Abstract

A Gram-stain-negative, variably shaped, non-flagellated, yellow-pigmented, aerobic bacterium, designated strain SGM2-10, was isolated from a paddy soil sample from the Suwon region, South Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate was related most closely to RHYL-37. Strain SGM2-10 showed highest 16S rRNA gene sequence similarity to RHYL-37 (95.1 %), HY-50R (95.0 %) and JCN-23 (94.4 %). No other species in the family shared more than 94.1 % 16S rRNA gene sequence similarity with strain SGM2-10. The major fatty acids of strain SGM2-10 were iso-C, iso-C G and iso-C 3-OH. The only menaquinone was MK-7. The polar lipids comprised phosphatidylethanolamine, seven unknown lipids and ten unknown aminolipids. The G+C content of the DNA of strain SGM2-10 was 46.7 mol%. On the basis of the results of the polyphasic characterization presented in this study, it is concluded that strain SGM2-10 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is SGM2-10 ( = KACC 17341 = JCM 19942). The description of the genus has also been emended.
