They are Gram positive:dark blue or violet.
Bacillus cereus typically forms large, flat, and irregular colonies with a rough texture and a translucent to opaque appearance. Bacillus megaterium produces larger colonies that are often circular, smooth, and can have a glossy surface. In contrast, Bacillus subtilis colonies are usually smaller, more spreading, and may appear rough or undulate, often exhibiting a characteristic matte texture. Overall, the differences in size, shape, and surface texture help distinguish these three Bacillus species in culture.
Polymyxin B is the agar and broth that is used for bacillus cereus for cultivation.
Bacillus cereus is positive for the urease test, meaning it can break down urea to produce ammonia and increase the pH of the media. This can be observed by a color change in the media from yellow to pink or magenta.

bacillus cereus
Rice and wheat. Bacillus cereus spores are found in cereal grains.
bacillua cereus
its a enemy
Bacillus subtillus will test positive when performing a VP and Citrate test. Also, bacillus cereus is much more motile. It isn't as dependable as the chemical tests, but the cereus colonies will appear wispy and more widespread on an agar plate than those of subtilis.
bacillus megatarium test positive for sucrose where creus doesnt
Bacillus cereus is a Gram positive, soil dwelling ,beta hemolytic , endemic bacterium. It causes food borne diseases.It is a facultative anaerobe and like other members of the genus Bacillus,, produces endospores.
