Bacteria that must have oxygen to survive are called obligate aerobes. Some bacteria can live with or without oxygen and are called facultative anaerobes.
Archaebacteria called extremeophiles have some species that live entirely anaerobically. Bacteria [and other organisms] that respire using O2 as the 'final' electron acceptor are termed to be Aerobic, while bacteria [and the odd organism] that has the biochemical capacity to Live without O2 are termed to be Anaerobic.
Facultative anaerobic bacteria can survive with or without oxygen, while obligate aerobes require oxygen to survive and obligate anaerobes cannot survive in the presence of oxygen.
Bacteria that need oxygen to survive are called aerobic bacteria.
If they CAN survive without oxygen, they are called facultative anaerobes. In other words, these can survive with or without oxygen.If they CAN ONLY survive if there is no oxygen, they are callled obligate anaerobes. In other words, these can only survive if there is no oxygen.
Yes, some aerobic bacteria can grow in the absence of oxygen using alternative electron acceptors like nitrate or sulfate through a process called anaerobic respiration. This allows them to generate energy without oxygen.

Obligate aerobes.
Anaerobic bacteria are unable to tolerate oxygen. They can only survive in environments without oxygen or in low oxygen conditions.
Facultative anaerobic bacteria can survive with or without oxygen, while obligate aerobes require oxygen to survive and obligate anaerobes cannot survive in the presence of oxygen.
Bacteria do not breathe in the sense that we do, but many do require oxygen. These are called aerobic bacteria. Some bacteria will use oxygen if it is present, but can function without it. These are called facultative anaerobes. Still other bacteria will die if exposed to oxygen. These are called obligate anaerobes.
Bacteria that need oxygen to survive are called aerobic bacteria.

The term that best defines a bacteria that can survive without oxygen is "anaerobic." Anaerobic bacteria do not require oxygen for growth and metabolism.
Bacteria lacking a nucleus
You are a bit confused. Alcohol is generally toxic to bacteria, whether aerobic or anaerobic, but anaerobic bacteria cannot live in the presence of oxygen, that's why they are called anaerobic.
