Peribacillus
''Peribacillus'' is a genus of rod-shaped bacteria that exhibits Gram-positive bacteria, Gram-positive or Gram-variable staining that belongs in the family ''Bacillaceae'' within the order ''Bacillales''. The type species for this genus is ''Peribacillus simplex.'' Members of ''Peribacillus'' were originally part of the genus ''Bacillus'', a large, phylogenetically complicated genus with unclear evolutionary relationships. The polyphyletic nature of the genus could be partially attributed to the vague criteria used to classify new species into this genus. To clarify the taxonomic relationships of ''Bacillus'', multiple phylogenetic and comparative genomic analyses have been conducted, resulting in the transfer of many ''Bacillus'' species into novel genera such as ''Virgibacillus, Solibacillus, Brevibacillus'' and ''Ectobacillus''. In addition, the genus was restricted to only include species closely related to ''Bacillus subtilis'' and ''Bacillus cereus''. The name ''Peribacill ...

Bacillaceae
The Bacillaceae are a family of gram-positive, heterotrophic, rod-shaped bacteria that may produce endospores. Motile members of this family are characterized by peritrichous flagella. Some Bacillaceae are aerobic, while others are facultative or strict anaerobes. Most are not pathogenic, but ''Bacillus'' 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.

Nomenclature Taxa within this family are sometimes colloquially identified as bacilli. However, this term is ambiguous because it does not distinguish between class Bacilli, order Bacillales, family Bacilla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
