Anaerobic bacteria are not likely to carry out cellular respiration. Cellular respiration requires oxygen, and anaerobic bacteria are able to survive in environments that lack oxygen.
There are three types of anaerobic bacteria: facultative anaerobes, obligate anaerobes and aerotolerant bacteria. Facultative anaerobes are bacteria that prefer oxygen in their environment so that they can carry out cellular respiration, but they are able to survive if oxygen is not present. By contrast, oxygen is toxic to obligate anaerobes, and they must live in environments that do not have oxygen. Aerotolerant bacteria prefer conditions that have no oxygen, but they are able to survive in environments where oxygen is present.
