Abstract
A Gram-stain-negative, strictly aerobic, non-spore-forming, rod-shaped, motile with polar flagella and pale-orange bacterium, designated strain 122213-3T, was isolated from air, collected at the foot of the Xiangshan Mountain, located in Beijing, PR China. Optimal growth occurred at 28 °C, at pH 7 and in the presence of 0–1 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that 122213-3T clustered with species of the genus
Noviherbaspirillum
and formed a distinct sublineage, showing highest similarities to
Noviherbaspirillum malthae
CC-AFH3T (96.88 %),
Noviherbaspirillum massiliense
JC206T (95.78 %) and
Noviherbaspirillum aurantiacum
SUEMI08T (95.78 %). The predominant cellular fatty acids were summed feature 3 (C16 : 1
ω6c and/or C16 : 1
ω7c), summed feature 8 (C18 : 1
ω7c and/or C18 : 1
ω6c) and C16 : 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 122213-3T 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 122213-3T (=CFCC 14286T=LMG 30131T).
