Abstract

A Gram-stain-negative, strictly aerobic, pale-pink-pigmented bacterium, designated strain G27, was isolated from a volcanic forest of Jeju Island, South Korea. Cells were catalase- and oxidase-positive, non-motile rods producing exopolysaccharide and flexirubin-type and pale pink pigments. Growth of strain G27 was observed at 4–30 °C (optimum, 25 °C) and pH 5.0–8.0 (optimum, pH 7.0). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain G27 formed a phyletic lineage within the genus of the family . Strain G27 was related most closely to Gh-67 at 96.5 % 16S rRNA gene sequence similarity. Strain G27 contained menaquinone 7 (MK-7) as the sole isoprenoid quinone and summed feature 3 (comprising C ω7/C ω6), iso-C , C , C ω5 and C ω5 as the major cellular fatty acids. Phosphatidylethanolamine was identified as the major polar lipid. The G+C content of the genomic DNA was 46.5 mol%. On the basis of phenotypic, chemotaxonomic and molecular properties, strain G27 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is G27 ( = KACC 18231 = JCM 30363).
