Bacteria that must have oxygen to survive are called obligate aerobes. Some bacteria can live with or without oxygen and are called facultative anaerobes.

Facultative anaerobes are bacteria that can live with or without oxygen. Bacteria that die when exposed to oxygen are called obligate anaerobes.

Aerobic bacteria cannot live without oxygen. Obligate aerobes need oxygen for respiration and fermentation processes. Many need oxygen to metabolize sugars and fats.

Do Bacteria breath 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 can survive without oxygen are?

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.

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.
