  • Descrição: Light yellowish-white colonies of a bacterial strain, designated LNNU 24178 T , were isolated from the rhizosphere soil of halophyte Suaeda aralocaspica (Bunge) Freitag and Schütze grown at Shihezi district, Xinjiang, PR China. Cells were Gram-stain-negative, non-flagellum-forming, rod-shaped and non-motile. The results of phylogenetic analysis based on the 16S rRNA gene sequence indicated that LNNU 24178 T represented a member of the genus Luteimonas and shared the highest sequence similarity with Luteimonas yindakuii CGMCC 1.13927 T (97.1 %) and lower sequence similarity (< 97.0 %) to other known species. The genomic DNA G+C content of LNNU 24178 T was 68.8 %. The average nucleotide identity (ANI) values between LNNU 24178 T and Luteimonas yindakuii CGMCC 1.13927 T , Luteimonas mephitis DSM 12574 T , Luteimonas arsenica 26-35 T and Luteimonas huabeiensis HB2 T were 78.7, 78.6, 78.4 and 80.0 %, respectively. The digital DNA–DNA hybridisation (dDDH) values between LNNU 24178 T and L. yindakuii CGMCC 1.13927 T , L. mephitis DSM 12574 T , L. arsenica 26-35 T and L. huabeiensis HB2 T were 22.0, 22.3, 22.2 and 23.5 %, respectively. The respiratory quinone detected in LNNU 24178 T was ubiquinone-8 (Q-8). The major fatty acids (> 5.0 %) of LNNU 24178 T were identified as iso-C 15 : 0 (33.9 %), iso-C 17 : 0 (8.7 %), iso-C 11 : 0 (6.2 %), iso-C 16 : 0 (5.7 %), C 16 : 0 (5.3 %) and summed feature 9 (iso-C 17 : 1 ω9 c /10-methyl C 16 : 0 ) (21.1 %). The major polar lipids of LNNU 24178 T were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylethanolamine (PE), one unidentified phospholipid (PL), one unidentified glycolipid (GL) and three unidentified lipids. According to the data obtained from phenotypic, chemotaxonomic and phylogenetic analyses, strain LNNU 24178 T represents a novel species of the genus Luteimonas , for which the name Luteimonas suaedae sp. nov. is proposed, with LNNU 24178 T (= CGMCC 1.17331 T = KCTC 62251 T ) as the type strain.
