A taxonomic study was carried out on strain 22II14-10F7T,which was isolated from the deep sea water of the Atlantic Ocean with oil-degrading enrichment.The bacterium was Gram-negative,oxidase-and catalase-positive,rod-shape.Growth was observed at salinities from 0.5 to 15%and at temperatures from 4 to 37 ℃,it was unable to hydrolyze Tween 40,80 or gelatin.Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 22Ⅱ14-10F7T belonged to the genus Zunongwangia,with highest sequence similarity of 97.3%to Zunongwangia profunda SM-A87T,while the others were all below 94.0%.The DDH estimate value between strain 22Ⅱ14-10F7T and Z.profunda SM-A87T was 27.20%±2.43%according to their genome sequences.The principal fatty acids were iso-C15:0 (22.42%),C15:0 anteiso (8.90%),iso-C15:1G (8.50%),iso-C17:0 3OH (12.78%),Sum In Feature 3 (C16:1ω7c /ω6c) (8.09%) and Sum In Feature 9 (iso-C17:1ω9c or C16:0 10-methyl) (13.54%).The G+C content of the chromosomal DNA was 35.5 mol%.The major respiratory quinone was determined to be MK-6.Phosphatidylethanolamine (PE),two aminolipids (AL1 and AL2) and five unknown lipids (L1-L5) were present.The combined genotypic and phenotypic data show that strain 22Ⅱ14-10F7T represents a novel species of the genus Zunongwangia,for which the name Zunongwangia atlantica sp.nov.is proposed,with the type strain 22Ⅱ14-10F7T (=CGMCC1.12470T =LMG 27421T=MCCC 1A06481T).
