Aurantimonas ureilytica sp. nov., isolated from an air sample

Abstract

A novel strain, designated 5715S-12T, was isolated from an air sample collected from Suwon region, Republic of Korea, using R2A medium. The cells were strictly aerobic, Gram-negative, motile, short rods. Comparison of the 16S rRNA gene sequence of strain 5715S-12T showed the highest sequence similarities to Aurantimonas altamirensis S21BT (95.9 %) and Aurantimonas coralicida WP1T (95.4 %). Phylogenetic trees indicated that the strain formed a cluster with members of the family Aurantimonadaceae (A. altamirensis, A. coralicida and Fulvimarina pelagi). The major fatty acid was C18 : 1 ω7c. The predominant isoprenoid quinone was ubiquinone 10 (Q-10). Diphosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, phosphatidyldimethylethanolamine, phosphatidylglycerol, phosphatidylcholine and four unknown lipids were found as the polar lipid components. The DNA G+C content was 67.0 mol%. On the basis of the phenotypic and phylogenetic features studied, we propose that strain 5715S-12T be assigned to a novel species of the genus Aurantimonas, for which the name Aurantimonas ureilytica sp. nov. (type strain 5715S-12T =KACC 11607T =DSM 18598T) is proposed.
