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.
There are fourteen different capsule types for bacteria. Some  examples are: Bacillus megaterium, Streptococcus pyogenes,  Streptococcus pneumoniae, and Streptococcus agalacâ¦tiae.
