A Gram-positive, motile, moderately halophilic and rod-shaped bacterium, strain AHS-1T, was isolated from a marine solar saltern in Korea, and its exact taxonomic position was investigated by use of a polyphasic study. Strain AHS-1T grew optimally at pH 6.5-7.0 and 37-40 °C in the presence of 10-12 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain AHS-1T belonged to the genus Lentibacillus. Strain AHS-1T exhibited a 16S rRNA gene sequence similarity value of 97.0% to the type strain of Lentibacillus salarius and values of 95.0-96.7 % to the type strains of other recognized Lentibacillus species. Strain AHS-1T had cell-wall peptidoglycan based on meso-diaminopimelic acid. It contained MK-7 as the predominant menaquinone. The major fatty acids (>10% of total fatty acids) were anteiso-C15:0 and anteiso-C17:0, and the major polar lipids were phosphatidylglycerol, diphosphatidylglycerol and two unidentified glycolipids. The DNA G + C content was 49.0 mol%. Strain AHS-1T shared a mean level of DNA-DNA relatedness of 8.5% with L. salarius KCTC 3911T. Strain AHS-1T could also be distinguished from recognized Lentibacillus species based on several phenotypic properties. On the basis of phenotypic, chemotaxonomic, phylogenetic and genetic data, strain AHS-1T is considered to represent a novel species of the genus Lentibacillus, for which the name Lentibacillus salinarum sp. nov. is proposed. The type strain is AHS-1T (=KCTC 13162T= CCUG 54822T).
