Describe what occurs when elemental sulfur is provided externally as an electron donor and how energy is obtained
What will be an ideal response?
Answer: Elemental sulfur (S0) can serve as an electron donor for colorless sulfur bacteria. Aerobic chemolithotrophy of S0 uses elemental sulfur, oxygen, and water to form sulfate ions. The reduced sulfates can then enter the electron transport chain to produce a proton motive force, ultimately driving the production of energy in the form of ATP.
