A novel strain, designated 5715S-12^T, 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-12^T showed the highest sequence similarities to Aurantimonas altamirensis S21B^T (95.9 %) and Aurantimonas coralicida WP1^T (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 C_{18 : 1}7c. 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-12^T be assigned to a novel species of the genus Aurantimonas, for which the name Aurantimonas ureilytica sp. nov. (type strain 5715S-12^T =KACC 11607^T =DSM 18598^T) is proposed.

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain 5715S-12^T is DQ883810.

A transmission electron micrograph of a cell of strain 5715S-12^T, polar lipid profiles of strain 5715S-12^T and related strains and a 16S rRNA gene sequence-based maximum-parsimony tree are available as supplementary material with the online version of this paper.
