This book chapter focus on the food-poisoning implications of Bacillus species. Before giving details on the food poisoning potential, the type of toxins and the method of detection, it briefly introduces the complex ecology and the identification challenges that characterize several Bacillus species. It uses use as an example the B.

Siderophores of Bacillus anthracis, Bacillus cereus, and Bacillus thuringiensis
Biochemical and Biophysical Research Communications, 2006Three Bacillus anthracis Sterne strains (USAMRIID, 7702, and 34F2) and Bacillus cereus ATCC 14579 excrete two catecholate siderophores, petrobactin (which contains 3,4-dihydroxybenzoyl moieties) and bacillibactin (which contains 2,3-dihydroxybenzoyl moieties). However, the insecticidal organism Bacillus thuringiensis ATCC 33679 makes only bacillibactin.

Cytochromes of Bacillus megaterium and Bacillus subtilis
Archives of Biochemistry and Biophysics, 1960Abstract Treatment of Bacillus subtilis and Bacillus megaterium cells by ordinary procedures failed to extract any soluble cytochrome from the cell. Sonoration produced small fragments which contained the cytochrome complement and were sedimentable in a centrifugal field of 144,000 × g .

Systematic and Applied Microbiology, 1997
Summary An aerobic, endospore forming thermophilic microorganism was isolated from a soil sample in Jordan. The cells stained Gram-positive and the cylindrical spores are terminal and wider than the mother cell. Growth occurs at temperature values between 45 °C and 70 °C, with an optimum at 55°C. The optimum pH for growth is 7.0. The G + C content of

Electroporation of Bacillus thuringiensis and Bacillus cereus
2000Contrary to Bacillus subtilis, no natural transformation has so far been described for bacteria of the Bacillus cereus group (B. cereus sensu lato), namely B. anthracis,B. cereus sensu stricto, B. thuringiensis and B. mycoides. Moreover, other methods (protoplast, autoplast or vegetative cell transformation) were found to be particularly difficult to ...

Bacillus cereus and Bacillus anthracis
2018Bacillus species are spore-forming aerobic rods; are natural inhabitants of soil, dust, water, and environment; and can contaminate milk, meat, rice, and pasta. Endospores are resistant to harsh environmental conditions or processing treatments. The majority of bacilli are nonpathogenic; however, several species produce multiple toxins and can cause ...

Bacillus cereus/Bacillus thuringiensis
1998Bacillus cereus/Bacillus thuringiensis (B.t.) are spore-forming soil bacteria, the only established difference being the production by B.t. of insecticidal toxins, present as intracellular crystals during sporulation (Aronsen, 1993; Priest, 1981; Carlson & Kolsto, 1993; Carlson et al., 1994.) B.t. is the most widely used biopesticide in the world today.

spoVG sequence of Bacillus megaterium and Bacillus subtilis
Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, 1992We have sequenced the stage V sporulation specific gene spoVG in both Bacillus megaterium and Bacillus subtilis. The open reading frames encode polypeptides of 96 and 97 residues, respectively, and have an 88.6% amino acid identity. Both genes have putative rho-independent terminators. No significant amino acid or nucleotide homology of either gene was

Tubercle, 1960
Summary Some aspects of the morphology, growth requirements and resistance of a myco-bacterium isolated from the South African rodent Cape hydrax, Procavia capensis (Pallas) or ‘Dassie’, have been described. The morphology and starning features of this ‘Dassie’ bacillus resemble closely that of the Mycobacterium var: muris or vole bacillus ...
