Thiohalomonadaceae fam. nov.

Abstract Thi.o.ha.lo.mo.nad.a.ce'ae N.L. fem. n. Thiohalomonas , the type genus of the family, ‐ aceae ending to denote a family; N.L. fem. pl. n. Thiohalomonadaceae the Thiohalomonas family. Proteobacteria / Gammaproteobacteria / Thiohalomonadales / Thiohalomonadaceae fam. nov. The family Thiohalomonadaceae accommodates facultatively anaerobic, chemolithoautotrophic sulfur‐oxidizing bacteria. They utilize reduced sulfur compounds as the energy source and either oxygen or NO x as the electron acceptors. CO 2 is assimilated via the Calvin–Benson–Bassham cycle. The family is a member of the order Thiohalomonadales in the Gammaproteobacteria and consists of the genera Thiohalomonas and Sulfurivermis . The family‐level status was established by phylogenomic analysis based on 120 single‐copy conserved protein markers. DNA G + C content (mol%) : 58–65 ( T m of 3 species). Type genus : Thiohalomonas Sorokin et al. 2007 VP .
