Abstract

A Gram-negative, aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated TR6-06, was isolated from a compost sample in South Korea and characterized taxonomically by using a polyphasic approach. The organism grew optimally at 30 °C and pH 6.5–7.0. The isolate was positive for catalase and oxidase tests, but negative for gelatinase and urease and for indole and HS production. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain TR6-06 was most closely affiliated with members of the genus of the family . Strain TR6-06 exhibited 16S rRNA gene sequence similarity values of 89.9–93.5 % to the type strains of species of the genus . The GC content of the genomic DNA of strain TR6-06 was 41.9 mol%. The predominant respiratory quinone was MK-7. The major fatty acids were iso-C, iso-C 3-OH, C 7 and anteiso-C. These chemotaxonomic data support the affiliation of strain TR6-06 to the genus . However, on the basis of its phenotypic properties and phylogenetic distinctiveness, strain TR6-06 (=KCTC 12638=LMG 23490) should be classified as the type strain of a novel species, for which the name sp. nov. is proposed.
