sp. nov. isolated from deep-sea water Free

Abstract

A Gram-stain-negative, strictly aerobic, non-motile, rod-shaped bacterial strain, designated strain DSW4-44, was isolated from deep-sea water from the East Sea of Korea. The optimum temperature and pH for growth were 25 °C and pH 7.5. DSW4-44 grew with 1.0–6.0 % NaCl, having optimum growth at 3–4 %. Phylogenetic analyses based on 16S rRNA gene sequences indicated that DSW4-44 represented a member of the class and was most closely related to CL-ES2 and D1-W8, with similarities of 96.5 and 95.6 %, respectively. The major fatty acid was summed feature 8 (comprising Cω7 and/or Cω6). The polar lipids of DSW4-44 were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, an unidentified aminolipid, two unidentified lipids and three unidentified phospholipids. The isoprenoid quinone was Q-10. The DNA G+C content of DSW4-44 was 54.3 mol%. On the basis of evidence from a polyphasic study, strain DSW4-44 represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is DSW4-44 (=KCTC 62762=KCCM 43261=JCM 33637).
