Abstract

An aerobic, yellow-pigmented, Gram-staining-negative bacterium, designated strain H7, was isolated from sediment of Gazwa stream in Jinju city, South Korea. Cells of strain H7 were non-motile, straight rods that produced flexirubin pigments and showed catalase- and oxidase activities. Strain H7 contained iso-C anteiso-C and summed feature 3 (comprising C 7 and/or iso-C 2-OH) as the main fatty acids and menaquinone-6 (MK-6) as the major isoprenoid quinone. The DNA G+C content of strain H7 was 37.2 mol%. Comparative 16S rRNA gene sequence analysis showed that strain H7 formed a distinct phyletic line within the genus . Based on 16S rRNA gene sequence similarities, the novel strain was most closely related to ST-82 and BD-b365 with 97.2 % and 97.0 % gene sequence similarities, respectively. The DNA–DNA relatedness of the novel strain with these species was only 18 % and 14 %, respectively. On the basis of phenotypic data and molecular properties, strain H7 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is H7 (=KACC 12818=DSM 19978).
