An endospore-forming, rod-shaped bacterium was isolated from the rhizosphere of willow roots in Korea. The bacterium, designated strain BR030, was a strictly aerobic, motile rod. The cell wall contained type A1 peptidoglycan with -diaminopimelic acid as the diagnostic diamino acid. The major cellular fatty acids were anteiso-C, iso-C, iso-C and iso-C. The major cellular phospholipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and unknown phospholipids (PL1, PL2). The genomic DNA G+C content was 36 mol%. Comparative 16S rRNA gene sequence analyses showed that strain BR030 formed a distinct phyletic line within the genus and was most closely related to DSM 1320, with 16S rRNA gene sequence similarity of 96·8 %. Sequence similarities to other type strains were lower than 96·2 %. On the basis of physiological and molecular properties, the isolate represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is BR030 (=KCTC 3914=DSM 16467).
