How can facultative anaerobes exist without catalase?

Web5. Catalase-negative bacteria may be anaerobes, or they may be facultative anaerobes that only ferment and do not respire using oxygen as a terminal electron acceptor. A facultative anaerobe is an organism that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation or anaerobic respiration if oxygen ... WebAnaerobic Chambers. The cultivation of anaerobic bacterial species requires an anaerobic chamber. This is a special chamber is a closed environment without O 2 where the microbiologist can work with and cultivate obligate anaerobes without exposing them to oxygen.
