abstract= A novel strain, 22II-S11-z3T, was isolated from the deep-sea sediment of the Atlantic Ocean. The bacterium was aerobic, Gram-staining-negative, oxidase-positive and catalase-negative, oval- to rod-shaped, and non-motile. Growth was observed at salinities of 1–9 % NaCl and temperatures of 10–45 °C. The isolate could hydrolyse aesculin and Tweens 20, 40 and 80, but not gelatin. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 22II-S11-z3T belonged to the genus Aestuariivita, with highest sequence similarity to Aestuariivita boseongensis KCTC 42052T (97.5 %). The average nucleotide identity and digital DNA–DNA hybridization values between strain 22II-S11-z3T and A. boseongensis KCTC 42052T were 71.5 % and 20.0 ± 2.3 %, respectively. The G+C content of the chromosomal DNA was 65.5 mol%. The principal fatty acids (>5 %) were summed feature 8 (C18 : 1ω7c/ω6c) (35.2 %), C19 : 0 cyclo ω8c (20.9 %), C16 : 0 (11.8 %), 11-methyl C18 : 1ω7c (11.4 %) and C12 : 1 3-OH (9.4 %). The respiratory quinone was determined to be Q-10. Diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, nine unidentified phospholipids, one unidentified aminolipid and two unidentified lipids were present. The combined genotypic and phenotypic data show that strain 22II-S11-z3T represents a novel species of the genus Aestuariivita, for which the name Aestuariivita atlantica sp. nov. is proposed, with the type strain 22II-S11-z3T ( = KCTC 42276T = MCCC 1A09432T).,
