Abstract

Strain GR3 was isolated from drinking water during a screening programme to monitor the bacterial population present in the distribution system of Seville (Spain), and it was studied phenotypically, genotypically and phylogenetically. This pink-pigmented bacterium was identified as a sp. Members of this genus are distributed in a wide variety of natural habitats, including soil, dust, air, freshwater and aquatic sediments. Phylogenetic analysis of the 16S rRNA gene sequence showed that strain GR3 was closely related to (97·4 % sequence similarity), whereas sequence similarity values with respect to the rest of the species belonging to this genus were lower than 96 %. Furthermore, the DNA–DNA hybridization data and its phenotypic characteristics clearly indicate that the isolate represents a novel species, for which the name sp. nov. is proposed. GR3 (=DSM 16961=CCM 7281=CECT 7045) is the type strain; the DNA G+C content of this strain is 69·2 mol%.
