A Gram-negative, aerobic, non-spore-forming, non-motile, yellow-pigmented and rod-shaped bacterial strain, designated B093034 T , was isolated from air at the foot of Xiangshan mountain, located in Beijing, China. Cells of strain B093034 T were oxidase-negative and catalase-positive. Growth was observed at 4-41 °C, at pH 4.5-10.0 and at 0-7 % (w/v) NaCl. The isolate contained Q-10 as the predominant isoprenoid quinone, summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), C16 : 0 and C14 : 02-OH as the major fatty acids, sym-homospermidine as the major polyamine, and sphingoglycolipid, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, diphosphatidylglycerol, aminolipid, two unidentified phospholipids and three unidentified polar lipids as the polar lipids. The DNA G+C content was 67.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain B093034 T grouped with members of the genus Sphingomonas and was closely related to Sphingomonas sanguinis IFO 13937 T (96.49 % similarity), Sphingomonas pseudosanguinis G1-2 T (96.37 %), Sphingomonas ginsenosidimutansGsoil 1429 T (95.99 %) and Sphingomonas endophytica YIM 65583 T (95.78 %). On the basis of the polyphasic evidence presented here, strain B093034 T represents a novel species of the genus Sphingomonas, for which the name Sphingomonasaeria sp. nov. is proposed. The type strain is B093034 T (=CFCC 13949 T =LMG 30133 T ). |
