sp. nov., an airborne bacteria isolated from an urban area of Beijing, China.

A Gram-negative, ellipsoidal to short-rod-shaped, motile bacterium was isolated from Beijing's urban air. The isolate exhibited the closest kinship with 122213-3, exhibiting 98.4 % 16S rRNA gene sequence similarity.

Isolation, Characterization, and Antimicrobial Activity of Bacterial and Fungal Representatives Associated With Particulate Matter During Haze and Non-haze Days.

Particulate matter (PM) has been a threat to the environment and public health in the metropolises of developing industrial countries such as Beijing. The microorganisms associated with PM have an impact on human health if they are exposed to the respiratory tract persistently. There are few reports on the microbial resources collected from PM and their antimicrobial activities.

Ornithinimicrobium cerasi sp. nov., isolated from the fruit of and emended description of the genus .

Strain CPCC 203383, isolated from the surface-sterilized fruit of (Lindl.) G. Don, was taxonomically characterized based on a polyphasic investigation.

Roseomonas globiformis sp. nov., an airborne bacteria isolated from an urban area of Beijing.

A novel dark pink pigmented bacterium, designated strain CPCC 100847 (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 100847 was related to members of the genus Roseomonas and had the highest 16S rRNA gene sequence similarity to Roseomonas aestuarii JC17 (97.5 %).

Glycomyces paridis sp. nov., isolated from the medicinal plant Paris polyphylla.

Three actinomycete strains originating from the surface-sterilized roots of Paris polyphylla were characterized by using a polyphasic approach. Phylogenetic analyses based on the 16S rRNA gene sequence showed that they formed a deep, monophyletic branch in the genus Glycomyces, and were most closely related to the type strains of the species Glycomyces harbinensis and Glycomycesscopariae. Morphological and chemotaxonomic data supported the affiliation of strains CPCC 204357, CPCC 204354 and CPCC 204355 to the genus Glycomyces.

Ornithinimicrobium flavum sp. nov., isolated from the leaf of Paris polyphylla.

A Gram-positive bacterium originating from the surface-sterilized leaf of Paris polyphylla var. yunnanensis (Franch.) was characterized by using a polyphasic approach.
