摘要： A novel Gram-strain-negative, rod-shaped, non-flagellated, non-gliding, beige-pigmented and aerobic bacterium, designated strain UJN715(T), was isolated from rhizosphere soil of Alhagi sparsifolia obtained from Alear city, located in Xinjiang province, PR China. Growth optimally occurred at 37 degrees C, pH 6.5-7.5, and 0-3% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain UJN715(T) belonged to the genus Chelativorans, with the highest sequence similarity to Chelativorans multitrophicus DSM 9103( T) (97.7%). Genome sequencing revealed a genome size of 5 702 301 bp and a G + C content of 64.1 mol%. The ANI, POCP and the dDDH between strain UJN715(T) and C. multitrophicus DSM 9103( T) were 76.2%, 49.3%, and 20.5%, respectively. The prediction result of secondary metabolites based on genome showed that the strain UJN715(T) contained one cluster of ectoine production, one cluster of non-ribosomal peptide synthetase (NRPS), one cluster of type I polyketide synthases (TIPKS), one cluster of bacteriocin, one cluster of TfuA-related, one cluster of N-acetylglutaminylglutamine amide (NAGGN) production, one cluster of terpene production, two clusters of homoserine lactone (Hserlactone) production. The major respiratory quinone was Q-10. The major fatty acids were iso-C-17:0, C-18:0 and C-19:0 cyclo omega 8c and its polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, phospholipids, unknown lipids, diphosphatidylglycerol, aminoglycolipid, unidentified aminophospholipids. On the basis of these data, strain UJN715(T) is considered to represent a novel species of the genus Chelativorans, for which the name Chelativorans alearense sp. nov. is proposed. The type strain is UJN715(T) (= KCTC 72856(T) = CCTCC AB2019378(T)).
