Abstract

A study employing a polyphasic taxonomic approach was undertaken to clarify the position of 12 isolates recovered from sewage samples. These isolates were recognized as a potential novel species because a new and specific pattern was produced with the 16S rRNA-RFLP identification method. The sequences of the 16S rRNA gene not only supported the classification of these novel strains as members of the genus , but also showed that they formed a separate phylogenetic line. Strain SW28-11, chosen as the representative of these strains, showed 16S rRNA gene sequence similarity of 95.6 % with the closest related species . The phylogenetic position of the novel strains was further confirmed by analysis of the housekeeping genes , and, for the first time, . The latter proved to be an excellent additional gene for establishing the phylogeny of this genus. These data, together with phenotypic characterization, revealed that this group of isolates represent a novel species of the genus . The name sp. nov., is proposed, with the type strain SW28-11 ( = CECT 7697 = LMG 25694).
