They Acquire at the highest from the tube exactly where the oxygen focus is best. 2: Obligate anaerobes are poisoned by oxygen, so they Get at the bottom in the tube wherever the oxygen concentration is cheapest. 3: Facultative anaerobes can develop with or without oxygen as they can metabolise Vitality aerobically or anaerobically. They Assemble primarily at the best for the reason that aerobic respiration generates far more ATP than both fermentation or anaerobic respiration. four: Microaerophiles need oxygen given that they are not able to ferment or respire anaerobically. nevertheless, they are poisoned by significant concentrations of oxygen.
