The FNR (defective in fumarate and nitrate reduction) protein of E. coli is an oxygen – responsive transcriptional regulator required for the switch from aerobic to anaerobic metabolism [1]. "Type III mutants, originally frdB , were designated fnr because they were defective in fumarate and nitrate reduction and impaired in their ability to ...
Aerobic denitrification, or co-respiration, the simultaneous use of both oxygen (O 2) and nitrate (NO − 3) as oxidizing agents, performed by various genera of microorganisms. [1] This process differs from anaerobic denitrification not only in its insensitivity to the presence of oxygen, but also in its higher potential to form nitrous oxide ...

Aerobic denitrification, conducted by aerobic denitrifiers, may offer the potential to eliminate the need for separate tanks and reduce sludge yield. There are less stringent alkalinity requirements because alkalinity generated during denitrification can partly compensate for the alkalinity consumption in nitrification.
In aerobic respiration, the pyruvate generated from glycolysis is converted to acetyl-CoA. This is then broken down via the TCA cycle and electron transport chain . Anaerobic respiration differs from aerobic respiration in that it uses an electron acceptor other than oxygen in the electron transport chain.
