their enzyme system necessitates use of O2 as the final hydrogen (electron) acceptor in the complete oxidative degradation of high-energy molecules such as glucose.
Aerobes cannot grow in the absence of O2 molecules. Aerobes need oxygen in order to survive and if they do not have it they cannot survive.
Obligate Aerobes
Bacteria that can ONLY grow in the absence of oxygen are called obligate anaerobes.
coliphages of bacteriophage are seen in solid media
Available Oxygen Microorganisms can be classified according to their oxygen requirements necessary for growth and survival: Obligate Aerobes: oxygen required. Facultative: grow in the presence or absence of oxygen. Microaerophilic: grow best at very low levels of oxygen.

Is an organism that does not need oxygen to survive and grow - it would possibly die with the introduction of oxygen for example: Clostridium Perfringens. Alex
"Absence", it is said, "makes your heart grow fonder."
The cliche is "Absence makes the heart grow fonder."
Vicki agreed with the old saying that absence makes the heart grow fonder. The word absence is a noun that means the state of not being present.
Not all bacteria do. Some can not grow in the presence of oxygen. Those that do (obligate aerobes and facultative anaerobes) grow quicker in oxygen since it facilitiates their energy cycle and ideal environment.
