A polyphasic approach was used to investigate its taxonomic position. Strain LJ137T grew optimally at pH 7.5, at 37 °C and with 2.5 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain LJ137T was most closely related to the genera Ornithinibacillus and Oceanobacillus. The closest phylogenetic neighbours were Ornithinibacillus halophilus KCTC 13822T, Ornithinibacillus salinisoli LCB256T and Oceanobacillus limi KCTC 13823T, with 95.2, 96.5 and 95.6 % 16S rRNA gene sequence similarity, respectively. The peptidoglycan amino acid type was A4α (l-Lys–d-Asp). The major respiratory quinone was menaquinone-7 (MK-7). The polar lipids of strain LJ137T contained diphosphatidylglycerol, phosphatidylglycerol, three unidentified phospholipids, two aminophospholipids and one unidentified lipid. The G+C content of the genomic DNA was 40.4 mol%. The dominant cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C15 : 0. Based on the phenotypic, chemotaxonomic, phylogenetic and genome sequence characteristics of this strain, a novel species, Ornithinibacillus gellani sp. nov., is proposed. The type strain is LJ137T (=CGMCC 1.13678T=NBRC 113552T). An emended description of the genus Ornithinibacillus is presented. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.003500
