When nitrate is used in a biological electron transport
system as the final acceptor of hydrogen to form water,
the system is characterized as "Nitrate Respiration." However,
the quantitative expression of the over-all participation
of NO₃⁻(0) in the oxidation of glucose by denitrifiers
such as Pseudomonas stutzeri deserves clarification.
