A Gram-stain-negative, non-motile, rod-shaped, strictly aerobic bacterial strain, designated CAU 1289T, was isolated from a marine sand and its taxonomic position was investigated using a polyphasic approach. It grew optimally at pH 6.5 and 30 °C and in the presence of 3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CAU 1289T belonged to the genus
Salegentibacter
, exhibiting sequence similarity values of 93.6–96.3 % to members of this genus, and was related most closely to
Salegentibacter mishustinae
KMM 6049T (96.3 % similarity). Strain CAU 1289T contained MK-6 as the predominant menaquinone. The major fatty acid was iso-C15 : 0. The cell-wall peptidoglycan of strain CAU 1289T contained meso-diaminopimelic acid. The polar lipids were composed of phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylcholine, an unidentified phospholipid, an unidentified aminolipid, an unidentified aminophospholipid, an unidentified glycolipid and ten unidentified lipids. The DNA G+C content was 38.7 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic inference, strain CAU 1289T is considered to represent a novel species of the genus
Salegentibacter
, for which the name Salegentibacter chungangensis sp. nov. is proposed. The type strain is CAU 1289T (KCTC 24000T = CCUG 64793T). An emended description of the genus
Salegentibacter
is also proposed.
