A Gram-stain-negative, non-motile, non-spore-forming, rod-shaped bacterial strain, BB-Mw22T, was isolated from a tidal flat sediment of the South Sea in South Korea. It grew optimally at 30-37 °C, at pH 7.0-7.5 and in the presence of 2-3 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain BB-Mw22T belonged to the genus Kangiella and the cluster comprising Kangiella species and strain BB-Mw22T was clearly separated from other taxa. Strain BB-Mw22T exhibited 95.3-98.7 % 16S rRNA gene sequence similarity to the type strains of recognized Kangiella species. Strain BB-Mw22T contained Q-8 as the predominant ubiquionone and iso-C15:0 and iso-C11:0 3-OH as the major fatty acids. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine and one unidentified aminolipid. The DNA G+C content of strain BB-Mw22T was 48.9 mol%, and its mean DNA-DNA hybridization values with Kangiella geojedonensis YCS-5T, Kangiella japonica JCM 16211T and Kangiella taiwanensis JCM 17727T were 14-28 %. Phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain BB-Mw22T is distinguishable from all recognized Kangiella species. On the basis of the data presented, strain BB-Mw22T is considered to represent a novel species of the genus Kangiella, for which the name Kangiella sediminilitoris sp. nov. is proposed. The type strain is BB-Mw22T (= KCTC 23892T = CCUG 62217T).
