A soil isolate, strain CC-AB07T, was characterized using a polyphasic approach. This organism had chemotaxonomic and morphological properties consistent with its classification in the genus Gordonia. 16S rRNA gene sequence analysis showed that the novel strain formed a monophyletic branch at the periphery of the evolutionary radiation occupied by the genus Gordonia, its closest neighbours being the type strains of Gordonia alkanivorans, Gordonia amicalis, Gordonia bronchialis, Gordonia desulfuricans, Gordonia polyisoprenivorans and Gordonia rhizosphera. The novel isolate was distinguished from all of these type strains using a range of phenotypic properties and by gyrB gene sequence analysis. It was evident from the genotypic and phenotypic data that strain CC-AB07T should be classified as representing a novel species in the genus Gordonia, for which the name Gordonia soli sp. nov. is proposed. The type strain is CC-AB07T (=BCRC 16810T=DSM 44995T).
