摘要：A Gram-stain-negative, strictly aerobic, non-spore-forming, rod-shaped, motile with polar flagella and pale-orange bacterium, designated strain 122213-3(T), was isolated from air, collected at the foot of the Xiangshan Mountain, located in Beijing, PR China. Optimal growth occurred at 28 degrees C, at pH 7 and in the presence of 0-1% (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that 122213-3(T) clustered with species of the genus Noviherbaspirillum and formed a distinct sublineage, showing highest similarities to Noviherbaspirillum malthae CC-AFH3(T) (96.88 %), Noviherbaspirillum massiliense JC206(T) (95.78 %) and Noviherbaspirillum aurantiacum SUEMI08(T) (95.78 %). The predominant cellular fatty acids were summed feature 3 (C-16:1 omega 6c and/or C-16:1 omega 7c), summed feature 8 (C-18:1 omega 7c and/or C-18:1 omega 6c) and C-16:0. The predominant quinone was ubiquinone 8 (Q-8). The polar lipids comprised phosphatidylethanolamine, phosphatidylglycerol, unidentified phospholipid and two unidentified polar lipids. The polyamine pattern showed the presence of putrescine as the major polyamine, with minor amounts of 2-hydroxyputrescine. The DNA G+C content was 60.1 mol%. The phylogenetic analysis and physiological and biochemical data showed that strain 122213-3(T) should be classified as representing a novel species in the genus Noviherbaspirillum, for which the name Noviherbaspirillum aerium sp. nov. is proposed. The type strain of N. aerium is 122213-3(T) (=CFCC 14286(T)=LMG 30131(T)).
