Abstract

Similarities in phylogeny and metabolic properties between the type species of two monospecific genera of thermophilic anaerobic bacteria, and , and analysis of their recently available 16S rRNA gene sequences warranted clarification of their taxonomic positions. We have determined that the value of DNA–DNA hybridization between the type strains is 53 %. Additional physiological studies revealed that Z-2901 is capable of Fe(III) reduction with H as an electron donor and ferrihydrite as an electron acceptor. JW/AS-Y7 is able to grow and utilize CO with ferrihydrite as an electron acceptor without hydrogen or acetate production. We therefore reclassify as comb. nov. (type strain JW/AS-Y7=DSM 11255=VKM B-2392). The description of the genus is emended to include such important physiological properties as growth on organic compounds and capacity for Fe(III) reduction.
