Abstract
A study was made of the influence of nitrite, and of certain other ions, on nitrite oxidation by Nitrobacter at normal and lowered oxygen concentrations. Ions similar in structure to nitrite (nitrate, arsenite and cyanate) inhibited nitrite oxidation at normal oxygen concentrations and stimulated nitrite oxidation at decreased oxygen concentrations. Other ions (chloride and sulphate) had little effect at any oxygen concentration. It was confirmed that nitrite inhibited its own oxidation. The nitrite concentration at which a maximum rate of oxidation occurred decreased as the oxygen concentration was decreased.Keywords
