从青岛沿海表层海水中分离到两株革兰氏阴性菌SM1969T和SM1979T。通过系统发育、基因组学、化学分类和表型分析对其进行了分类鉴定。两株菌株的16S rRNA基因序列相似性为97.0%，与红杆菌科玫瑰杆菌群中Shimia属、Tritonibacter属和Tropicibacter属6种类型菌株的相似性最高（96.8-97.5%）。在基于单拷贝同源簇（OCs）的系统发育树中，这两个菌株与已知的Tritonibacter属物种聚集在一起，共同形成了一个与Tritonibacter ulvae相邻的单独分支。尽管这两个菌株具有许多化学分类和表型特征，但它们可以通过许多性状相互区分，并与密切相关的物种区分开来。特别是菌株SM1969T在其基因组中发现DMSP裂解酶编码基因dddW，具有从DMSP生产DMS的能力，而菌株SM1979T则没有。为这两个新种命名为水毛三杆菌（tritonbacter aquimaris sp. 11）和lititonbacter litoralis sp. 11，类型菌株分别为SM1969T （= MCCC 1K04320T = KCTC 72843T）和SM1979T （= MCCC 1K04321T = KCTC 72842T）。
Two Gram-stain-negative bacterial strains, SM1969T and SM1979T, were isolated from coastal surface seawater of Qingdao, China. They were taxonomically characterized by the phylogenetic, genomic, chemotaxonomic and phenotypic analyses. The two strains shared 97.0% 16S rRNA gene sequence similarity with each other and the highest similarity (96.8–97.5%) with type strains of six species in the genera Shimia, Tritonibacter and Tropicibacter in the Roseobacter group of the family Rhodobacteraceae. In the phylogenetic tree based on single-copy orthologous clusters (OCs), both strains clustered with known species of the genus Tritonibacter and together formed a separate branch adjacent to Tritonibacter ulvae. Although sharing many chemotaxonomic and phenotypic characteristics, the two strains could be differentiated from each other and closely related species by numerous traits. Particularly, strain SM1969T was found to have a DMSP lyase coding gene dddW in its genome and have the ability to produce DMS from DMSP while strain SM1979T was not. The names Tritonibacter aquimaris sp. nov. and Tritonibacter litoralis sp. nov. are proposed for the two new species, with type strains being SM1969T (= MCCC 1K04320T = KCTC 72843T) and SM1979T (= MCCC 1K04321T = KCTC 72842T), respectively.
