This study dealt with a detailed investigation of biological denitrification of nitrate and nitrite by a pure culture of Pseudomonas denitrificans (ATCC 13867), under anaerobic conditions.
In the first part of the study, the kinetics of denitrification were studied in serum-bottle experiments. It was found that reduction of both nitrate and nitrite follows inhibitory expressions of the Andrews type. It was also found that when nitrite is present at levels above 15 mg/L, nitrite and nitrate are involved in a cross-inhibitory, non-competitive, interaction pattern. Analysis of the kinetic data has shown that the culture used has severe maintenance requirements, which …
