A dreidel is a four-sided spinning top with a Hebrew letter on each side. It is used during Hanukkah to play a popular children's game that involves spinning the dreidel and betting on which Hebrew letter will be showing when the dreidel stops spinning.
The capsule is not synthesized by the closest relatives of B. anthracis, i.e., B. cereus and B. thuringiensis, and this criterion can be used to distinguish the species. Cell Walls The variability of cell wall structure that is common in many Gram-positive bacteria does not occur in the genus Bacillus. few species, such as Bacillus megaterium, require no organic growth factors; others may require amino acids, B-vitamins, or both. The majority are mesophiles, with temperature optima between 30 and 45 degrees, but some are thermophiles with optima as high as 65 degrees.
Bacteria display a large diversity of cell morphologies and arrangements. A bacillus (plural bacilli) is a rod-shaped bacterium. Bacilli are found in many different taxonomic groups of bacteria. However, the name Bacillus, capitalized and italicized, refers to a specific genus of bacteria.The name Bacilli, capitalized but not italicized, can also refer to a less specific taxonomic group of bacteria that includes two orders, one of which contains the genus Bacillus.owever, the name Bacillus, capitalized and italicized, refers to a specific genus of bacteria.
