Abstract
A Gram-negative, facultatively anaerobic, motile, and rod-shaped bacterium, designated ASW11-47 T, was isolated from a tidal flat sediment taken from the coast of Qingdao, PR China. Phylogenetic analysis of 16S rRNA gene sequence showed that strain ASW11-47 T belongs to the genus Salinimicrobium and is most closely related to Salinimicrobium terrae YIM-C338T (98.68% similarity). The length of draft genome is 3,594,457 bp, and DNA G + C content is 40.8 mol%. The values of average nucleotide identity and digital DNA–DNA hybridization between strain ASW11-47 T and closely related strains were in ranges of 75.9–85.9 and 19.7–31.5%, respectively. The major fatty acids (> 10%) were iso-C15:0 and iso-C17:0 3-OH. The predominant respiratory quinone was menaquinone-6 and the major polar lipid was phosphatidylethanolamine. On the basis of genotypic, phenotypic, and chemotaxonomic analysis, strain ASW11-47 T represents a novel species within the genus Salinimicrobium, for which the name Salinimicrobium sediminilitoris sp. nov. is proposed. The type strain is ASW11-47 T (= KCTC 82501 T = MCCC 1K05586T).
