【摘要】:A taxonomic study was carried out on strain 22II14-10F7 T, 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 °C, it was unable to hydrolyze Tween 40, 80 or gelatin. Phylogenetic analysis based on 16 S r RNA gene sequences indicated that strain 22II14-10F7 T belonged to the genus Zunongwangia, with highest sequence similarity of 97.3 % to Zunongwangia profunda SM-A87 T, while the others were all below 94.0 %. The DDH estimate value between strain 22II14-10F7 T and Z. profunda SM-A87 T 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 22II14-10F7 T represents a novel species of the genus Zunongwangia, for which the name Zunongwangia atlantica sp. nov. is proposed, with the type strain 22II14-10F7T(=CGMCC1.12470 T =LMG 27421T=MCCC 1A06481T).
