Roseomonas aerilata sp. nov., isolated from an air sample.
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(T), grew in the temperature range of 5-35 degrees C (optimum 30 degrees 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(18 : 1)omega7c, summed feature 3 (C(16 : 1)omega7c/iso-C(15 : 0) 2-OH) and C(16 : 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-30(T) 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 TR53(T) and Roseomonas gilardii ATCC 49956(T). On the basis of its phenotypic and genotypic characteristics, strain 5420S-30(T) represents a novel species of the genus Roseomonas, for which the name Roseomonas aerilata sp. nov. is proposed, with 5420S-30(T) (=KACC 12521(T) =DSM 19363(T)) as the type strain.
