• A salt-tolerant, Gram-negative, rod-shaped and yellow-pigmented bacterium, designated strain AY-3R , was isolated from rhizosphere soil of a desert xerophyte, , sampled at Badain Jaran Desert, Alxa region, Inner Mongolia, PR China. Growth of this strain was observed at 20-42 °C (optimum, 28-30 °C), at pH 6.0-9.0 (optimum, pH 6.0-7.0) and at 0-8 % (w/v) NaCl (optimum, 3 %). Results of phylogenetic analysis based on 16S rRNA gene sequences showed that strain AY-3R was a member of the genus , with the highest similarity to Ery1 (97.6 %), followed by S3-63 (96.9 %). The predominant fatty acids (>10.0 %) were C ω7 , C ω6 and summed feature 3 (C ω7 and/or C ω6 ). The major polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid and one unknown polar lipid. The predominant respiratory quinone was ubiquinone-10. The G+C content of the genomic DNA of strain AY-3R was 66.3 mol%. On the basis of the data from this polyphasic taxonomic study, strain AY-3R represents a novel species of the genus , named sp. nov. (=MCCC 1K03572 =KCTC 72280 ).
