Thiohalorhabdaceae fam. nov.

Abstract

Thi.o.ha.lo.rhab.da.ce’ae N.L. fem. n. Thiohalorhabdus, the type genus of the family; L. fem. pl. n. suff.-aceae, ending to denote a family; N.L. fem. pl. n. Thiohalorhabdaceae, the Thiohalorhabdus family.
The family Thiohalorhabdaceae incorporates facultatively anaerobic, chemolithoautotrophic, sulfur-oxidizing bacteria from hypersaline habitats. They are extreme halophiles utilizing reduced sulfur compounds as energy sources with either O₂ or nitrate as the electron acceptor and assimilating CO₂ via the Calvin–Benson–Bassham cycle. The family is a member of the order Thiohalorhabdales in the Gammaproteobacteria, and it consists of a single genus Thiohalorhabdus. The family-level status was established by phylogenomic analysis based on the Genome Taxonomy DataBase classification. DNA G +C content (%): 68.9 (genome of the type strain). Type genus: Thiohalorhabdus Sorokin et al. 2008^VP.
