| Genera[1] | |
Bacillaceae is a family of bacteria in the class Bacilli. Its type genus is Bacillus.[1] Members of the family are morphologically and physiologically diverse. Many are Gram-positive or Gram-variable, rod-shaped, heterotrophic bacteria that produce endospores, although non-spore-forming and coccoid members also occur.[2]
The family includes aerobic, facultatively anaerobic, and anaerobic organisms. Motility varies among its members, with many motile species possessing peritrichous flagella.[2]
Taxonomy
[edit]The family name is formed from the name of its type genus, Bacillus, and the family-rank suffix -aceae.[1] The circumscription of Bacillaceae differs among taxonomic treatments. LPSN records 120 child genera with validly published and correct names in the family.[1]
A genome-based revision of the order Caryophanales analyzed core-genome phylogeny, average amino-acid identity, lineage-specific genes, and phenotypic characteristics. In that treatment, Bacillaceae was restricted to Bacillus, Ectobacillus, Gottfriedia, and Metabacillus, while numerous other genera were assigned to separate families. The restricted Bacillaceae was nevertheless reported to be non-monophyletic, with its members forming two distinct clades in both phylogenomic and 16S rRNA gene trees.[3]

Terminology
[edit]The informal word "bacilli" may refer generally to rod-shaped bacteria. It should not be confused with the formal taxonomic names Bacilli at the class rank, Bacillales at the order rank, Bacillaceae at the family rank, or Bacillus at the genus rank.
