A Gram-negative, motile, oxidase- and catalase-positive and facultatively aerobic bacterium, designated S3-22T, was isolated from marine sediment of the Nella Fjord, Antarctica. Strain S3-22T reduced nitrate to nitrite and grew at pH 6.0–8.0, at 4–25 °C and with 0.5–5 % (w/v) NaCl. It contained Q-8 as the only respiratory quinone and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH), C16 : 0 and C18 : 1 ω7c as the major cellular fatty acids. The genomic DNA G+C content was 45.6 mol%. Phylogenetic analyses of 16S rRNA gene sequences showed that strain S3-22T was affiliated with the genus Neptunomonas, with 97.1 % sequence similarity to Neptunomonas japonica JAMM 0745T and 94.8 % to Neptunomonas naphthovorans NAG-2N-126T, the type strains of the only two recognized Neptunomonas species. DNA–DNA relatedness between strain S3-22T and N. japonica JCM 14595T was 20.4 %. Strain S3-22T could be distinguished from the type strains of Neptunomonas species by several phenotypic properties. Based on the evidence from our polyphasic study, strain S3-22T represents a novel Neptunomonas species, for which the name Neptunomonas antarctica sp. nov. is proposed. The type strain is S3-22T (=CCTCC AB 209086T =KACC 14056T).

A Gram-variable, motile, endospore-forming, slightly halophilic bacterial strain, DSW-10T, was isolated from Dokdo, an island located at the edge of the East Sea, Korea, and was characterized taxonomically by using a polyphasic approach. This isolate grew optimally at 37 °C and in the presence of 4–5 % NaCl. Strain DSW-10T had cell-wall peptidoglycan based on meso-diaminopimelic acid, MK-7 as the predominant menaquinone, and anteiso-C15 : 0, iso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0 as major fatty acids. Major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and unidentified phospholipids. The DNA G+C content was 36·7 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DSW-10T is phylogenetically affiliated to the genus Virgibacillus, and exhibited sequence similarity of 95·3–98·7 % to the type strains of Virgibacillus species.
