Hard outer covering that forms within the plasma membrance to survive periods of unfavorable conditions.
Process of raising the temperature of a liquid to a certain temperature and then cooling it quickly to destroy bacteria.
Occurs when the DNA of one bacteria passes through the conjugation tube (pilus) to another bacteria.
When living bacterial cells pick up another bacteria's DNA that is free in the environment.
