Bacillus species are Gram-positive, endospore-forming, rod-shaped bacteria that are ubiquitous in the environment. Many species of Bacillus have been placed in other genera including Paenibacillus, Brevibacillus, Geobacillus, and Lysinibacillus. The vast majority of these bacteria are nonpathogenic, environmental organisms found in soil, air, dust,. Bacillus species: Ubiquitous gram-positive, rod-shaped bacteria that can be obligate aerobes or facultative anaerobes, and test positive for the enzyme catalase. Bacillus are known to form intracellular inclusions of polyhydroxyalkanoates under certain environmental conditions The different species of Bacillus produce a variety of extracellular products including antimicrobial substances, enzymes, pigments, and toxins in few species . Enzymes that can be found on culture include amylase, collagenase, hemolysin, lecithinase, phospholipase, protease, and urease The term bacillus has been applied in a general sense to all cylindrical or rodlike bacteria. The largest known Bacillus species, B. megaterium, is about 1.5 μm (micrometres; 1 μm = 10 −6 m) across by 4 μm long. Bacillus frequently occur in chains Bacillus strains are Gram-positive, aerobic, endospore-forming, rod-shaped bacteria. Bacillus subtilis is one of the most extensively investigated species in the genus of Bacillus. The complete genome of it was sequenced in 1997
Bimodal probiotic strains of the Bacillus genus constitute the microbiota of the human environment, and are typically found in soil, water, a number of non-dairy fermented foods, as well as in human and animal GIT Bacillus subtilis is een grampositieve en katalase-positieve bacterie die gewoonlijk in grond voorkomt. De bacterie is staafvormig en kan een endospore vormen, waardoor de bacterie extreme omstandigheden kan overleven. De bacterie is altijd tot de groep obligaat aerobe bacteriën gerekend. Onderzoek heeft echter uitgewezen dat dit niet helemaal juist is. De bacterie kan ook anaeroob leven door gebruik te maken van nitraat of nitriet als een terminale elektronenacceptor of door. Bacillus cereus is een grampositieve, facultatief anaerobe, bèta-hemolytische, staafvormige bacterie die hittebestendige endosporen vormt. De bacterie en de sporen komen wijd verspreid in de natuur voor. Dit verklaart waarom veel plantaardige voedingsmiddelen (zoals graan, rijst en specerijen) B. cereus bevatten Bacillus organisms are gram-positive, motile, aerobic, spore-forming bacterial rods. Typical forms of these Bacillus organisms are vegetative cells and spores Kotiranta et al (2000). Unlike the other species in this genus, B. anthracis is non-motile and is non-hemolytic Spencer (2003)
Bacillus subtilis, 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 and humans. A member of the genus Bacillus, B. subtilis is rod-shaped, and can form a tough, protective endospore, allowing it to tolerate extreme environmental conditions Bacillus species offer several advantages over other bacteria for protection against plant pathogens because of their ability to form endospores and the broad-spectrum activity of their antibiotics and there are numerous reports of Bacillus spp The genus Bacillus is a phenotypically large, heterogeneous collection of Gram-positive or Gram-variable spore-forming, aerobic or facultative anaerobic bacteria that have undergone considerable reclassification following the advances in molecular biology techniques [ 1, 2 ] Many Bacillus species have little or no pathogenicity and are rarely associated with disease in humans or lower animals. Exceptions to this are Bacillus anthracis , Bacillus cereus and Bacillus subtilis . Some species are insect pathogens. B. anthracis is the best known pathogen in the genus. Species in the genus Bacillus can be thermophilic, psychrophilic, acidophilic, alkaliphilic, halotolerant, or halophilic and are capable at growing at pH values, temperatures, and salt concentrations where few other organisms can survive. Bacillus insolitus can grow at 0 degrees celsius and below (Rüger et al., 2000)

B. cirroflagelosus, B. epiphytus & B. filicolonicu Genus Characteristics. Bacillus species are large, Gram-positive, endospore-forming rods. They are known to produce resistant endospores in the presence of O 2 with one exception, B. infernus. This large genus accommodates approximatively 100 species including the well-known zoonotic agent B. anthracis.The bacilli can be divided into three main groups: B. subtilis group (B. subtilis, B.
Endophthalmitis caused by Bacillus species often results in poor visual outcomes. In vitro antibiotic sensitivities indicate that vancomycin, aminoglycosides, and fluoroquinolones were effective against Bacillus isolates, whereas cephalosporins were relatively ineffective Bacillus species are aerobes and the Clostridium species are anaerobes (see also Chapter 21). + + Of the many species of Bacillus and related genera, most do not cause disease and are not well characterized in medical microbiology. There are a few species, however, that cause important diseases in humans Three species of Bacillus viz., B. megaterium, B. subtilis and B. cereus were tested for solubilization of phosphorus in the substrates like poultry bones, fish bones and ash. All the three species produced organic acids and there was a strong correlation between total concentration of organic acids produced and the amount of available phosphorus released from the substrates (Saeid et al. 2018 )

Some Bacillus species are useful in agriculture, especially B. thuringiensis and B. sphaericus are used as insecticides.. What is Clostridium? Clostridium is a genus of anaerobic bacteria. They belong to the phylum Firmicutes. Moreover, they belong to class Clostridia, order Clostridiales. Bacillus licheniformis. Description and significance. Bacillus licheniformis is a bacterium that is commonly found in soil and bird feathers. Birds that tend to stay on the ground more than the air (i.e. sparrows)and on the water (i.e. ducks) are common carriers of this bacterium; it is mostly found around the bird's chest area and back plumage Overview. Bacillus species are mostly non-pathogenic, environmental organisms.. Characteristics. The bacteria are large, motile, Gram positive rods that produce endospores. They are aerobes or facultative anaerobes and are catalase positive and oxidase negative
Although Bacillus species are infrequent causes of human infections, they are known to be responsible for bacteremia without focus, catheter-related bacteremia, endocarditis, endophthalmitis, cerebral spinal fluid shunt infection, meningitis, pneumonia, food poisoning, and wound infections Bacillus. ( ba-sil'ŭs ), A genus of aerobic or facultatively anaerobic, spore-forming, ordinarily motile bacteria (family Bacillaceae) containing gram-positive rods. Motile cells are peritrichous; spores are thick walled and take Gram stain poorly; these organisms are chemoheterotrophic and are found primarily in soil
The Bacillus cereus group comprises numerous closely related species, including bioterrorism agent B. anthracis, foodborne pathogen B. cereus, and biopesticide B. thuringiensis. Differentiating organisms capable of causing illness or death from those used in industry is essential for risk assessment and outbreak preparedness. However, current species definitions facilitate species-phenotype. Spores of Bacillus species generally contain two major CLEs, CwlJ and SleB, either of which alone is sufficient to allow the completion of spore germination. CwlJ and SleB are likely to be lytic transglycosylases, although this has only been shown directly for SleB ( 4 )

Bacillus thuringiensis (Bt), soil-dwelling bacterium that naturally produces a toxin that is fatal to certain herbivorous insects. The toxin produced by Bacillus thuringiensis (Bt) has been used as an insecticide spray since the 1920s and is commonly used in organic farming. Bt is also the sourc The plant growth promoting model bacterium FZB42T was proposed as the type strain of Bacillus amyloliquefaciens subsp. plantarum (Borriss et al., 2011), but has been recently recognized as being synonymous to Bacillus velezensis due to phylogenomic analysis (Dunlap C. et al., 2016). However, until now, majority of publications consider plant-associated close relatives of FZB42 still as B. Bacillus anthracis , Bacillus cereus , and Bacillus thuringiensis are members of the Bacillus cereus group of bacteria, demonstrating widely different phenotypes and pathological effects. B. anthracis causes the acute fatal disease anthrax and is a potential biological weapon due to its high toxicity. B. thuringiensis produces intracellular protein crystals toxic to a wide number of insect.
