Bacillaceae is a family of Gram-positive, heterotrophic, rod-shaped bacteria that may produce endospores. [Bergey's Manual of Systematic Bacteriology (2 ed.), Volume 3. 2008. "The low G + C Gram-positive Bacteria". Editors: De Vos, P., Garrity, G., Jones, D., Krieg, N.R., Ludwig, W., Rainey, F.A., Schleifer, K.-H. and W.B. Whitman. ISBN 0-387-95041-9] Motile members of this family are characterized by peritrichous flagellae. Some Bacillaceae are aerobic, while others are facultative or strict anaerobes. Most are non-pathogenic, but "Bacillus" and "Clostridium" species are known to cause disease in humans.

Gram-variable cell wall

Some Bacillaceae, such as the genera "Filobacillus, Lentibacillus and Halobacillus", stain Gram-negative or Gram-variable, but are known to have a Gram-positive cell wall. [Lim, J.M., Jeon, C.O., Song, S.M., and C.J. Kim. 2005. [http://ijs.sgmjournals.org/cgi/content/full/55/1/165?ck=nck "Pontibacillus chungwhensis gen. nov., sp. nov., a moderately halophilic Gram-positive bacterium from a solar saltern in Korea"] . Int. J. Syst. Evol. Microbiol. 55:165-170.]

Nomenclature

Genera within this family are sometimes colloquially identified as bacilli. However, this term is a misnomer because it does not distinguish between class Bacilli, order Bacillales, family Bacillaceae and genus "Bacillus".
