Abstract

A Gram-negative, aerobic, motile and rod-shaped bacterium, designated strain T7-07, was isolated from compost in Daejeon, Korea. Phylogenetic analysis based on 16S rRNA gene sequencing showed that strain T7-07 had 99.0 % gene sequence similarity with KACC 14618 and 94.7–95.9 % with other recognized species of the genus . Cells formed creamy white to yellowish colonies on R2A agar and contained Q-8 as the predominant ubiquinone, C iso, C iso, C iso ω9 and C iso 3-OH as the major fatty acids, and diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmethylethanolamine and an unknown aminolipid as the major polar lipids. The DNA G+C content of strain T7-07 was 68.3 mol%. DNA–DNA reassociation experiments between T7-07 and KACC 14618 resulted in a mean relatedness value of 22.2 %. Combined genotypic and phenotypic data supported the conclusion that the strain T7-07 represents a novel species, for which the name sp. nov. is proposed. The type strain is T7-07 ( = KCTC 12667 = DSM 18060).
