Bacteria lacking a nucleus
Bacteria that must have oxygen to survive are called obligate aerobes. Some bacteria can live with or without oxygen and are called facultative anaerobes.Anaerobes = No oxygenAerobes = Oxygen
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.
Plants and anaerobic bacteria.
Anaerobic bacteria can survive and reproduce without oxygen by obtaining energy from other sources such as fermentation. Some organisms like certain deep-sea creatures and certain bacteria can adapt to living in oxygen-deprived environments by using alternative metabolic processes. However, the majority of complex organisms, including animals and plants, require oxygen for survival.

Obligate aerobes
Aerobic bacteria must have oxygen to live.
Many types of bacteria can live in Anaerobic conditions, I.e they don't need oxygen to live, as they create energy using anaerobic respiration.
methane
Bacteria that can live in oxygen are known as aerobic bacteria. Some examples include Escherichia coli, Bacillus subtilis, and Pseudomonas aeruginosa. These bacteria use oxygen for their metabolism and growth.
The term that best defines a bacteria that can survive without oxygen is "anaerobic." Anaerobic bacteria do not require oxygen for growth and metabolism.
