“…The predominant isoprenoid quinone detected in strain BSSL-BM11 T was ubiquinone-10 (Q-10; approx. 92 %), which is typical of the majority of the class Alphaproteobacteria as well as the genera Tianweitania and Corticibacterium [1, 2]; a minor amount of Q-9 (approx. 7 %) was also present.…”

“…Comparative 16S rRNA gene sequence analysis showed that this novel strain is phylogenetically affiliated with members of the family Alphaproteobacteria but its exact taxonomic status is not clear due to similar 16S rRNA gene sequence similarities to members of the genera Tianweitania and Corticibacterium. These two genera were published in the same volume of the International Journal of Systematic and Evolutionary Microbiology, only few pages apart, and not compared [1,2]. The genus Tianweitania was proposed by Han et al [1] with the description of a single species with a validly published name, Tianweitania sediminis, which was isolated from subsurface sediment in north-east China.…”

A Gram-stain-negative, aerobic, non-flagellated and coccoid or ovoid bacterial strain, BSSL-BM11T, was isolated from sand of coastal dunes along the Yellow Sea of the Korean peninsula. Strain BSSL-BM11T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0–3.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences, the up-to-date bacterial core gene set and average amino acid identity (AAI) showed that strain BSSL-BM11T forms a cluster with the type strains of Tianweitania sediminis and Corticibacterium populi . Strain BSSL-BM11T showed 16S rRNA gene sequence similarities of 98.3 and 98.0 % to the type strains of T. sediminis and C. populi , respectively, and less than 96.4 % to the type strains of the other recognized species. The average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values between strain BSSL-BM11T and the type strains of T. sediminis and C. populi were 77.0–84.8 % and 20.0–28.1 %, respectively. The 16S rRNA gene similarity, AAI, ANI and dDDH values between T. sediminis Z8T and C. populi KCTC 42249T were 98.0, 77.4, 76.7 and 20.1 %, respectively. The DNA G+C content of strain BSSL-BM11T from genomic sequence data was 61.3 mol%. Strain BSSL-BM11T contained Q-10 as the predominant ubiquinone and C18 : 1 ω7c, C16 : 0 and cyclo C19 : 0 ω8c as the major fatty acids. The major polar lipids of strain BSSL-BM11T were phosphatidylcholine, phosphatidylglycerol and phosphatidylethanolamine. Based on the polyphasic data, it is proposed that C, populi be reclassified as a member of the genus Tianweitania . Phenotypic and phylogenetic analyses revealed that strain BSSL-BM11T is separated from T. sediminis and C. populi . On the basis of the data presented here, strain BSSL-BM11T (=KACC 21634T=NBRC 114503T) is considered to represent a novel species of the genus Tianweitania , for which the name Tianweitania aestuarii sp. nov. is proposed.
