A Gram-strain-negative, rod-shaped, aerobic bacterium, designated 216_PA32_1T, was isolated from deep-sea sediment of the Pacific Ocean. Cells of strain 216_PA32_1T were non-motile, oxidase-positive and catalase-negative. The strain could grow at temperatures of 10–45 °C (optimum, 32–35 °C), at pH 5.0–10.0 (optimum, 6.0–7.0) and at salinities of 0–10% (optimum, 2–8%). The principal fatty acid (>10 %) was summed feature 8 (C18:1 ω6c/ω7c). The sole respiratory quinone was Q10 (100 %). The polar lipids included phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, two unidentified phospholipids and five unidentified aminolipids. The G+C content of the chromosomal DNA was 66.3 mol%. According to the 16S rRNA gene similarity, strain 216_PA32_1T showed the highest sequence similarity to Pseudooceanicola nitratireducens JLT 1210T (97.3 %), followed by Pseudooceanicola nanhaiensis SS011B1-20T (97.1 %). Phylogenetic trees indicated that strain 216_PA32_1T clustered with strain P. nanhaiensis SS011B1-20T. The average nucleotide identity and the DNA–DNA hybridization values between strain 216_PA32_1T and all species of the genus Pseudooceanicola were below 79.5 and 20.6%, respectively. A combination of the phylogenetic, phenotypic, chemotaxonomic and genomic evidence demonstrated that strain 216_PA32_1T represents a novel species of the genus Pseudooceanicola , for which the name Pseudooceanicola pacificus sp. nov. is proposed. The type strain is 216_PA32_1T (=MCCC 1A14128T=KCTC 72688T).

A novel Gram-stain-negative, facultatively anaerobic, rod-shaped bacterium, designated as D167-6-1T, was isolated from deep-sea sediment collected from the Pacific Ocean. The cells were catalase- and oxidase-positive, and motile by means of peritrichous flagella. Growth occurred at NaCl concentrations ranging from 0 to 19 % (optimum, 2–8 %, w/v), from pH 6 to 11 (optimum, 7–8) and at temperatures between 4 and 45 °C (optimum, 33 °C). Phylogenetic analysis based on 16S rRNA, gyrB and rpoD gene sequences and its genome sequence revealed that strain D167-6-1T formed a monophyletic branch within the genus Halomonas and was most closely related to Halomonas saliphila , Halomonas pellis , Halomonas kenyensis , Halomonas daqingensis , Halomonas desiderata and Halomonas lactosivorans (with 98.5, 98.5, 98.4, 98.1, 97.5 and 97.8 % 16S rRNA sequence similarity, respectively). The complete genome size of strain D167-6-1T was 4.49 Mb, with a DNA G+C content of 62.8 mol%. The estimated averagenucleotide identity and DNA–DNA hybridization values between strain D167-6-1T and other closely related species were 77.59–85.35 % and 22.0–30.6 %, respectively. The principal cellular fatty acids (>5 %) were C18 : 1  ω7c, C16 : 0, C19 : 0 cyclo ω8c, summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c) and C17 : 0 cyclo. The polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, an unidentified aminolipid, aminophospholipid and two unidentified phospholipids. The predominant respiratory quinones were Q-9 and Q-8. The combined genotypic and phenotypic data show that strain D167-6-1T represents a novel species of the genus Halomonas , for which the name Halomonas diversa sp. nov. is proposed, with the type strain D167-6-1T (=MCCC 1A13316T=KCTC 72441T).

A new Gram-stain-positive, aerobic, non-motile and rod-shaped actinobacterium, designated O1T, was isolated from a deep-sea sediment of the Western Pacific Ocean. 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).
