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-30, 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 C 7, summed feature 3 (C 7/iso-C 2-OH) and C (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-30 and members of the genus were in the range 91.6–95.1 %, with the highest sequence similarities (95.1 and 94.5 %, respectively) to TR53 and ATCC 49956. On the basis of its phenotypic and genotypic characteristics, strain 5420S-30 represents a novel species of the genus , for which the name sp. nov. is proposed, with 5420S-30 (=KACC 12521 =DSM 19363) as the type strain.
