some resistance to acidic environments. The silica coat is related to the permeability of the spore's inner membrane. Strong mineral acids are able to break down spore permeability barriers and kill the spore. However, when the spore has a silica coating, it may reduce the permeability of the membrane and provide resistance to many acids.

Metabolism

Bacillus cereus has mechanisms for both aerobic and anaerobic respiration, making it a facultative anaerobe. Its aerobic
