Depends on the bacteria. Aerobic bacteria have electron transport chain enzymes in their cell membranes. Mitochondria are thought to have evolved from such bacteria. There are many bacteria that live in anaerobic environments, that dont need oxygen to survive, however. Those bacteria may reduce sulfur, or other compounds, instead of oxygen.
