While obligate aerobes require oxygen to survive, other microbes can be killed by oxygen. Through cellular respiration, these organisms use oxygen to metabolise substances, like sugars or fats, to obtain energy.In this type of respiration, oxygen serves as the terminal electron acceptor for the electron transport chain. Although most of the clinically significant anaerobes can be found on most sites of the body, certain genera are more common in certain sites. Therefore, specimens likely to be contaminated with these organisms should not be submitted for culture (e.g., a throat or vaginal swab).

Obligate anaerobic and microaerophilic bacteria live in oxygen free environments (Table 1). Obligate anaerobes are those that thrive only when oxygen is completely absent in the surrounding. (See accompanying table.) Facultative anaerobes can use oxygen when it is present. The catalase reaction forms water and oxygen as it's products. Facultative bacteria gather mostly at the top, since aerobic respiration is advantageous (ie, energetically favorable); but as lack of oxygen does not hurt them, they can be found all along the test tube.

These are bacteria and are thought to have existed since the early times when the Earth had an atmosphere that was devoid of oxygen. Obligate anaerobes typically live in oxygen-free places, such as in the gut of an animal or in the mud. Unlike obligate anaerobes however, they are not poisoned by oxygen. Obligate Anaerobes. Do not have permission to write for eukaryotic cell biology of molecules. However, microaerophiles … … They are obligate anaerobes, which appear as rod shaped when observed under the microscope. Despite the inability to grow under anaerobic conditions, many obligate aerobes can survive transient exposure to O2 and reactive oxygen species." facultative anaerobe a microorganism that can live and grow with or without molecular oxygen. 1. If they don't, they are called obligate anaerobes and cannot handle oxygen. Obligate anaerobes are destroyed when exposed to the atmosphere for as briefly as 10 minutes. Before we delve into examples, let's quickly go over how these obligate anaerobes eat. obligate anaerobe an organism that can grow only in the complete absence of molecular oxygen.
