Bacillus subtilis is a gram-positive bacterium, and its cells are rod shaped. The bacteria are usually cultured in Tryptone Soya Agar, and the colonies appear wrinkled, dull and raised. This bacterium colonizes vegetation and is prevalent in the soil.
B. subtilis spores have surface irregularities on the order of 7 to 40 nm in size and it will grow on any agar. Since they are motile, they can produce odd rotating structures especially if the agar is soft.
Colonies are large, irregular and flat with an undulate margin
elevation :umbonate
edge;entire with undulate
internal charectaristics :rough
color: creamy offwhite.
The morphology, which refers to the shape of the bacteria, would be rods (bacillus). The arrangement in relation to the other cells would be chains. They will also be large (mega).
Bacillus is a Gram Positive Rod shape irregular Bacteria.

Polymyxin B is the agar and broth that is used for bacillus cereus for cultivation.
No
Yep.
it's susceptable. i found that erythromycin had a very strong effect on bacillus cereus, especially when compared to the effect that streptomycin, tetracycline, and penicillin had.
Because bacillus cereus is a Gram-positive, spore-forming, and rod-shaped, it\'s only able to ferment glucose.

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.
bacillua cereus
its a enemy
Yep.
