Abstract'ae. N.L. masc. n. Thermohalobacter , type genus of the family; suff. ‐aceae , ending to denote a family; N.L. fem. pl. n. Thermohalobacteraceae , the Thermohalobacter family. Firmicutes / Clostridia / Tissierellales / Thermohalobacteraceae fam. nov. Free‐living bacteria that mainly occur in anoxic saline environments. Cells are not pigmented and have a Gram‐positive type of cell wall. Gram‐stain reaction can be negative or positive. Typically slender rod‐shaped cells that are motile by flagella. Several strains form heat‐resistant spores. Mainly euryhaline, moderately thermophilic and halophilic. Members of the family are strictly anaerobic bacteria that utilize carbohydrates or peptides by fermentation. Cellular fatty acid patterns are dominated by iso ‐C 15:0 and iso ‐C 15:0 DMA. The family currently accommodates members of the genera Thermohalobacter , Caldisalinibacter , Caloranaerobacter , Brassicibacter , Sporosalibacterium , and Clostridiisalibacter , which were previously affiliated with the family Clostridiaceae . The affiliation of novel species to this family depends on the phylogenetic position, which should be determined on the basis of comparative sequence analyses of 16S rRNA genes or genomes. DNA G + C content (mol%): 28–33. Type genus: Thermohalobacter Cayol et al. 2000.
