Abstract

A Gram-negative, aerobic, short rod-shaped bacterium, designated strain YC6898, was isolated from the surface-sterilized root of a halophyte () inhabiting tidal flat of Namhae Island, Korea. Strain YC6898 grew optimally at 30–37 °C and pH 6.5–7.5. The strain inhibited mycelial growth of and . Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain YC6898 belongs to the genus in the family . Its closest relatives were AM1V30 (96.7 % 16S rRNA gene sequence similarity), WH2K (95.7 %), DFL-43 (95.5 %) and LMG 128 (94.8 %). Strain YC6898 contained Q-10 as the major ubiquinone. The major fatty acids of strain YC6898 were Cω7 (61.1 %), C (11.9 %), 11-methyl Cω7 (9.6 %) and C cyclo ω8 (8.0 %). The polar lipids were phosphatidylcholine, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylglycerol, unknown lipids and an unknown glycolipid. The total genomic DNA G+C content was 53.7 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic analysis, strain YC6898 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is YC6898 ( = KACC 14911 = NBRC 107700).
