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 subtilis (/ bəˈsɪl.əs subˈtiː.lis /), [3][4] known also as the hay bacillus or grass bacillus, is a gram-positive, catalase -positive bacterium, found in soil and the gastrointestinal tract of ruminants, humans and marine sponges. [5][6][7][8] As a member of the genus Bacillus, B. subtilis is rod-shaped, and can form a tough ...
Binomial name. Bacillus anthracis. Cohn 1872. Bacillus anthracis is a gram-positive and rod-shaped bacterium that causes anthrax, a deadly disease to livestock and, occasionally, to humans. It is the only permanent (obligate) pathogen within the genus Bacillus. Its infection is a type of zoonosis, as it is transmitted from animals to humans. [1]
Bacillus thuringiensis (or Bt) is a gram-positive, soil-dwelling bacterium, the most commonly used biological pesticide worldwide. B. thuringiensis also occurs naturally in the gut of caterpillars of various types of moths and butterflies , as well on leaf surfaces, aquatic environments, animal feces, insect-rich environments, flour mills and ...
Bacillus cereus is a Gram-positive rod-shaped bacterium commonly found in soil, food, and marine sponges. [1] The specific name, cereus, meaning "waxy" in Latin, refers to the appearance of colonies grown on blood agar. Some strains are harmful to humans and cause foodborne illness due to their spore-forming nature, while other strains can be ...
Binomial name. Bacillus licheniformis. (Weigmann 1898) Chester 1901 [1] Bacillus licheniformis is a bacterium commonly found in the soil. It is found on bird feathers, especially chest and back plumage, and most often in ground-dwelling birds (like sparrows) and aquatic species (like ducks). It is a gram-positive, mesophilic bacterium.
Bacillus amyloliquefaciens is a species of bacterium in the genus Bacillus that is the source of the BamHI restriction enzyme. It also synthesizes a natural antibiotic protein barnase, a widely studied ribonuclease that forms a famously tight complex with its intracellular inhibitor barstar, and plantazolicin, an antibiotic with selective activity against Bacillus anthracis.
Bacillus atrophaeus is a species of black-pigmented bacteria. Its type strain is NRRL NRS-213. [2] B. atrophaeus strains have been used extensively in biomedicine as indicator strains for heat- and chemical-based decontamination regimens. Most of the strains in use are derivatives of a lineage of B. atrophaeus that originated at Camp Detrick in ...
