Strain O1T showed optimal growth at 30 °C, between pH 6.0 and 8.0, and in the presence of 1–5 % (w/v) NaCl. The predominant menaquinone was MK-8 (H2), and anteiso-C15 : 0 and anteiso-C17 : 0 were the major fatty acids. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and one unknown glycolipid. The DNA G+C content of strain O1T was 64.9 mol% and the genome size was 4.17 Mb. Based on a similarity search and phylogenetic analysis of the 16S rRNA gene sequence, strain O1T belonged to the genus Brevibacterium . The values of average nucleotide identity and in silico DNA–DNA hybridization between strain O1T and its close relatives were well below the thresholds used for the delineation of a new species. On the basis of the morphological and chemotaxonomic characteristics, as well as the genotypic data, it is proposed that strain O1T represents a novel species of the genus Brevibacterium , for which the name Brevibacterium profundi sp. nov. is proposed. The type strain is O1T (=JCM 33845T=MCCC 1A16744T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.004483
