An organism, especially a bacterium, that does not require oxygen or free oxygen to live.
Organism which does not need molecular oxygen for life. Obligate (strict) anaerobes grow only in the absence of oxygen. Facultative anaerobes can grow either in the presence or in the absence of molecular oxygen. Nagel et al. (eds), 1991 AN aerobe.
organism that wants very little or no oxygen
An organism, such as many bacteria or archaea, that can live in the absence of free oxygen. Anaerobes may be facultative, indifferent to the presence or absence of oxygen, or obligate. Obligate anaerobes are actually poisoned by oxygen. In some cases their ancestors may never have lived in an environment with oxygen, and such obligate anaerobes may be descendants of very primitive organisms.

An organism that can live without oxygen.
A microorganism capable of growth in the absence of oxygen. Facultative anaerobes can, for example, use nitrate in the absence of oxygen. Strict anaerobes cannot abide the presence of any oxygen.
AN-air-robe Organism that can live in an environment lacking oxygen. 127
A microorganism that is capable of growing in the complete absence of oxygen. Some of these organisms may also be able to grow in oxygenated conditions (facultative aerobes), whereas others cannot tolerate oxygen and are killed when exposed to air. Such organisms are termed obligate anaerobes.
an organism that does not employ oxygen as a terminal electron acceptor.
Micro-organisms that survive without oxygen (air)
An organism that can grow under either aerobic or anaerobic conditions.
An organism that grows only in the absence of free oxygen (e.g., sulfate reducing bacteria).
An organism that lives only in the absence of oxygen.
An organism that does not require molecular oxygen for growth.
