A Gram-stain-negative and flagellated bacterial strain, SHSM-M6T, was isolated from salt marsh from Yellow Sea, Republic of Korea. Neighbor-joining phylogenetic tree of 16S rRNA gene sequences showed that strain SHSM-M6T belongs to the genus Shewanella. 16S rRNA gene sequence similarity values between strain SHSM-M6T and the type strains of Shewanella species were <98.0%. The average nucleotide identity and DNA–DNA hybridization values between genomic sequences of strain SHSM-M6T and the type strains of Shewanella species were <73.3 and 20.7%, respectively. Strain SHSM-M6T contained MK-6 as predominant menaquinone and Q-7 and Q-8 as the predominant ubiquinones. The novel strain contained C16:1ω7c and/or C16:1ω6c, iso-C15:0 and C16:0 as major fatty acids. Major polar lipids of strain SHSM-M6T were phosphatidylethanolamine, phosphatidylglycerol, one unidentified lipid, one unidentified aminolipid and one unidentified phospholipid. Differential phenotypic properties of strain SHSM-M6T, together with its phylogenetic and genetic distinctiveness, revealed that strain SHSM-M6T is separated from recognized Shewanella species. On the basis of the data presented, strain SHSM-M6T is considered to represent a novel species of the genus Shewanella, for which the name Shewanella salipaludis sp. nov. is proposed. The type strain is SHSM-M6T (=KACC 19901T = NBRC 113646T).

Shewanella salipaludis sp。的描述 十一月。,与盐沼隔离。

革兰氏染色阴性和鞭毛细菌菌株,SHSM-M6 Ť,从盐沼从黄海,大韩民国隔离。16S rRNA基因序列的邻居连接系统树表明,SHSM-M6 T菌株属于希瓦氏菌属。SHSM-M6 T菌株与希瓦氏菌种的16S rRNA基因序列相似度<98.0%。SHSM-M6 T菌株和希瓦氏菌属类型菌株的基因组序列之间的平均核苷酸同一性和DNA-DNA杂交值分别为<73.3和20.7%。SHSM-M6 T含有MK-6作为主要的甲萘醌,Q-7和Q-8作为主要的泛醌。该新菌株含有的C 16:1个ω 7 ç和/或C 16:1个ω 6 Ç,异-C 15:0和C 16:0作为主要的脂肪酸。SHSM-M6 T菌株的主要极性脂质是磷脂酰乙醇胺,磷脂酰甘油,一种未鉴定的脂质,一种未鉴定的氨基脂质和一种未鉴定的磷脂。SHSM-M6 T菌株的差异表型特性及其系统发育和遗传特征表明,SHSM-M6 T菌株与公认的希瓦氏菌分离种类。根据提供的数据,菌株SHSM-M6 T被认为代表Shewanella属的一个新物种,其名称为Shewanella salipaludis sp。十一月 被提议。类型菌株是SHSM-M6 T(= KACC 19901 T  = NBRC 113646 T)。
