Abstract

A Gram-reaction-negative, aerobic, rod-shaped (1.2–1.6 µm×0.6–0.8 µm), flagellated and motile marine bacterium, designated MEBiC06243, was isolated from a sediment collected at Daebu Island in the Yellow Sea (37° 20′ N 126° 41′ E), Korea. The 16S rRNA gene sequence analysis revealed that strain MEBiC06243 showed high similarity with NAG-2N-126 (96.3 %). Growth was observed at 10–39 °C (optimum 29 °C), at pH 6.0–9.0 (optimum pH 7) and with 0–7 % (optimum 2.5 %) NaCl. The predominant cellular fatty acids were C 3-OH (6.1 %), C (5.8 %), C (30.5 %), Cω7 (21.6 %) and summed feature 3 (comprising C 2-OH and/or Cω7; 30.7 %). The DNA G+C content was 41.4 mol%. The major respiratory quinone was Q-8. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, two unidentified lipids, one unidentified aminophospholipid and three unidentified aminolipids were detected as major polar lipids. On the basis of this polyphasic taxonomic data, strain MEBiC06243 should be classified as a novel species of the genus proposed as sp. nov. The type strain is MEBiC06243 ( = KCCM 42975 = JCM 18291). An emended description of the genus is also given.
