The isolates were strictly aerobic, spore-forming, Gram-positive rods. They grew optimally in the presence of 20–26 % NaCl. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The predominant menaquinone was MK-7. The major cellular fatty acids were anteiso-C15 : 0 and anteiso-C17 : 0. Polar lipid analysis revealed the presence of phosphatidylglycerol, diphosphatidylglycerol and two unidentified glycolipids. The DNA G+C content was 42.1–43.1 mol%. On the basis of the 16S rRNA gene sequence, a representative strain, PS11-2T, was found to be closely related to Lentibacillus juripiscarius JCM 12147T (97.3 % similarity). The 15 strains were included in the same species on the basis that the levels of DNA–DNA relatedness with strain PS11-2T were greater than 70 %. They could be distinguished from L. juripiscarius and other Lentibacillus species on the basis of several phenotypic characteristics and low levels of DNA–DNA relatedness (⩽19.4 %). Therefore, the strains represent a novel species of the genus Lentibacillus, for which the name Lentibacillus halophilus sp. nov. is proposed. The type strain is PS11-2T (=JCM 12149T=TISTR 1549T=PCU 240T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.63997-0
