    Abstract:
    A novel dark pink pigmented bacterium, designated strain CPCC 100847T (deposited with strain code 0113-15), was isolated from the urban air of Beijing, China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CPCC 100847T was related to members of the genus Roseomonas and had the highest 16S rRNA gene sequence similarity to Roseomonas aestuarii JC17T (97.5 %). A low level of DNA-DNA relatedness (18.7 %) with its closest type strain R. aestuarii JC17T (KCTC 22692T) proved that strain CPCC 100847T belonged to a unique genomic species. CPCC 100847T had many common characteristics of the genus Roseomonas, but also had a range of cultural, physiological and biochemical characteristics that separated it from related Roseomonas species. Cells were Gram-negative, cocci- to oval-shaped, non-motile, non-endospore-forming and strictly aerobic. The respiratory ubiquinone was Q-10. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an unidentified aminolipid and an unidentified phospholipid. The major fatty acids (>5 %) were C18 : 1ω7c, anteiso-C15 : 0, C16 : 0, iso-C15 : 0 and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The combined genotypic and phenotypic data indicated that the isolate represents a novel species of the genus Roseomonas. The name proposed for this species is Roseomonasglobiformis sp. nov., with CPCC 100847T (=KCTC 52094T) as the type strain. The DNA G+C composition is 65.2 mol%.
