To elucidate the taxonomic position of "Rhodospirillum centenum" IAM 14193T (=ATCC 43720T) (T=type strain), a cyst-forming anoxygenic phototrophic bacterium, the small rRNA sequences (about 1, 300 bases) were determined for the organism, two cyst-forming isolates (MT-SP-2 and MT-SP-3), Rhodopseudomonas palustris ATCC 17001T and Erythrobacter longus JCM 6170T by using the reverse transcription-dideoxy sequencing method. "Rhodospirillum centenum" IAM 14193T and the two isolates had high phylogenetic affinity (98.8% homology). The sequences of the two isolates were identical. Comparative analysis of the presently determined sequences and the reference sequences (1, 107 bases) revealed that the three cyst-forming organisms belonged to the α group of the class Proteobacteria, and were distantly related to Rhodospirillum rubrum (the type species, α-1 subgroup) (89.9% homology) and the representative members of other subgroups (α-2, -3 and -4) (87.6-89.8% homology). They constituted a new phylogenetic branch in the α group. "Rhodospirillum centenum" IAM 14193T possessed Q-9 as the major quinone but no rhodoquinones or menaquinones, that was a quinone system distinct from that of other anoxygenic phototrophs. The phylogenetic evidence and the phenotypic characteristics indicated that "Rhodospirillum centenum" IAM 14193T did not belong to the genus Rhodospirillum. We proposed Rhodocista centenaria gen. nov., sp. nov. for the organism.
