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.
However, the disease-causing Bacillus species are now easily distinguishable from the helpful strains such as Bacillus subtilis. The subtilis species is not to be confused with Bacillus cereus, which is a common cause of food poisoning, and Bacillus anthracis, which is pathogenic to humans and other animals.Bacillus subtilis is beneficial is many ways, including industrial applications.It is used to produce a variety of enzymes, including amylase, which is helpful in the de-sizing of textiles and starch modification for the sizing of paper.acillus subtilis is beneficial is many ways, including industrial applications.
