Abstract

The taxonomic position of a Gram-positive, non-spore-forming strain, designated CAU 59, from activated sludge was investigated. Colony morphology, biochemical tests and chemotaxonomic investigations revealed that strain CAU 59 possessed the characteristics of the genus . Comparative 16S rRNA gene sequence analysis showed sequence divergence values between strain CAU 59 and other described species of more than 3.6 %, and the strain formed a hitherto-unknown subline within the genus . DNA–DNA hybridization studies showed that strain CAU 59 displayed 20.9 % relatedness to its closest phylogenetic neighbour, DSM 20419. The DNA G+C content was 66.2 mol%. The phenotypic, chemotaxonomic and genotypic data indicated that strain CAU 59 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is CAU 59 (=KCTC 22691 =CCUG 58142).
