Roseomonas aquatica sp nov., isolated from drinking water

Strain TR53(T), a Gram-negative, non-motile, non-spore-forming and strictly aerobic coccobacillus, isolated from the drinking water distribution system of Seville, Spain, was subjected to polyphasic taxonomic analysis using a combination of phenotypic, genotypic and phylogenetic features. Phylogenetic analysis of 16S rRNA gene sequences showed that strain TR53(T) had highest similarity to members of the genus Roseomonas, with sequence similarity values between 95 center dot 7% (to Roseomonas genomospecies 5 strain ATCC 49960) and 94 center dot 0% (to Roseomonas gilardii subsp. rosea ATCC 49956(T)). On the basis of its phenotypic characteristics, 16S rRNA gene sequence data and DNA G + C content (68 center dot 6 mol%), strain TR53(T) represents a novel species of the genus Roseomonas, for which the name Roseomonas aquatica sp. nov. is proposed. The type strain of Roseomonas aquatica is TR53T (=CECT 713(T) = JCM 13556(T)).
