N2 - Anammox bacteria are inhibited by nitrite, which is one of their substrates. By utilizing 2,4 dinitrophenol and carbonyl cyanide m-chlorophenyl hydrazone, two uncouplers of respiration, we demonstrate that nitrite tolerance of anammox cells is strongly dependent on their ability to maintain a proton gradient, which may be the driving force for active nitrite transport system.
