and has been restricted by recent phylogenetic studies to only include species closely related to '' Bacillus subtilis'' and '' Bacillus cereus.'' The name ''Salibacterium'' is derived from the prefix "-sali" (from the Latin noun ''sal/salis'', which translates to "salt"''),'' and the suffix "-bacterium" (from the Latin noun ''bacterium'', referring to a rod). Together, ''Salibacterium'' translates to a rod from salt.

Biochemical Characteristics and Molecular Signatures

Members of this genus are aerobic or facultatively anaerobic. Most members are non-motile, except ''S. aidingense'' which exhibits motility by means of peritrichous flagella. Some members form endospores. All of the members require salt for growth with optimal growth occurring in the presence of 10–12% (w/v) NaCl. Temperature range for growth is 15–45°C, with optimum growth temperature in the range 30-37°C. Nine conserved signature indels (CSIs) were identified for this genus in the following proteins: GTP-binding protein, CoA-binding protein, nucleoside triphosphatase YtkD, protease modulator HflC,

dihydrolipoyl dehydrogenase Dihydrolipoamide dehydrogenase (DLD), also known as dihydrolipoyl dehydrogenase, mitochondrial, is an enzyme that in humans is encoded by the ''DLD'' gene. DLD is a flavoprotein enzyme that oxidizes dihydrolipoamide to lipoamide. Dihydrolipoamid ...

These CSIs were identified through analyses of genome sequences from ''Salibacterium'' species and provide a reliable molecular means of differentiating this genus from other ''Bacillaceae'' genera and bacteria.

Taxonomy

''Salibacterium'', as of May 2021, contains a total of 7 species with validly published names. This branching pattern is also observed in the Genome Taxonomy Database (GTDB).
