| Abstract: | Denitrification in bacteria comprises a series of four reduction reactions; for nitrate, nitrite, nitric oxide and nitrous oxide. Nitrogen gas is the final product. The nature of the enzymes catalysing these reactions is described along with the the properties of the underlying electron transport systems. The factors influencing the expression of the reductases for the four reactions are reviewed along with the effect of oxygen on the activities of the enzymes of denitrification. The main emphasis is on observations made withParacoccus denitrificans andPseudomonas stutzeri. |
