What is the difference in colony morphology between bacillus cereus bacillus megaterium and bacillus subtilis?

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.
