An aerobic, Gram-negative, non-motile, non-spore-forming, rod-shaped, and pale yellow-colored bacterial strain, designated TS118^T, was isolated from a sand sample obtained from a coastal sand dune after exposure to 3 kGy of gamma radiation. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate was a member of the genus Spirosoma and most closely related to Spirosoma metallicum PR1014k^T (95.1% similarity). The genome of strain TS118^T is constituted by one chromosome (5,691,492 bp) and one plasmid (28,440 bp) and has a G + C content of 52.7%. The genome contains 4641 protein coding sequences (CDSs), 38 tRNAs, and 11 rRNAs. The predominant fatty acids of strain TS118^T were C_16:1 ω5c, iso-C_15:0, C_16:0, summed feature 3 (C_16:1 ω6c and/or C_16:1 ω7c), and iso-C_17:0 3-OH. The major polar lipids were phosphatidylethanolamine, an unidentified amino lipid and an unidentified aminophospholipid. The main respiratory quinone was menaquinone-7 (MK-7). The novel strain showed resistance to gamma radiation with a D₁₀ value (i.e., the dose required to reduce the bacterial population by tenfold) of 4.3 kGy. Based on the phylogenetic, physiological, and chemotaxonomic characteristics, strain TS118^T represents a novel species, for which the name Spirosoma taeanense sp. nov. is proposed. The type strain is TS118^T (=KCTC 72898^T =JCM 34024^T).

在暴露于 3 kGy 的沿海沙丘的沙样中分离出一种需氧、革兰氏阴性、不运动、不形成孢子、杆状和淡黄色的细菌菌株，命名为 TS118 ^T伽马辐射。基于 16S rRNA 基因序列的系统发育分析表明，该分离物是Spirosoma属的成员，与Spirosoma metalum PR1014k ^T最密切相关（95.1% 相似性）。TS118 ^T菌株的基因组由一条染色体 (5,691,492 bp) 和一个质粒 (28,440 bp) 组成，G + C 含量为 52.7%。基因组包含 4641 个蛋白质编码序列 (CDS)、38 个 tRNA 和 11 个 rRNA。菌株 TS118 ^T的主要脂肪酸是 C _16:1 ω 5 c、iso-C _15:0、C _16:0、总特征 3（C _16:1 ω 6 c和/或 C _16:1 ω 7 c）和 iso-C _{17： 0} 3-OH。主要的极性脂质是磷脂酰乙醇胺、一种未鉴定的氨基脂质和一种未鉴定的氨基磷脂。主要的呼吸醌是甲基萘醌-7 (MK-7)。新菌株显示出对伽马辐射的抗性，D ₁₀值（即，将细菌数量减少十倍所需的剂量）为 4.3 kGy。根据系统发育、生理和化学分类学特征，菌株 TS118 ^T代表一个新物种，名称为Spirosoma taeanense sp。十一月 被提议。类型菌株是 TS118 ^T (=KCTC 72898 ^T = JCM 34024 ^T )。
