“…By measuring the nitrite formation rates with the colorimetric methods using cell suspensions, the inhibitor toxicity can also be evaluated [1315]. However, the analysis procedures are always complex and time-consuming [16]. Furthermore, the reagents used are harmful to human health and may contaminate the environment.…”

“…Once the activity of nitrifying bacteria is inhibited, and it leads to decreased oxygen consumption rate in the system [17]. In fact, several technologies such as the NITRification tOXicity tester (NITROX, [18]) and selective nitrification inhibitor addition respirometry [19] have been applied to detect nitrification inhibition. Since these methods distinguish the oxygen uptake by nitrifying bacteria from that by total sludge, a nitrification inhibitor should be added.…”
