Abstract

and were described independently in 2011. Their type strains showed high levels of 16S rRNA gene sequence similarity (99.3 %). Phylogenetic analysis revealed that MCC 2278 and JCM 16166 formed a monophyletic group and showed distant relationships to other members of closely related genera such as , , and . The presence of large proportions of iso-C and iso-C with small amounts of iso-C distinguished MCC 2278 and JCM 16166 from other members of the genera and . Unlike other members of the genera and , MCC 2278 and JCM 16166 showed growth at low concentrations of NaCl. Thus, based on distinctive phylogenetic, chemotaxonomic and physiological features of these two organisms in comparison with other members of the genera and it is clear that they do not fit within the existing classification and deserve separate status. DNA–DNA hybridization between the two type strains was 63 %, indicating that they represent separate species. In this study, we propose the creation of a novel genus, gen. nov., to accommodate the two species with gen. nov., comb. nov. (type strain JCM 16166 = KCTC 19557) as the type species. comb. nov. (type strain MCC 2278 = DSM 23694) is also proposed.
