Enhanced denitrification in Paracoccus denitrificans PD1222 by electrical field application

“…P. denitrificans is renowned for its ability to carry out biological denitrification, an anaerobic respiratory process. This process parallels that of aerobic microorganisms, with nitrate (NO − 3 ) and nitrite (NO − 2 ) ions taking the place of O 2 as the final electron acceptors (Olaya-Abril et al, 2018;Romualdo-Martínez et al, 2022), It is worth noting that not all nitrogen oxidation-reduction processes qualify as denitrification. Only those tied to ATP synthesis are regarded as such (Azziz et al, 2016).…”

“…This nitric oxide is then reduced to nitrous oxide by nitric oxide reductase (Nor). Finally, nitrous oxide is converted to nitrogen gas by the enzyme nitrous oxide reductase (Nos) (Romualdo et al, 2022;Galliazzi, 2017;Qian et al, 2016;Zhang et al, 2023).…”
