WebThe study of obligate anaerobes requires special equipment. Obligate anaerobic bacteria must be grown under conditions devoid of oxygen. The most common approach is culture in an anaerobic jar (Figure 9.21). Anaerobic jars include chemical packs that remove oxygen and release carbon dioxide (CO 2). WebMar 5, 2024 · Obligate anaerobes use molecules other than oxygen as terminal electron acceptors. Facultative anaerobic organisms, which are usually prokaryotic, make ATP by aerobic respiration, if oxygen is present, but can also survive without oxygen. In the absence of oxygen they switch to the process of fermentation to make ATP.
