Abstract

A Gram-positive, aerobic, motile, coccoid or short rod-shaped bacterium, 5420S-23, was isolated from an air sample collected in the Republic of Korea. According to phylogenetic analysis based on 16S rRNA gene sequences, strain 5420S-23 revealed 97.5, 97.3, 97.3 and 97.2 % similarity, respectively, to DSM 20112, DSM 20118, DSM 20113 and X.bu-b. The peptidoglycan type of strain 5420S-23 was A4, containing -ornithine–-glutamic acid. The cell-wall sugars were galactose, glucose and xylose. The major fatty acids were anteiso-C (49.7 %) and C (20.0 %). The major menaquinone was MK-9(H) and major polar lipids were diphosphatidylglycerol and phosphatidylglycerol. The DNA G+C content was 74 mol%. The results of DNA–DNA hybridization with strains of closely related species, in combination with chemotaxonomic and physiological data, demonstrated that isolate 5420S-23 represents a novel species, for which the name sp. nov. is proposed, with strain 5420S-23 (=KACC 20692 =DSM 18649) as the type strain.
