Abstract

The taxonomic status of Takayanagi . 1996 was re-evaluated by fresh determinations of the 16S rDNA sequence and G+C content of the genomic DNA of the type strain, HO1-1. The 16S rDNA sequence of strain HO1-1 showed 98 % similarity to those of two species and only ⩽92 % similarity to those of other species. The DNA G+C content (46·2 mol%) is in accordance with those of species. In addition, strain HO1-1 shares some phenotypic properties with species; however, it can be differentiated from them by its capacity to utilize FeS and tetrathionate and the absence of flagella. Therefore, it is proposed that should be transferred to the genus as comb. nov.
