TL;DR: In this article, the adsorption kinetics study showed that the Pseudo-second-order kinetic model could be used to describe both nitrate and nitrite removal satisfactorily.

TL;DR: A profound variation in the performance of CANON process was experienced at high DO exposure and high nitrite concentration, whereas the synergistic inhibition of nitrite, free ammonia and free nitrous acid was irreversible.

TL;DR: Nitrate reductase was less sensitive toward oxygen than nitrite and nitrous oxide reductases, and nitrite reduct enzyme activity rose to a value only 20% that of the original rate after an aerobic–anaerobic shift.
Abstract: Studies on the effect of oxygen on denitrification have shown that denitrification on Pseudomonas nautica 617 can take place in the presence of oxygen. The enzymes associated with denitrification are affected differently with respect to oxygen concentration. Nitrate reductase was less sensitive toward oxygen than nitrite and nitrous oxide reductases. Nitrate reductase activity was completely blocked at an oxygen concentration greater than 4.05 mg/L, compared with 2.15 and 0.25 mg/L for nitrite and nitrous oxide reductases, respectively. After an aerobic–anaerobic shift, nitrate reductase activity remained unchanged whereas the rate of nitrite reductase activity rose to a value only 20% that of the original rate.Key words: denitrification, oxygen, Pseudomonas.

TL;DR: Nitrite- and nitrate-reductase activities of Staphylococcus strains in nitrite-cured sausages were of limited importance regarding colour development, while in nitrate's strains with higher nitrate reductase activity were crucial for ensuring optimal colour formation during initial fermentation stages.
