De.sul.fo.sar.ci.na.ce'ae. N.L. fem. n.Desulfosarcina, type genus of the family; suff. ‐aceae, ending to denote a family; N.L. fem. pl. n.Desulfosarcinaceae, the family ofDesulfosarcina.Desulfobacterota / Desulfobacteria / Desulfobacterales / DesulfosarcinaceaeCells are rod shaped and occur singly, in pairs, or as aggregate‐like packages. Gram‐stain‐negative. Endospores are not observed. Motile or nonmotile. Strict anaerobes with respiratory and fermentative (some species) types of metabolism. Chemoorganoheterotrophs and chemolithoautotrophs. Simple organic compounds, such as short‐chain fatty acids and, in some species, dicarboxylic acids, alkanes, benzoate, and metylated monocyclic aromatic hydrocarbons, serve as electron donors and carbon sources and are oxidized to CO2via the anaerobic C1‐pathway (carbon monoxide dehydrogenase [CODH] or Wood–Ljungdahl pathway). Chemolithoautotrophic growth on H2and CO2. Formate is used without acetate. Sulfate serves as a terminal electron acceptor and reduced to H2S; thiosulfate and sulfite are used as well by some species. Mesophilic. Neutrophilic. The major menaquinone is MK‐7 (only determined for the genusDesulfosarcina). The family currently accommodates two genera,DesulfosarcinaandDesulfatitalea. Members of this family are found in anoxic brackish water and marine habitats including water‐flooded oil fields.DNA G + C content (mol%): 51.0–57.0 (genome, LC).Type genus:DesulfosarcinaWiddel 1981VP(Effective publication: Widdel 1980) emend.
