Bacillus, from Latin "bacillus", meaning "little staff, wand", is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Bacillota, with 266 named species. The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural Bacilli is the name of the class of bacteria to which this genus belongs. Bacillus species can be either obligate aerobes which are dependent on oxygen, or facultative anaerobes which can survive in the absence of oxygen. Cultured Bacillus species test positive for the enzyme catalase if oxygen has been used or is present.

OverviewAI-generated

Bacillus is a genus of gram-positive bacteria within the family Bacillaceae. It belongs to the order Bacillales, class Bacili, and phylum Firmicutes. The taxon was described by Cohn in 1872 and is currently accepted. *Bacillus subtilis* serves as the taxonomic type for this genus, which also functions as the nomenclatural type for Bacillati, Bacillota, Bacilli, and Bacillales.

The organism inhabits both marine and freshwater environments. Records from the iDigBio database indicate 841 entries associated with this genus, including 35 media items, with institutions such as CIIDIR-IPN in Mexico listed among the sources. Additionally, the genus is referenced by 456 other encyclopedia articles.

Les Bacillus forment un genre de bactéries à gram positif, appartenant à la famille des bacillacées (Bacillaceae), l’ordre des bacillales (Bacillales), la classe des bacilles (Bacillis), le phyllum des firmicutes (Firmicutes). De forme bacilles, les dimensions de ces bactéries sont variables ; elles peuvent aller de (0.5 × 1.2 µm) à (2.5 × 10 µm). Elles sont aérobies ou aéro-anaérobies facultatives, et tirent leur énergie par respiration ou fermentation. Ces bactéries sont capables de produire des endospores leur permettant de résister à des conditions environnementales défavorables. Celles-ci donneront naissance à de nouvelles bactéries en cas de conditions favorables. Les Bacillus sont hétérotrophes, saprophytes et ubiquitaires. Elles sont fréquemment retrouvées dans le sol où certaines espèces ont un rôle dans le cycle du carbone et de l'azote. On peut trouver des Bacillus dans des denrées alimentaires. Les bactéries du genre Bacillus sont connues comme étant capables de former des inclusions intracellulaires de polyhyxyalcanoates sous des conditions de stress (ex : déficit d’éléments tels que le phosphore, l’azote, l’oxygène combiné avec un excès en sources carbonées).
