Bacilli are partly or wholly aerobic. They do aerobic respiration. They are every where in nature. Bacillus includes both free-living (non-parasitic) and parasitic pathogenic species.[1]
Under stressful conditions, they produce endospores. These are not true spores, but like survival pods they can stay in a dormant state for long periods.
Some species of Bacillus are worth noting:
- Bacillus anthracis, which causes Anthrax.
- Bacillus subtilis is considered an model organism. It is often used in genetic engineering.[2]
- Bacillus cereus which is responsible for a form of food poisoning.
- Bacillus thuringensis which is used in pest control. It produces a toxin which can kill some moths, and certain butterflies.
