sp. nov., isolated from forest soil Free

Abstract

An aerobic, Gram-stain-negative, oxidase- and catalase-positive, non-motile, non-spore-forming, rod-shaped and yellow-coloured bacterium designated strain G-6-1-13 was isolated from Gwanggyo mountain forest soil. Strain G-6-1-13 could grow at 15–40 °C (optimum, 20–32 °C), pH 4.5–10.5 (optimum, pH 6.0–9.0), at 2 % (w/v) NaCl concentration, and produced flexirubin-type pigments. Phylogenetic analysis based on its 16S rRNA gene sequence showed that strain G-6-1-13 formed a lineage within the genus that was distinct from other species of the genus. Closest member was 10–7 W-9003 (98.6 % sequence similarity) followed by DSM 22224 (98.4 %), JN246 (97.6 %) and KP01 (97.4%). The major cellular fatty acids were iso-C, C 5, and summed feature 3 (iso-C 2-OH and/or C 6). MK-7 was the sole respiratory quinone. The major polar lipids were phosphatidylethanolamine and an unidentified phospholipid. The DNA G+C content of strain G-6-1-13 was 48.7 mol%. Average nucleotide identity and DNA–DNA hybridization were below the species threshold. On the basis of phenotypic, genotypic, phylogenetic and chemotaxonomic characterization, G-6-1-13 represents a novel species in the genus , for which the name sp. nov. is proposed. The type strain is G-6-1-13 (=KACC 21624=NBRC 114361).
