Roseomonas pecuniae sp. nov., isolated from the surface of a copper-alloy coin.
Strain N75(T) was isolated from the surface of a copper-alloy 50 Euro cent coin collected from general circulation. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain N75(T) formed a distinct branch within the genus Roseomonas and placed it in the Alphaproteobacteria. Strain N75(T) showed 16S rRNA gene sequence similarities of 92.4-97.1  % to type strains of species of the genus Roseomonas. Strain N75(T) was a Gram-negative, non-spore-forming, non-motile coccoid, with an optimum growth temperature of about 30 °C; the strain did not grow at 5 or 37 °C. Strain N75(T) did not grow in medium containing NaCl. The major respiratory quinone was ubiquinone 10 (Q-10). The major fatty acids were unsaturated C₁₆:₁ω7c/C₁₆:₁ω6c and C₁₈:₁ω7c (around 70 % of the total fatty acids); the third most abundant fatty acid was the hydroxylated C₁₈:₁ 2-OH. The major polar lipids were phosphatidylcholine, phosphatidylethanolamine and an unknown aminolipid. The DNA G+C content was 72.8 mol%. On the basis of the phylogenetic analysis and physiological and biochemical characteristics, we conclude that strain N75(T) represents a novel species of the genus Roseomonas, for which we propose the name Roseomonas pecuniae sp. nov. (type strain N75(T) =LMG 25481(T) =CIP 110074(T)).
