Abstract

A Gram-stain-negative, strictly aerobic, non-motile, cream, long rod-shaped bacterium, designated strain ZL136, was isolated from deep water of the South China Sea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that this strain belonged to the genus with highest sequence similarity to OCh 239 (97.0 %), followed by sw-2 (96.9 %). Growth occurred at 4–37 °C (optimum 32 °C), pH 6.0–10.0 (optimum 8.0) and in the presence of 0–12 % (w/v) NaCl (optimum 3–4 %) in marine broth 2216. Strain ZL136 did not produce bacteriochlorophyll . The predominant fatty acids were Cω7 and/or Cω6, C, C and 11-methyl Cω7. The major polar lipids of ZL136 were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unidentified lipid. The major respiratory quinone was ubiquinone Q-10. The genomic DNA G+C content of strain ZL136 was 67.0 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic analysis, strain ZL136 was classified as a representative of a novel species in the genus of , for which the name sp. nov. is proposed. The type strain is ZL136 ( = JCM 19386 = KCTC 32470).
