Abstract

A Gram-stain-negative, strictly aerobic, non-flagellated and rod-shaped bacterial strain, designated GJR-7, was isolated from coastal sand of the South Sea of South Korea. Strain GJR-7 grew optimally at 30 °C, at pH 7.0–7.5 and without NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain GJR-7 clustered with the type strains of , and , with which it exhibited 16S rRNA gene sequence similarity values of 96.0–96.3 %. Sequence similarities to the type strains of other recognized species were less than 95.5 %. Strain GJR-7 contained Q-10 as the predominant ubiquinone and Cω7, 11-methyl Cω7 and summed feature 3 (Cω7 and/or Cω6) or C 2-OH. The major polar lipids were sphingoglycolipid, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and one unidentified glycolipid. The DNA G+C content of strain GJR-7 was 55.5 mol%. Differential phenotypic properties, together with phylogenetic distinctiveness, revealed that strain GJR-7 is separated from the type strains of , and . On the basis of the data presented, strain GJR-7 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is GJR-7 ( = KCTC 42051 = CECT 8531). It is also proposed that and should be reclassified as members of the genus .
