The genus Thalassotalea is ubiquitous in marine environments, and up to 20 species have been described so far. A Gram-staining-negative, aerobic bacterium, designated strain PTE2T was isolated from laboratory-reared larvae of the Japanese sea cucumber Apostichopus japonicus. Phylogenetic analysis based on the 16S rRNA gene nucleotide sequences revealed that PTE2T was closely related to Thalassotalea sediminis N211T (= KCTC 42588T = MCCC 1H00116T) with 97.9% sequence similarity. ANI and in silico DDH values against Thalassotalea species were 68.5-77.0% and 19.7-24.6%, respectively, indicating the novelty of PTE2T. Based on genome-based taxonomic approaches, strain PTE2T (= JCM 34608T = KCTC 82592T) is proposed as a new species, Thalassotalea hakodatensis sp. nov.
塔氏菌属普遍存在于海洋环境中，迄今为止已描述了 20 个种。一株革兰氏阴性、需氧细菌，命名为 PTE2T 菌株，从人工养殖的日本刺参（Apostichopus japonicus）幼体中分离得到。基于 16S rRNA 基因核苷酸序列的系统发育分析表明，PTE2T 与 Sediminibacterium sediminis N211T（= KCTC 42588T = MCCC 1H00116T）密切相关，相似度为 97.9%。ANI 和基于基因组的 DDH 值与 Thalassotalea 属的物种分别为 68.5-77.0%和 19.7-24.6%，表明 PTE2T 的新颖性。基于基于基因组的分类方法，菌株 PTE2T（= JCM 34608T = KCTC 82592T）被提议为一个新种，即 Hakodatensis 塔氏菌（Thalassotalea hakodatensis）sp. nov.
