west China. Growth occurred at 5–35 °C (optimum 30 °C), at pH 6.0–9.0 (optimum pH 7.0) and in the presence of 0–6 % (w/v) NaCl (optimum 0–1 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain EGI 6500337T formed a distinct lineage in the cluster that comprised the genera Aurantimonas and Aureimonas in the family Aurantimonadaceae . The 16S rRNA gene sequence of strain EGI 6500337T shared highest similarity with those of Aurantimonas coralicida DSM 14790T (97.15 %) and Aurantimonas manganoxydans DSM 21871T (97.15 %). Strain EGI 6500337T contained Q-10 as the dominant isoprenoid quinone. The major cellular fatty acids were C18 : 1 ω7c and C19 : 0 ω8c cyclo. The polar lipid profile of strain EGI 6500337T contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine and phosphatidylethanolamine as major components, similarly to members of the genus Aurantimonas . The DNA G+C content of strain EGI 6500337T was 66.8 mol%. The level of DNA–DNA relatedness between strain EGI 6500337T and Aurantimonas coralicida DSM 14790T was 24.7±2.9 %. On the basis of the phylogenetic analysis, chemotaxonomic data and phenotypic characteristics, strain EGI 6500337T represents a novel species of the genus Aurantimonas , for which the name Aurantimonas endophytica sp. nov. is proposed. The type strain is EGI 6500337T (=KCTC 52296T=CPCC 100904T).,
