Bacillus megaterium cells stained with Sudan Black B and safranin. Bacillus megaterium is a rod-like, Gram-positive, mainly aerobic, spore forming bacterium found in widely diverse habitats. [1][2] It has a cell length up to 100 μm and a diameter of 0.1 μm, which is quite large for bacteria. [3] The cells often occur in pairs and chains, [1 ...
Priestia is a genus of mostly Gram-positive (P. flexa stains Gram-variable and P. koreensis stains Gram-negative), rod-shaped bacteria in the family Bacillaceae from the order Bacillales. [ 1 ][ 2 ] The type species of this genus is Priestia megaterium.[ 3 ] Members of Priestia are previously species belonging to Bacillus, a genus that has been ...
Cytochrome P450 BM3 is a Prokaryote Cytochrome P450 enzyme originally from Bacillus megaterium catalyzes the hydroxylation of several long-chain fatty acids at the ω–1 through ω–3 positions. This bacterial enzyme belongs to CYP family CYP102, with the CYP Symbol CYP102A1.This CYP family constitutes a natural fusion between the CYP domain ...
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. Bacillus species can be either obligate ...
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.
Bacillus subtilis is a model organism used to study bacterial chromosome replication. Replication of the single circular chromosome initiates at a single locus, the origin (oriC). Replication proceeds bidirectionally and two replication forks progress in clockwise and counterclockwise directions along the chromosome.
A Bacillus phage is a member of a group of bacteriophages known to have bacteria in the genus Bacillus as host species. These bacteriophages have been found to belong to the families Myoviridae, Siphoviridae, Podoviridae, or Tectiviridae. [1][2][3][4] The genus Bacillus includes the model organism, B. subtilis, and two widely known human ...
Cereulide is a toxin produced by some strains of Bacillus cereus, Bacillus megaterium and related species. It is a potent cytotoxin that destroys mitochondria. It causes nausea and vomiting. Cereulide acts as ionophore with a high affinity to potassium cations.
