A Gram-negative, non-motile and rod-shaped bacterial strain, ISL-46(T), belonging to the Alphaproteobacteria, was isolated from a marine solar saltern in Korea, and subjected to a polyphasic taxonomic study. Strain ISL-46(T) grew optimally at pH 7.0-8.0 and 30 degrees C and in the presence of 7 % (w/v) NaCl. It contained Q-10 as the predominant ubiquinone and C(19 : 0) cyclo omega8c, C(18 : 1)omega7c and 11-methyl C(18 : 1)omega7c as the major fatty acids. The DNA G+C content was 63.5 mol%. Strain ISL-46(T) exhibited 16S rRNA gene sequence similarity values of 94.1-95.3 % to members of the phylogenetically related genera Roseivivax, Salipiger, Citreicella, Yangia and Citreimonas. Strain ISL-46(T) could be differentiated from the above-mentioned genera by differences in compositions of the major fatty acids and in some phenotypic properties. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain ISL-46(T) is considered to represent a novel genus and species, for which the name Salinihabitans flavidus gen. nov., sp. nov. is proposed. The type strain is ISL-46(T) (=KCTC 22485(T)=CCUG 56758(T)).
从韩国一处海洋太阳能盐场分离出一株革兰氏阴性、无运动性的杆状细菌菌株ISL-46(T)，该菌株属于α-变形菌纲，并对其进行了多相分类研究。菌株ISL-46(T)在pH 7.0 - 8.0、30℃以及7%（w/v）NaCl存在的条件下生长最佳。它以Q-10作为主要泛醌，以C(19 : 0)环ω8c、C(18 : 1)ω7c和11-甲基C(18 : 1)ω7c作为主要脂肪酸。DNA G+C含量为63.5 mol%。菌株ISL-46(T)与系统发育相关的玫瑰色游动菌属、盐栖菌属、柠檬黄菌属、扬氏菌属和柠檬单胞菌属成员的16S rRNA基因序列相似性值为94.1 - 95.3%。菌株ISL-46(T)可通过主要脂肪酸组成和一些表型特征的差异与上述属区分开来。基于表型、化学分类和系统发育数据，菌株ISL-46(T)被认为代表一个新的属和种，为此提出新属名盐栖菌属（Salinihabitans）、新种名淡黄盐栖菌（Salinihabitans flavidus）。模式菌株为ISL-46(T)（=KCTC 22485(T)=CCUG 56758(T)）。
