Abstract

Comparison of both 16S rRNA coding sequences and DNA-DNA hybridization of ten strains of α-subclass of currently classified as strains of has shown that they fall into two groups which are distinct from each other at the species level. Comparison with published data on the cytochrome profiles and other 16S rRNA coding sequences in the literature has confirmed these observations and enabled several other strains also to be assigned to these two groups. Group A comprises strains ATCC 17741(the type strain of ), LMD 22.21, DSM 413, ATCC 19367, ATCC 13543, DSM 1404, DSM 1405, Pd 1222 (a genetic modification of DSM 413) and NCIMB 8944. Group B comprises ATCC 35512(the original type strain of ), LMD 82.5, LMD 92.63, DSM 65, LMG 4218, IAM 12479, JCM 6892, DSM 11072, DSM 11073 and DSM 11104. In light of these findings, it is proposed that: (1) strains of group A are retained as , with ATCC 17741as the type strain of the type species; and (2) all strains of group B are assigned to the new species combination comb. nov., with strain ATCC 35512as the type strain. Comparative 16S rRNA sequence analysis and DNA-DNA hybridization of strains of confirm that this species is distinct from both and , but that its nearest phylogenetic neighbour is .
