Solution

Answer:

1. Sulfate is the electron acceptor in sulfur redox reactions.

2. H2, hydrocarbons and other organic compounds acts as the electron donor in sulfate redox reactions.

3. M. oxyfera uses oxygen as a electron acceptor in denitrification.

4. M. oxyfera uses methane as an electron donor in denitrification.
