When oxygen is present in their environment, they use aerobic cellular respiration to produce energy in the form of ATP. If oxygen becomes depleted, they can switch to anaerobic respiration or fermentation. In contrast, obligate anaerobes must live without oxygen. WebA lthough sulphate-reducers are obligate anaerobes, they may survive a temporary exposure to oxygen and again become active under anaerobic conditions. Because of the O 2 mass transfer, the critical DO concentration in the wastewater below which sulphate reduction can occur is 0.1-1.0 mg/l ( EPA, 1985 ). magic tiles 3 on computer
