A Gram-stain-negative, aerobic, rod-shaped, non-gliding and non-motile bacterium designated as N1E253T, was isolated from marine sediments collected from the coast of Weihai, PR China. N1E253T was found to grow at pH 7.0–9.0 (optimum, pH 7.5), 15–37 °C (optimum, 30 °C) in the presence of 1.5–5.0% (w/v) NaCl (optimum, 3.0%). The major polar lipids of strain N1E253T were phosphatidylethanolamine, diphosphatidylglycerol and one unidentified phospholipid. The sole respiratory quinone was MK-9. The major cellular fatty acids (> 10.0%) were iso-C14: 0, C16: 0 and Summed Feature 3 (C16:1 ω7c and/or C16:1 ω6c). The result of the 16S rRNA gene sequence analysis confirmed the affiliation of this novel isolate to the family Verrucomicrobiaceae, with Persicirhabdus sediminis KCTC 22039 T being its closest relative with 92.1% sequence similarity. Genome sequencing revealed a genome size of 5,073,947 bp, DNA G + C content of 52.0% and two protein-coding genes related to the resistance of fluoroquinolones. Based on physiological, genomic, biochemical and chemotaxonomic characteristics, we propose that strain N1E253T represents a novel species of a novel genus within the family Verrucomicrobiaceae, for which the name Oceaniferula marina gen. nov., sp. nov. is proposed. The type strain is N1E253T (= KCTC 72800 T = MCCC 1H00405T).
