Priestia megaterium [1] (Bacillus megaterium prior to 2020) [2] is a rod-like, Gram-positive, mainly aerobic, spore forming bacterium found in widely diverse habitats. [ 3 ] [ 4 ] It has a cell length up to 100 μm and a diameter of 0.1 μm, which is quite large for bacteria. [ 5 ]
Priestia, as of May 2021, contains 10 species with validly published names. [3] This genus was identified as a monophyletic clade and phylogenetically unrelated to other Bacillus species in studies examining the taxonomic relationships within Bacillus. [1] This branching pattern is also observed in the Genome Taxonomy Database. [10]
Bacillus (Latin "stick") 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.
An endospore stain of the cell Bacillus subtilis showing endospores as green and the vegetative cell as red Phase-bright endospores of Paenibacillus alvei imaged with phase-contrast microscopy. An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Bacillota.
Bacillus megaterium for example, synthesizes a capsule composed of polypeptide and polysaccharides. Bacillus anthracis; Streptococcus pyogenes synthesizes a hyaluronic acid capsule. Streptococcus pneumoniae [20] has at least 91 different capsular serotypes. [21] These serotypes are the basis for the pneumococcal vaccines.
