However, in wastewater, it can inhibit the nitrification process and induce the collapse of the nitrification system. In such a case, ammonia-oxidizing bacteria (AOB) lose their ability to remove ammonia. We investigated the nitrification system of a 60,000-t/d municipal sewage t ...

Abstract:
... Plants with ammonium preference are able to exude biological nitrification inhibitors to reduce nitrification keeping the mineral N in NH₄⁺ form. The question is whether plants with a NO₃⁻ preference are able to stimulate nitrification to shift mineral N towards NO₃⁻ production to meet their NO₃⁻ demand. In this study we attempted to solve this conundrum by conducting ¹⁵N tracing studies in a rang ...
