A polyphasic study was carried out to clarify the taxonomic position of a pink-coloured, Gram-negative bacterium isolated from air in the Suwon region of Korea. The novel strain, 5420S-30T, grew in the temperature range of 5–35 °C (optimum 30 °C) and pH range of 5–9 (optimum pH 6–7). Growth did not occur in the presence of as little as 1 % (w/v) NaCl. It contained Q-10 as the predominant ubiquinone. The major fatty acids were C18 : 1{omega}7c, summed feature 3 (C16 : 1{omega}7c/iso-C15 : 0 2-OH) and C16 : 0 (together representing 77.7 % of the total). The DNA G+C content was 72.1 mol%. The 16S rRNA gene sequence similarities between strain 5420S-30T and members of the genus Roseomonas were in the range 91.6–95.1 %, with the highest sequence similarities (95.1 and 94.5 %, respectively) to Roseomonas aquatica TR53T and Roseomonas gilardii ATCC 49956T. On the basis of its phenotypic and genotypic characteristics, strain 5420S-30T represents a novel species of the genus Roseomonas, for which the name Roseomonas aerilata sp. nov. is proposed, with 5420S-30T (=KACC 12521T =DSM 19363T) as the type strain.

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain 5420S-30T is EF661571.
