A taxonomic study was performed on strain QM42(T), which was isolated from coastal seawater from an aquaculture site near Qingdao, China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain QM42(T) was a member of the class Gammaproteobacteria. Cells of strain QM42(T) were Gram-negative, yellow, aerobic and rod-shaped. The strain formed a distinct phyletic line with less than 91 % 16S rRNA gene sequence similarity to its closest relatives with validly published names within the class Gammaproteobacteria. The genomic DNA G+C content was 51.9 mol%. The major fatty acids were C(16 : 1)omega7c/iso-C(15 : 0) 2-OH, C(18 : 1)omega7c and C(16 : 0). Based on data from a polyphasic chemotaxonomic, physiological and biochemical study, strain QM42(T) is considered to represent a novel genus and species, for which the name Gilvimarinus chinensis gen. nov., sp. nov., is proposed. The type strain is QM42(T) (=CGMCC 1.7008(T)=DSM 19667(T)).
对来自中国青岛附近水产养殖区沿海海水的菌株 QM42(T) 进行了分类学研究。基于 16S rRNA 基因序列的系统发育分析表明，菌株 QM42(T) 是γ变形菌纲的成员。细胞呈革兰氏阴性、黄色、需氧和杆状。该菌株与γ变形菌纲中具有有效发表名称的最接近的亲缘关系菌株的 16S rRNA 基因序列相似性小于 91%，形成了一个独特的分支。基因组 DNA G+C 含量为 51.9 mol%。主要脂肪酸为 C(16:1)ω7c/iso-C(15:0)2-OH、C(18:1)ω7c 和 C(16:0)。根据多相化学分类学、生理和生化研究的数据，菌株 QM42(T) 被认为代表了一个新的属和种，因此建议使用新的属名和种名 Gilvimarinus chinensis gen. nov.，sp. nov.。模式菌株为 QM42(T)=CGMCC 1.7008=DSM 19667(T)。
