anaerobic respiration
The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which uses compounds other than oxygen (e.g. nitrate, sulfate) as the terminal electron acceptor.
sulfur respiration
type of respiration used by some anaerobic bacteria; oxidative phosphorylation with elemental sulfur as the terminal electron acceptor instead of O2
dissimilatory sulfate reduction
form of anaerobic respiration where sulfate is the terminal electron acceptor
