A Gram-negative, non-motile, non-endospore-forming bacterial strain, designated DPSR-4T, was isolated from a tidal flat sediment on the southern coast of Korea. Strain DPSR-4T grew optimally at 25–30°C, at pH 7.0–7.5 and in the presence of 2% (w/v) NaCl. A Neighbour-Joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain DPSR-4T clustered with Salinimonaschungwhensis BH030046T by a high bootstrap resampling value of 99.7%. Strain DPSR-4T exhibited 96.2% 16S rRNA gene sequence similarity to that of S. chungwhensis BH030046T and 93.7–96.6% sequence similarity to the sequences of type strains of Alteromonas species. Strain DPSR-4T contained Q-8 as the predominant ubiquinone and iso-C15:0 2-OH and/or C16:1ω7c, C16:0 and C18:1ω7c as the major fatty acids. The major polar lipids detected in strain DPSR-4T and S. chungwhensis KCTC 12239T were phosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The DNA G+C content was 53.4 mol%. Differential phenotypic properties and phylogenetic distinctiveness of strain DPSR-4T demonstrated that this strain is distinguishable from the sole recognized species of the genus Salinimonas, S. chungwhensis. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain DPSR-4T is considered to represent a novel species of the genus Salinimonas, for which the name Salinimonas lutimaris sp. nov. is proposed. The type strain is DPSR-4T (KCTC 23464T, CCUG 60743T).
